What do these mean?



This popular iris is encountered in coastally-effected settings from Oregon to Santa Barbara. Its dark green, grass-like leaves form an expanding clump to about eighteen inches. The spring flowers are generally a deep violet, but naturally range from white to yellow to lavender all the way to purple. Since commercially grown plants come from seed, the flower color will vary from plant to plant. Like all irises, Douglas iris will spread by offset to form a large clump. After several years the patch can be lifted, divided and re-planted in the winter time. This will reinvigorate the planting and facilitate better flowering. Douglas iris responds well to regular watering but becomes fairly drought tolerant after the plant is established.
