Light

Full sun. In shade it leans.

Water

Likes steady moisture. Water in dry spells, especially the first year.

Planting and soil

Plant in spring or early fall, crown level with the soil.

Feeding

None. Rich soil makes it even taller and floppier.

Pruning

Optional early-June pinch by half. Cut stems down in late fall or early spring.

Through the year

Big basal leaves in spring. Tall stems by July. Flowers August to September.

If something's off

Leans or flops in shade or rich soil. Spreads slowly by roots; divide every few years.

Plays well with

Plant it with friends.
