The Iris it is hardy, reliable, and easy to grow. Irises also attract butterflies and make lovely cut flowers.
The distinctive flowers have three large outer petals called “falls” and three inner upright petals called “standards.” The falls
may have beards or crests. Bearded iris are so-called because they have soft hairs along the center of the falls. In crested
iris, the hairs form a comb or ridge.
Most irises flower in early summer. Some, mostly bearded hybrids, are remontant, flowering again later in the summer.
Irises need at least half a day of sun and well-drained soil. Without enough sun, they won't bloom.
They prefer fertile, neutral to slightly acidic soil. If your soil is very acidic, sweeten it with a bit of lime, and forbear summer
watering, which can lead to rot.
Bearded irises must not be shaded by other plants; many do best in a special bed on their own.
Soil drainage is very important. Loosen the soil with a tiller or garden fork to a depth of 12 to 15 inches, then mix in a 2- to 4-
inch layer of compost.
Plant iris in mid- to late summer.
Bearded irises have rhizomes (fleshy roots) that should be partially exposed, or thinly covered with soil in hot climates.
Plant rhizomes singly or in groups of three with the fans outermost, 1 to 2 feet apart, depending on the size.
Dig a shallow hole 10 inches in diameter and 4 inches deep. Make a ridge of soil down the middle and place the rhizome on
the ridge, spreading roots down both sides. Fill the hole with soil and firm it gently.
When planting, top-dress with a low-nitrogen fertilizer, and again in early sprin
Keep rhizomes exposed. Unlike bulbs, which thrive deep underground, iris rhizomes need a bit of sun and air to dry them out.
If they're covered with soil or crowded by other plants, they'll rot. Irises may benefit from shallow mulching in the spring.
Don't trim iris leaves. Leaves carry on photosynthesis for next year's growth. Cut off brown tips—and cut the flowering stalk
down to the rhizome to discourage rot.
If iris foliage is hit with heavy frost, remove and destroy it to eliminate borer eggs.
After 2 to 5 years, when clumps become congested or lose vitality, divide and replant sound rhizomes in fresh soil. The best
time to replant irises is soon after bloom. Transplant them to places where they will have “wet feet but dry knees
Irises are deer-resistant and drought-tolerant. However, they are susceptible to borers, so check the rhizomes (fleshy roots)
yearly for holes, discarding any infested ones.
Verbena bud moth, whiteflies, iris weevil, thrips, slugs and snails, aphids, and nematodes may also be troublesome
