The flowering stalks of the hollyhock, Alcea rosea, are covered in buds from the top all the way down to the rosette of foliage at the base. Once they are fully grown and ready to burst into color, these blooms start at the bottom and slowly work their way up, unfurling a little at a time. As the blooms continue to open, there will typically be several blooms per stalk all opening at once to create beautiful columns of rainbow-worthy color.
Growing hollyhocks (Alcea rosea) in the garden is the goal of many gardeners who remember these impressive flowers from their youth. The flower stalks on hollyhocks can reach heights of 9 feet tall! They can tower above a garden, adding a lovely vertical element to your yard. Let’s look at a few tips on hollyhocks to help you grow them in your yard. How to Plant Hollyhocks The first thing to understand is how to plant hollyhocks. Hollyhocks need full sun and moist, rich, well drained soil. The mistake many novice hollyhock growers make is to plant this flower in soil that is too dry
First of all, hollyhocks are a short lived perennial. This means that most varieties will only live two to three years. Their lifespan can be extended some by removing growing hollyhock flowers as soon as they fade. If you live in a non-tropical region, cutting them back to the ground and mulching them will also help. The one benefit that comes from growing hollyhock flowers is that they easily reseed themselves. While they may be short lived, in their proper growing conditions they will continually grow more, which will keep the hollyhock flowers consistent in years to come.
