We live on the Oregon coast (U.S.) where the small orange and the large red mostly grows in gardens and along roadsides. I grow the large red. I began with 6 corms 4 years ago and now I have about 80 plants! This year I am thinning drastically as it's taken over my beds. Our climate here is cool and moist so I don't have to water much. During the flowering season I water lightly every 2 weeks. It grows in any soil from sand to heavy mulch. However, in the Willamette Valley where temperatures soar into the 90s in the summer it has to be grown in semi shade to mottled light and watered frequently. It's a wonderful plant for naturalizing along streams and creek beds. I have found it does not do well in containers but perhaps others have better luck? Hummingbirds love the red flowers and feed from it continuously while in bloom. Along the coast it blooms from July through late August, perfect timing for the hummingbird migration. I affectionately refer to it as the Bird of Oregon because of it's distinctive shape (much like a smaller Bird of Paradise). This is one of my favorite plants and every year I look forward with anticipation for it to open up and spread its wings.
