Gro-Low' sumac (Rhus aromatica): not poisonous in the least. Grow it for its glossy blue-green leaves, buttery-yellow spring flowers, fuzzy red fruit in late summer and fire-engine-crimson fall color. This plant is one tough cookie and grows great in shade, but it picks up steam faster with sun and heat
plumbago (Ceratostigma plumbaginoides: (zones 5 to 9) This plant grows well in sun and part shade in all kinds of conditions all over the U.S. It chokes out weeds, blooms in a clear blue that reflects the summer sky and tops it off with fantastic fall color.
