Perennials Over 4'H

The very tallest perennials that commonly exceed 4 feet high under most conditions. These very tall, often statement making perennials are well suited to use at the back of the border and in front of medium to large shrubs and taller tree form plants. Some may be suitable for large to very large containers as specimens and thrillers. Growing conditions may affect ultimate size. This list also includes some tropicals/subtropicals that are grown as die-back perennials in zone 8B/9A like Angel's Trumpets, so just keep that in mind if you are in a colder climate.

 

 

Willowleaf Aster, Willow Aster

Symphyotrichum praealtum, Aster praealtus, Aster caerulescens

The tall stems of this native perennial cover up in 1" light purple daisies in late summer and fall. Willowleaf Aster, Symphyotrichum praealtum, produces a multitude of upright to arching stems once well-established and makes a grand statement in the fall garden, prairie, meadow, or roadsides.
