Common Mallow
Malva sylvestris
An herbaceous plant featuring rounded to lobed leaves with serrated margins, prominent veins, and a soft, slightly hairy texture on upright stems.
- Light
- Full sun to partial shade, requiring at least 6 hours of direct sunlight daily for optimal development.
- Water
- Water moderately when the top inch of soil feels dry. Established plants display moderate drought tolerance, though prolonged dryness can stunt growth.
- Growth
- An herbaceous annual or perennial plant forming an upright or spreading clump, reaching heights of 2 to 4 feet with a spread of 1 to 2 feet, featuring a moderate growth rate.
Care instructions
Provide full sun to partial shade in well-draining soil. Water regularly during dry spells to maintain moderately moist soil, and apply a balanced, slow-release fertilizer in spring to support healthy vegetative growth.
