Iris douglasiana (Douglas Iris)
A fine evergreen Iris, this plant reaches 1-2 tall with a 3 flower.
In spring, the flowers range from lavender to violet and are framed by broad leaves.
Douglas Iris is found on dry, grassy slopes and brush lands only between southern Oregon and central California.
However, it is hardy from USDA zones 5-10. It grows well in either sun or shade and with little care will spread to form a 2-4 clump.
Being easy to grow and extremely long-lived (clumps have been found in the wild that are over 100 years old), the Douglas Iris should be in every native plant garden.
Some sources describe this iris as an aggressive weed as livestock will not graze it should we be so lucky to have this gorgeous native assert itself in our meadows!!
