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.

 

 

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.

Large clusters of rich purple to red-purple flowers sit atop the sturdy 3-4' stems of this medium sized Ironweed in summer and potentially into fall. Baldwin's or Western Ironweed, Vernonia baldwinii, is an excellent source of midsummer pollen and nectar for long-tongued bees, butterflies, and other pollinators. This species is more drought resistant than many Ironweeds once well-established and it is important to note that this species can colonize an area via long rhizomes. Its ability to colonize an area may make it a better choice for naturalistic areas like meadows, prairies, and roadsides than in more formal garden settings. Provide good drainage and a full sun to mostly sunny site with average moisture. Deadhead once flowering is complete to prevent unwanted seedlings. Item# 12356

Blackhawks Big Bluestem, Turkey Foot Grass

Andropogon gerardii 'Blackhawks' PP27949

One of the hottest new native grasses on the market! Blackhawks Big Bluestem starts off in spring as a deep green clump of upright to arching blades that may be tipped with red to purple. It is in late summer when the real show begins with the upright and arching foliage and flowering stems of August deepen to red to red-purple and further deepening and intensifying as the cooler fall weather arrives becoming nearly all black as its sturdy and showy flowering stems begin to mature. Blackhawks Big Bluestem is a slightly more compact plant reaching about 4-5' high when in flower. The species is native throughout much of the eastern 2/3's of the US and is a clumping to slowly spreading rhizomatous grass whose seeds are utilized by a number of seed eating birds. Provide a full to mostly sunny site with an average to well-drained, acidic soil for the deepest foliage colors and optimum vigor. Plants are in their best form when grown in a low fertility soil. Overly fertile soils can cause them to topple at maturity. Images courtesy of Brent Horvath, Intrinsic Perennials, all rights reserved. Item# 12169

Common Boneset is a clump-forming late summer to early fall flowering perennial native to much of the central and eastern US. The flowers attract a variety of smaller pollinators. The united pairs of leaves led herbalists to believe that this plant would help with broken bones.
