Douglas Iris, Iris douglasiana is a knee high perennial with
rhizomes that spread slowly into a 2 to 4 ft wide clump. The flowers
arise on a 1 to 2 ft high stem, are cream to light purple and three inches
wide. Douglas Iris is native from Santa Barbara to Oregon and likes
full sun near coast, afternoon shade inland, some summer water. Fast
growing near the coast, but slow inland. This iris prefers richer
soils, such as clay, with organic matter, and is not happy here when
the winters are cold(snow) and the soil gravelly. Does fabulous in the
runoff of buildings. That little ditch that the water runs down the the
street in is a perfect place for Iris. No rain gutters, plant Douglas
Iris.

Zauschneria and

Roderick to make a really cool planter bed.
