Like a hollyhock on steroids, this beautiful plant has big, lush flowers and rich colors that visitors will notice right away. It's also known as bush mallow. Annual mallow comes in a variety of colors, including rich pinks and reds, as well as striking whites; many have a lovely veined pattern. It grows 2 to 3 feet high.
Things You'll Need
Fertilizers
Garden Stakes
Seeds
Watering Cans
Twine
Look for seedlings at your local nursery in the spring - starting with seedling is the easiest way to plant mallow.
Consider starting mallow from seed as an alternative. It's fairly easy, even for beginners.
Plant seedlings 10 to 12 inches apart in dry soil that's only moderately rich; plant after your region's last frost date.
Start seeds in peat pots indoors six to eight weeks before the last frost date. Transplant seedlings into garden after last frost.
Water only when soil becomes very dry.
Stake plants if they show signs of toppling. Simply take a wooden stake, drive it into the ground near the plant, and tie the plant to the stake with soft twine or plastic strips.
Pull plants out of the garden after the first frost.
Tips & Warnings
Annual mallow looks best planted in masses of 15 plants or more together.
Unlike some other forms of mallow, which are perennial and return year after year, annual mallow dies after just one year. However, annual mallow blooms for a longer stretch of the summer than perennial types.
Fertilizing should be done sparingly if at all; it can encourage too much foliar growth and less flowering.
