From our guide

Village of the Hills

Tall shade perennial with broad leaves and flat white flower clusters in fall. After a hard freeze, sap splits the stems into ribbons of ice.

Why it works here

Major late-season nectar for monarchs, in shade where fall bloom is otherwise scarce. The ice formation is a genuine winter event.

Watch out

Tall and coarse — site it toward the back. Reseeds readily.
