These ornamental grasses have a clumping or bunching growth habit. Though they do spread by an underground root, as all grasses do, they form new shoots at short intervals, so they do not wander outside of the area you want them to grow. These plants are all native to North America.

Is Zebra Grass invasive?
Zebra grass has invaded the Smokey Mountain National Park. The rangers are having a tough time controlling it.
Euonymus–burning bush–is very invasive in West Tennessee. I dug up and destroyed the two I had planted. Birds eat the berries, the seeds of which pass through their digestive tracts unharmed. Ranks right up there with honeysuckle and privet.
