Hollyhock Colors: What Colors do Hollyhocks Bloom?
Curious wo know what colors your hollyhocks may bloom in if you plant them this season? These garden favorites can blossom in an assortment of different colors. In this article, gardening expert Paige Foley looks at the different hollyhock colors you can expect to see based on their variety.
Native to Asia, hollyhocks are known as a cottage garden staple. The dramatic height (from 3 to 8 feet tall!) and rainbow flower colors of hollyhocks add stunning dimension to any landscape. They have a large bloom window lasting from mid-summer to the first frost, and some varieties bloom in their first year.
With endless options to choose from, it may be daunting to choose the right hollyhock color and size for your space. There are several things to consider when choosing a variety. How tall do you prefer?
Do you want a single or double bloom? And the hardest choice, what color of flowers would you like to see? Here, we will discuss the different colors of hollyhocks to help narrow your search.
The Short Answer
Hollyhock comes in an array of colors, from white, red, pink, yellow and black. Yes, I said black. This is a rare flower color, which makes it a very popular choice. One of the only colors you won’t find is blue. Many seed companies sell packets of mixed varieties. If you can’t decide on one single color, mixed seed varieties are a great option.
The Long Answer
There are dozens of varieties of hollyhocks in every color of the rainbow except blue. You can spot them being grown along buildings, fences, flower beds, and in containers.
These dazzling flowers grow best in full sun with well-draining soils. However, they are very versatile and can also be grown in partial shade. The plants may be shorter in stature in shady areas and produce fewer blooms throughout the season.
