Hardy hibiscus with large rosy-lilac flowers with a dark crimson center over deep green leaves

Light

Full sun. Fewer flowers and weaker stems in shade.

Water

Likes steady moisture and handles wet soil. Water deeply in dry spells; wilting is its way of asking.

Planting and soil

Plant in spring or early summer in rich soil, crown level with the surface.

Feeding

Compost or a balanced slow-release feed in late spring when shoots appear.

Pruning

Cut the dead stems to 4–6 in. in late fall or early spring. Each flower lasts a day; no deadheading needed.

Through the year

Shoots emerge late May. Buds by July. Flowers July to September. Dies back with frost.

If something's off

Japanese beetles and hibiscus sawfly larvae chew the leaves; hand-pick or hose them off. Don't assume it died over winter until June.

Plays well with

Plant it with friends.
