4'H or Larger Perennials
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.
A new twist on an old favorite of ours, this new selection of the Single Red Confederate Rose or Terri's Pink Rose Mallow, Almost Eden' Baby Pink produces 6-8", medium pink flowers often marked with white especially early on in the day. This may be the longest flowering perennial Hibiscus that we know and starts flowering in late spring and lasts until fall. Easy, hardy, and reliable. Provide a protective winter mulch in zones 7A-8B. Item# 10397.
