The listing, Black Cherry Hollyhock Seeds (Red/Black flowers) has ended.
Beautiful hollyhocks are easy to grow and really puts on a show in the yard. Hollyhocks can grow up to 9 feet in height, so they are best planted along buildings or fences and at the back of a flower garden. They are great flowers to use for hiding unsightly areas around the house. Plant hollyhocks in a location with full sunlight and rich soil for best growing conditions. Hollyhocks need to be staked if planted in locations with lots of wind.
Scatter seeds in the Spring where you want the hollyhocks to grow, preferably by a doorway, along a fence or at the back of a flowerbed. (Remember, hollyhocks are tall! And they don't transplant well, so be sure to sow them where you want them to grow.) Scatter in the fall for early Spring growth.
When temperatures reach anywhere from 59 to 68 degrees F, the seed will germinate; however, the resulting plants probably won't blossom for another year.
Hollyhocks require watering during hot, dry conditions, and will withstand moisture if the soil is well drained. Try to keep water off the leaves to prevent diseases. After flowers have died off, cut off that stalk at the base to promote regrowth. After the flowers have bloomed, in the second year for some hybrids, they will self seed, and should continue to produce more plants as the years pass.
Hollyhocks grow in zones 3 to 9, and respond well to treatment with a slow-release fertilizer in the second year.
