Iris douglasiana (Douglas Iris) - This California native perennial is a vigorous growing plant that forms 18 inch tall by 36 inch or more wide clumps of arching, evergreen leaves. The lavender-blue to near white flowers appear in spring on 1 to 2 foot tall branched or unbranched stems. Our form is entirely pale blue. Plant in full sun to light shade on the coast and light shade inland with occasional water. It is hardy to <15 degrees F. Has an extensive natural range along the coast from Santa Barbara to Oregon. It was named for David Douglas who collected it around 1830 in Monterey County.
The information that is presented on this page is based on research we have conducted about this plant in our library and from reliable online sources. We also consider observations we have made of it in the nursery's garden and in other gardens we have visited, as well how it performs in our nursery crops out in the field. We incorporate comments that we receive from others as well and welcome getting feedback from anyone who may have additional information, particularly if they know of cultural information that would aid others in growing Iris douglasiana. |
