Where To Find

Scattered statewide, in cultivation.

A nonwoody shrub, it dies back to the ground every winter. People who cultivate it typically trim it to the ground in late winter or early spring. It tolerates drought and erosion and will grow on very harsh sites in average soil and full sun.

This plant, introduced from Asia, has been used for erosion control in road construction. Its arching, fountainlike habit and often spectacular late summer blooms make it a popular landscaping shrub for sunny areas. It can reseed itself and also forms new plants where stems touch the ground.

As with many other exotic imported plants that can naturalize, this plant can become weedy in some areas. In New Jersey, it has been declared an invasive plant. This is one reason we encourage people to use native plants in landscaping.

About Wildflowers, Grasses and Other Nonwoody Plants in Missouri
A very simple way of thinking about the green world is to divide the vascular plants into two groups: woody and nonwoody (or herbaceous). But this is an artificial division; many plant families include some species that are woody and some that are not. The diversity of nonwoody vascular plants is staggering! Think of all the ferns, grasses, sedges, lilies, peas, sunflowers, nightshades, milkweeds, mustards, mints, and mallows — weeds and wildflowers — and many more!
