Irises will bloom best in full sun, meaning at least 6 to 8 hours of sunlight per day. They can tolerate as little as half a day of sun, but it's not ideal. Without enough light, they won't bloom well. Bearded irises must not be shaded out by other plants; many do best in a special bed on their own.
Growing irises from bulbs is easy and provides some of the earliest blooms in the garden; later-flowering varieties compliment summer-flowering plants. Whether in containers or in the open garden, they are hardy and provide colour year after year.
Irises grow from underground bulbs or fleshy roots called rhizomes and, with proper care, the National Gardening Association says they'll regrow season after season in zones 3 though 8, or even zone 10 in dry climates.. . . . .364011236333!]0000000000000009783314146547!]
