Hollyhocks are native to China, but they make a splash in gardens all over the US with their tall flowering stalks. Most varieties of hollyhock are hardy through USDA zones 3 to 8, so they can handle varying degrees of weather. Hollyhocks are true biennials, meaning they grow only for 2 years before they die. However, hollyhocks can be planted as annuals and some can even survive as perennials for a short time.
Choose a spot in your yard for the hollyhocks. Hollyhocks like full sun and well-drained soil, although they can handle many soil types as long as they are moist.
Plant hollyhocks in the spring after the last frost. The seedlings need not be very tall, only a few inches, when you set them out.
Dig holes for the hollyhocks. Make sure the holes are as deep as the container the hollyhocks are growing in and twice as wide. Space each hole 4 to 5 inches apart.
Place the hollyhocks in the holes. Fill the holes with soil and pat it down firmly.
Water the hollyhocks for 3 to 5 minutes.
