The show starts off with a bang in early spring when the fabulous foliage of this iris bursts forth heavily colored deep violet. The fans are very striking and the color rises quite high on them making it really stand out. In May the deep blackish bloom stalks emerge and rise to produce a profusion of small, flaring flowers in a lovely shade of medium blue-violet with bright yellow signals. The buds and blooms are profuse and a clump at its peak is like a cloud of butterflies.
This water loving iris can reach to six feet in ideal conditions, but rarely gets taller than three and a half feet for me, as our soil is very lean. It is happiest in moist soil but does just fine in regular garden conditions, where the rhizomes appreciate a good composty mulch. After the flowers finish, the foliage color fades to green in summers heat, while the seedpods swell and float like little green balloons over the gracefully arching fans. Most species crosses are sterile but 'Gerald Darby' usually produces abundant seed here, tho I have never tried to germinate them.
'Gerald Darby' is an iris that, thru the test of time, has really proven itself to be a fantastic addition to most any garden. It is terrifically hardy and can be successfully grown from Zones 4 to 9. A vigorous grower as well, it quickly makes a beautiful clump. You can purchase it from commercial growers who specialize in beardless irises and also those that offer pond plants. Try it, you'll like it.
