Swamp Mallows from the Malvaceae family are shrubs with a perennial rootstock from moist spots in bogs in northern America. They require plenty of water in summer and are best cultivated in shallow water at the edge of a pond, where they will unfold willingly their large, tropical flowers from mid summer through early autumn.
Sow flat in spring at some 20°C in any humus rich, moist soil in a sunny spot. Transplant as soon as seedlings are strong enough. Give dormant rootstock in winter some protection from freezing through (e.g. mulch layer).
All are USDA Climate Zone 7.
20 seeds per package.
