3-4'H Perennials

These taller perennials usually remain in the 3 to 4 feet high range under most conditions. Use them behind and among low to medium height growing perennials, as specimen plants, near the middle to the back of border, in front of medium and large shrubs and very tall perennials, and around larger tree form plants. Some of these will make nice container specimens and when used in combinations for large and very large containers. Growing conditions may affect the plant's ultimate size. This list may also include some tropicals that are grown as die-back perennials in zone 8B so just keep that in mind if you are in a colder climate.

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.
