Bells of Ireland
Scientific name: Moluccella laevis
Bells of Ireland are gorgeous green flowers that grow in tall spires, each flower looking like a bell. While the flowers are green, these are only the calyces. The true flowers are inside the showy green bells, taking the form of tiny, fragrant white flowers. They are great to cut and bring inside, and they are also very pretty when dried.
It blooms from July through to September; they are an annual plant. The calyces stay attractive for a good amount of time until around the late summer when they begin to turn beige. They also become papery before the seed comes in.
Bells of Ireland grow to be 2 to 3 feet tall, and spread 1 to 1.5 feet across. It enjoys full sun, but can tolerate light shade. It can also handle poor soils relatively well, provided that drainage is adequate. However, it much prefers loose, fertile, moderately moist soil.
You can plant this flower a little bit before the final frost, and warmer areas may even sow the seeds in the fall. However, know that the plants perform best in cooler summer climates. These flowers thrive best in USDA hardiness zones 2 through 11.
Scientific name: Zantedeschia aethiopica
The iconic calla lily is best known to grow elegant, white flowers. However, in many cases, they can also come in green. Calla lilies are actually not true lilies and are more related to jack-in-the-pulpits. They grow directly from rhizomes and are, interestingly, technically stemless! These flowers are incredibly popular cut and are a favorite for wedding bouquets.
The bloom time for calla lilies is June through July. They do best in moist soil and will love the full sun. However, they also tolerate partial shade very well. It’s a good idea to leave them in partial shade if your summers are very warm. You can also choose to plant calla lilies in up to 12 inches of water, using mud. They’re popular for water gardens, so this may be something to keep in mind if you keep one!
You can opt to grow calla lilies indoors; simply bring them in before the first frost and ensure that they receive plenty of light. They will make beautiful house plants. It’s important to make sure that when growing calla lilies, you ensure that rhizome rot does not occur. Beyond this, they can be planted outdoors after the spring frosts. They grow best in USDA hardiness zones 8 through 10.
Scientific name: Dianthus caryophyllus
Carnations are a favorite flower for many. Their ruffled petals are elegant and beautiful, and they come in a wide array of colors, including green. It is an herbaceous perennial that can grow anywhere from 6 inches to 5 feet tall, depending on the cultivar! They are popular as mother’s day gifts and make a great addition to any bouquet.
Carnations grow best in average soils that are moderately and evenly moist, provided that there is good drainage. You will get the best performance if you plant these flowers in loamy, organically rich soil; it will be a good thing to break out the compost!
They enjoy the full sun; this is what creates the best flowers. However, they also prefer cooler climates where the summers are not harsh. You can choose to grow this plant as an annual. Deadheading your carnations can encourage more blooms, so it’s a good idea to look into that if you want a longer bloom period.
Overall, the carnation is fairly low maintenance and will work fabulously in your home as cut flowers or when used for gifts. They are fairly resistant to disease and pests, though you should watch for crown rot when possible. Carnations grow best in USDA zones 5 through 9.
Scientific name: Chrysanthemum
Chrysanthemums are known to come in a range of colors despite their etymology, where “chrysos” is the Greek word for “gold.” It’s safe to say that they are a very popular flower, and so is the green color they sometimes come in. They are a fall favorite flower, being able to bloom from September until the frost.
Chrysanthemums enjoy the full sun; this helps them flower to their fullest potential, so ensure that they are getting the sunshine they need. However, they can tolerate partial shade if it gets very hot where you live. They will also need fertile, rich soil that is evenly and consistently moist. It’s worth noting that they grow a bit tall, ranging from 1.5 to 2 feet in height. They spread around 1 to 1.5 feet across.
If you plan to keep these plants, it is a good idea to cut them back down to 6 inches after the flowering period and to mulch the soil to give adequate protection from the winter. Still, this may not always ensure their survival. It may be better to use this plant as an annual instead and replace them as necessary. They grow best in USDA zones 5 through 9.
Scientific name: Celosia
Cockscomb is a gorgeous, vibrant plant that grows showy flowers reminiscent of a rooster’s comb– this is where they get their name. While they are traditionally red, it’s possible for them to come in green, as well. They are a great annual addition to the garden and will reseed enough to stay present year after year, even after the original plants are gone.
With regard to growth patterns, cockscomb can be full of surprises. Some varieties grow only a few inches tall, while some grow several feet tall! Cockscomb loves the sun and heat, and may even be drought tolerant in some cases. Giving them full sun allows them to grow to their best potential, though they can happily coexist in the shade of other plants as well. You should plant these flowers in rich soil that has good drainage.
Pinching back the first bloom can create more showy blooms for the cockscomb plant, so it’s a good idea to try this if you’d like more flowers. You can opt to grow the seedlings indoors upon purchase, though if you live somewhere warmer, it may be a good idea to plant them directly in the soil. Cockscomb is a perennial in USDA zones 10 through 11, it is an annual plant elsewhere.
Scientific name: Cymbidium
While some Orchids are blue flowers, the beautiful and showy, cymbidium orchids grow large flowers in sprays of many different colors, including green. They are a fair amount more cold-tolerant than most orchids are. The flowers themselves last anywhere from one to three months when cared for properly. Cymbidium orchids bloom from mid-autumn through mid-spring, so you have a long time to enjoy their blooms.
As your cymbidium orchids grow, they will appreciate dappled sunlight. When planted outdoors, they should never be in the direct light of the sun. You can opt to keep them in pots, sun them for a few hours, and move them back to shade in the afternoons. Keep in mind that if the plant does not have apple green leaves and they have leaves of a darker green shade, they probably won’t produce very good flowers. Grow these orchids in loamy humus. Loose, rich potting material should suit your purposes just fine.
When choosing to plant cymbidium orchids, it is best to start with a well-established, store-bought plant. Wait until after the flowering period to plant it in the ground or repot it. This is because it may take years for a new seedling to develop any flowers at all. These plants grow best in USDA zones 10 through 12.
Scientific name: Dahlia
Dahlias are beautiful, multi-layered flowers that come in a rainbow of colors, including green. They are often used as cut flowers but have great use in the garden as well. It takes some care to get them to bloom their best, but the results are well worth it. It’s also worth mentioning that newer cultivars have been bred to make growing dahlias easier. It may be good to look into these if you are a beginner gardener.
Dahlias grow from tubers and are easily grown indoors in early spring to start them off right. After the frost clears you can then move them outdoors. They bloom from mid-summer up until the first frost. Lots of blooms will come from lots of sunlight, so be sure that your dahlias get enough, full sun is recommended. They love moist, loamy soil provided that it is well-drained. They will need one to two inches of water per week after they’ve sprouted.
Timing the planting of your new dahlias will be important, as they do not set up well in cold soil. Around 60 degrees Fahrenheit will suffice for the ground temperature. Saving the tubers for the winter will mean giving them a bit of humidity to prevent them from drying out. Dahlias grow best in USDA zones 7 through 10, given enough protection in the winter.
Scientific name: Hemerocallis
Daylilies are stunning perennials that come in a multitude of colors, including a lush, gorgeous green. They bloom throughout the spring up until late summer, so you have a good amount of time to enjoy the flowers. They are easy to grow and will be a great choice for novice gardeners. These flowers are excellent for borders and edging, as well as cut to brighten up the home.
Depending on the cultivar, daylilies can grow anywhere from 8 inches to 5 feet tall, which is quite a large range! While they are tolerant of light shade, daylilies love the sun (as their name suggests) and will be happiest in a full sun environment. Fertile, medium-loamy soil is a good fit for these plants and will give them plenty of nutrients to grow up nicely. During the first growing season, they must be watered regularly. Straw mulch is a good idea to protect them during the winter, provided that the crown is not covered.
Pruning your plants to prevent seeding will allow more blooms to grow, so be sure to remove seed pods where necessary. You should also remove leaves that have yellowed during the growing season. Daylilies are happy in most environments and thrive best in USDA zones 3 through 10.
Dianthus ‘Green Ball’
Scientific name: Dianthus barbatus
Dianthus, of the ‘green ball’ variety, is a happy little plant that grows fluffy, green, pom pom-like flowers. These are round and fuzzy and will make a great statement in your garden. They grow from stiff stems that have glossy green leaves and are quite stunning in most applications. We think they do great as an interesting addition to bouquets as well!
These plants grow 10 to 14 inches tall and spread 8 to 12 inches wide. They enjoy the full sun, so be sure to give them a spot in the garden that gets a lot of sunlight. However, it may be a good idea to let them have shade in the afternoons if you live in a place that gets very warm summers. They enjoy organically rich soils that are well-drained; it may be good to break out the compost to ensure the best growth and the most blooms. They make a great option for borders, though they can also be stunning when planted in containers.
When planting green ball dianthus, you can opt to plant the seeds in the springtime to expect flowers the next year. It’s important to ensure good drainage in the soil to prevent crown rot and rust. Pesticide may also be necessary to deter slugs and similar pests. This plant grows best in USDA zones 3 through 9.
Scientific name: Nicotiana alata
Flowering tobacco is a relative of true tobacco, though this plant is grown for its flowers which produce an attractive fragrance. They are capable of blooming very nice, green flowers. They make a great addition to cottage gardens for their rustic aesthetic. Flowering Tobacco comes in a large variety of sizes, ranging from small ones that are suitable for containers to ones that grow up to 15 feet tall, better suited for staking towards the back of the garden.
Flowering tobacco blooms in the summer and fall. They are very easy to grow as long as you give them moist, well-drained soil. Rich soil means a lot of blooms, so using compost is an excellent idea. While they will be happiest in consistent moisture, flowering tobacco is capable of handling a little bit of drought, which just makes it easier to maintain them. Full sun is recommended for this plant, though some varieties will also be happy in partial shade.
Given that tobacco plants are poisonous, these plants should be placed somewhere that kids and pets cannot get to. On the bright side, they are virtually pest-free for this reason as well. Flowering tobacco grows best in USDA zones 10 through 11.
Scientific name: Gerbera
The gerbera daisy is one of the most cheerful flowers out there. They have ray-like petals surrounding a round center, containing tiny flowers that are either black or green. They are perfect as a cut flower, though they are sure to brighten up any spot of the garden you may choose to put them in.
You should give your gerberas full sun to ensure the best blooms. However, they will not enjoy excessively hot conditions. If you live somewhere warm, it’s a good idea to plant them where there is shade in the afternoons. Gerbera daisies love moist soil that is well-drained and will prefer either a neutral or acidic soil pH.
They will need regular watering; frequent watering may be necessary during the establishment period. Take care not to water them too much during the wintertime, as they do not need much to be revived come the spring.
Gerbera daisies should be planted in the springtime after the threat of frost is no longer there. You can choose to grow them from seeds and find that they establish themselves quite well in a moderate amount of time. They also can be grown from starts. Expect to wait 3 to 4 months for the first blooms to appear; they will continue blooming well through the summertime. They grow best in USDA zones 8 through 10.
Scientific name: Gladiolus
The gladiolus is a spectacular plant that grows charming flowers in tall spires that can get up to 2 to 5 feet tall. They come in a wide array of colors, including green, so they may just be the thing to add some verdant beauty to your garden! The trumpet-shaped flowers are a delightful sight and add visual interest to cut arrangements.
Gladiolus plants are happiest when they have full sun, though it may be a good idea to give them shade if you live somewhere that is particularly hot. Partial shade in the afternoons can be good for this plant, just bear in mind that full sun is what makes it bloom best. Gladiolus plants enjoy soil with a sandy, loamy quality, having a relatively neutral pH. They still grow fine in other types of soil as long as it is well-drained.
With regard to water needs, water gladiolus plants often when they are establishing themselves. Beyond that, when well-established, water them weekly. You will need to stake these flowers to keep them looking great and standing tall. Plant your gladioli in good temperatures; around 60 degrees Fahrenheit in the nighttime is good to aim for. Gladiolus plants grow best in USDA zones 7 through 10.
Scientific name: Hydrangea macrophylla
Hydrangeas are a popular garden plant. These large shrubs grow very showy clusters of flowers that come in a wide range of colors, including green. When mature, hydrangea shrubs can grow up to 15 feet. They grow quite fast and will average around 2 feet of growth each year.
Give your hydrangeas a good amount of sunlight. They will be satisfied in partially shaded areas as long as they get enough sun in the mornings. They also thrive in full sun, but you should be sure to give them plenty of water on particularly hot days.
Hydrangeas are happy in most different types of soil, though you should ensure that it is well-drained. Watering should be done very deeply at least once a week, especially if it has not rained that week. This is even more important during hotter summer days, but it’s important not to overwater either.
Pruning your hydrangeas will not be very necessary, but you can still do it if you’d like to minimize the size of the shrub. Hydrangeas grow best in milder temperatures and will need shelter from the elements during the wintertime. They also enjoy high amounts of humidity and thus thrive well in coastal areas. Hydrangeas are happiest when they are planted in USDA zones 5 through 9.
Scientific name: Arisaema triphyllum
The jack-in-the-pulpit is an interesting plant that grows even more interesting flowers. Truth be told, the structure known as the flowers is a stalk, or spadix, that grows within a hooded cup, called a spathe. The actual flowers of this plant are tiny, lining the spadix. Regardless of the true nature of these flowers, the jack-in-the-pulpit makes a great ornamental plant suitable for any garden that needs extra greenery.
Jack-in-the-pulpit plants are fairly easy to grow as long as you have the right conditions. They enjoy the shade, as this is where they grow wild in more wooded areas. As for soil, jack-in-the-pulpit will be happy even in poorly-drained soil. They prefer moist, and sometimes even wet, soil conditions. This makes them a great addition to rain or shade gardens.
You can opt to use ferns as companion plants, as this is a striking combination. Remember that jack-in-the-pulpit will enjoy organically rich soil, so it is good to mix compost in with the soil prior to planting.
You can choose to mulch jack-in-the-pulpit plants with organic mulch, and then replace it every spring. You will find that jack-in-the-pulpit plants will not be prone to pests or disease, but might be bothered by slugs every now and again. Using traps and slug bait should deter these pests. Jack-in-the-pulpit grows best in USDA zones 4 through 9.
Scientific name: Alchemilla
Lady’s mantle is a plant that will add gorgeous, rustic charm to any cottage garden. It’s an herbaceous perennial that has few needs in terms of maintenance and produces pretty, light green flowers. You can opt to use them as ground cover in areas that need it. Interestingly, lady’s mantle is also used to make cosmetics such as soaps and lotions.
Lady’s mantle enjoys both the full sun and the part shade, though they will flower more with more sunlight. Hot climates will need you to give this plant at least partial shade in the afternoons, though. With regard to soil, lady’s mantle is good in pretty much any kind of soil, provided that the pH is neutral to slightly acidic.
It will be easy to keep this plant happy when watering them, as they can be drought-tolerant once they have established themselves well enough. However, full sun conditions will require you to water them regularly to prevent them from drying out. Fertilizer is hardly necessary; only fertilize if soil conditions are poor.

Scientific name: Euphorbia characias
Mediterranean spurge is an eye-catching evergreen sub-shrub that will flower in light green for many months of the year. They grow anywhere from 3 to 4 feet tall and will spread around the same amount wide. You will enjoy this plant most as a focus for beds and borders, and they will do well in rock gardens or Mediterranean-style gardens too.
This plant is very easy to take care of past the establishing period. Once well-established, they become fairly low maintenance and can take care of themselves for the most part. They will prefer the full sun, thriving well in the heat.
Dry to medium soils are a good choice for Mediterranean spurge, as long as they are well-drained. They are quite drought-tolerant, though it will be a good idea to give them some more water in particularly dry conditions, such as arid summers. Humid summers are not good for this plant either, though, so bear this in mind when selecting it for your garden.
Water this plant when the soil is dry to the touch, and try to penetrate the first few inches of soil. They may do well with some fertilizer, so choose a good organic one to give them the incentive to grow. Mediterranean spurge grows best in USDA zones 7 through 10.
Scientific name: Ranunculus
The ranunculus is a favorite flower for weddings because of its romantic look: multi-layered, ruffly petals coming in an array of colors, including green. They are a great addition to any bouquet of flowers, but make an especially stunning display in gardens, too. They are fairly easy to grow and will be a wonderful, lush addition to your beds.
You should give your ranunculi a lot of sunlight. Full sun, with sunlight hitting them for around 6 hours a day, is a good idea. Ranunculi prefer sandy, loamy soil that has a slightly acidic pH. Ensure that the soil is well-drained to prevent problems later down the line. Be sure to water the bulbs well if you are planting them, but try to hold off on watering them too much, until growth begins to show.
Once your plants have established themselves, we find that they enjoy moist soil. You can create this condition for them by watering once the top layer of soil has begun to dry. Fertilizing your ranunculi may be a good idea; try to do this bi-weekly with a good, organic fertilizer. Ranunculus flowers grow best in USDA zones 8 through 10, and will prefer cool spring weather.
Scientific name: Rosa chinensis viridiflora
Roses are arguably one of the most popular flowers in the world, being a huge favorite for many different applications. It’s interesting to note that in the rainbow of colors that roses come in, green is one of those colors too! Though do keep in mind that they are slightly different from how we know roses to be. They do not grow petals and instead grow green sepals. They are also known as asexual flowers, meaning they do not produce pollen, nor rose hips.
Green roses grow to a height of 3 to 4 feet. They do not really differ in care from other rose varieties, as unique as they may be. It’s a good idea to give your green roses lots of sunlight; around 4 to 6 hours a day should suffice. Being sun-loving, green roses will be tolerant to some amount of drought. They enjoy most types of soil as long as it is well-drained.
You should fertilize these roses in the springtime. Pruning them should be done mostly in the fall, where you can then shape the plant to be the height and width you wish. Green roses are a perennial in USDA zones 5 through 11.
Tropical Lady’s Slipper Orchid
Scientific name: Cypripedium reginae
Tropical lady’s slipper orchid is an interesting orchid that is normally grown indoors, good for places like conservatories or greenhouses. They have unique blooms, showcasing a slipper-shaped pouch – thus its name. This variety of orchid blooms green, making them a good choice for unusual, verdant blooms. You can enjoy their flowers for a few weeks each year, so make the most of your time with them!
It’s important to note that dry air is bad for orchids, and can potentially be deadly. Mist them regularly and keep things at around 50% humidity to keep your orchids happy. They enjoy moderate to bright light, away from the direct heat of the sun. Indirect sunlight is what helps these orchids to bloom.
You should plant these orchids in a loose medium. Use an orchid mix that will allow proper aeration around the roots, repotting every several years. Keep your orchid’s soil evenly moist always, but not wet enough to create root rot.
During the growing season, you can opt to fertilize these plants two times a month using a good, organic, orchid fertilizer. You can also propagate them by division. Tropical lady’s slipper orchids grow best in USDA zones 3 through 7.
Scientific name: Tulipa
Tulips are some of the most popular flowers all over the world, prized for their beauty and the wide range of colors they come in. Did you know that tulips can also come in green? We find that this color of tulip is oddly striking in its subtlety. It doesn’t take much to appreciate them. Tulips are pretty sturdy plants that should be planted in the fall for a bloom in the late spring.
Since they are hardy and easy to grow, even novice gardeners will be able to enjoy planting green tulips. Green tulips can grow up to 15 or so inches tall. You can expect them to be beautiful in your garden, especially when combined with other flowers as companion plants.
They enjoy full sun the best, as this allows for good flowering. If you live somewhere especially hot, simply give them some shade in the afternoons. Tulips love rich, fertile soil, so be sure to mix in some compost when planting them. Keep the beds at medium moisture, and ensure good drainage to prevent rot.
Green tulips add whimsical beauty to bouquets when used as cut flowers. You can plant them in the fall and expect flowers in the springtime. Tulips grow best in USDA hardiness zones 3 through 8.
Scientific name: Zinnia elegans
The final green flower on our list is the spectacular zinnia, which is both beautiful and easy to grow. Zinnias come in a wide array of colors, and green is one of them. They love the warmth of summertime and will provide splendid blooms for you to enjoy from late spring through to the first frost of the year. It’s also worth noting that they are annuals pretty much everywhere you plant them, so enjoy them while you can!
Zinnias love the sun, so be sure to give them a spot that gets a lot of great sunshine. Not only will this give you amazing blooms throughout the flowering period, but it also keeps mold and mildew away, since the leaves are drier in the sun. Being easy to grow, zinnias aren’t picky about where they are planted. They only really require soil that has good drainage in order to prevent rot. They’re fine even in poor soils, though you can opt to add compost to enrich them.
What’s truly fantastic about zinnias is that they don’t particularly care about how hot it gets; they will simply bloom regardless. Feed them with fertilizer occasionally if you’d like to see more blooms, but they won’t need it in most cases. They are happiest when grown in USDA hardiness zones 2 through 11.
