Hollyhocks (Alcea rosea) are tall, short-lived perennial plants in many flower colors. Flowers can be single or doubled in whites, yellows, pinks, reds, and even the darkest burgundy that bloom from June through September. A member of the mallow family, hollyhocks are hardy between USDA plant hardiness zones 3 to 8. Our hardiness zone is 6.
Plan where you want to plant the hollyhocks. Hollyhocks need sunlight to thrive. You’ll want to find a place that protects them from the hottest afternoon sun while still giving them at least a half-day of direct sunlight. If you live where it is windy, find a place where there is a barrier to protect the tall, thick stalks from breaking. If you are not going to plant them near a wall or fence, select an area with enough space to be staked.
