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.

 

 

Dense clusters of large pink tubular flowers with a white lower lip are born in late summer and early fall on this easy native perennial. Excellent for attracting bees. This is the latest flowering Physostegia that we grow. The Fall Obedient Plant will readily spread by rhizomes creating a mass of sturdy, 3-4' stems. An easy and reliable native perennial.

The fountaining clumps of large, dark burgundy to near black, 1"+ wide, sword shaped foliage makes an outstanding accent or backdrop for smaller growing perennials in the summer and fall garden and landscape. First Knight™ Hybrid Purple Fountain Grass, a trispecific seed sterile hybrid Pennisetum, was developed and selected for its exceptionally dark foliage color, vigor, disease resistance, and zone 8 cold hardiness.
