Landscaping Tips: Hollyhocks are drought resistant, making them excellent plants for the tough-to-garden sunny spots in your yard. Remember that hollyhocks may require staking if planted in an open area, so consider planting near a sunny wall or fence.
Plant hollyhocks 1 1/2 to 2 feet apart.
Hollyhocks have a short blooming period, which can be extended by removing dead flowers as soon as they are spent.
Most varieties of hollyhocks live only two to three seasons. However, hollyhocks reseed themselves annually. So, you will likely have hollyhocks for years after the original plants have died.
