Gardeners' Notes:

Doesn't seed itself as freely as some other Malvas. Very pretty flower. Blooms June-October in my garden.

Makes a nice cut flower. Once it starts going to seed, though, you either have lots of brown pods spoiling the looks or a hacked back plant, which isn't real attractive either. But it's so awesome in bloom (I love that shell pink) we'll forgive its shortcomings.

Neutral poppysue On Mar 18, 2002, poppysue from Westbrook, ME (Zone 5a) wrote:

Hollyhock mallow is a bushy perennial, with slightly downy foliage and grows 2-3 feet tall. From mid-summer on it produces pale pink or white flowers 2-inches across. Plants tend to be short lived and may die out after 3 or 4 years in the garden but it often leaves behind self sown seedlings that can be lifted and relocated. Plants prefer well-drained soil in full sun but in hot climates afternoon shade is recommended.
