View some of the best reblooming iris varieties and learn about growing these season-extending flowers.
This midseason iris reaches about 30 inches tall and is one of the most reliable rebloomers, producing a second crop of flowers in the fall.
Tip: Like standard irises, rebloomers are classified by their season of spring bloom, from early to late season. In addition to the first bloom, rebloomers will flower again after rest period, usually in the fall.
'Jennifer Rebecca' grows about 34 inches tall and is a midseason bloomer.
Tip: Plant rebloomers a little closer together than standard varieties -- about 12 to 16 inches apart.
'Buckwheat' grows about 36 inches tall and is a midseason iris.
Tip: Because they must produce two (or more) crops of flowers each year, reblooming irises should be fertilized both in spring and fall, as growth starts to speed up.
This mid- to late-season beauty reaches 36 inches.
Tip: Unlike standard irises, rebloomers should not be allowed to dry out in summer. Keep the soil evenly moist, but avoid getting the leaves wet.
'Harvest of Memories' is a midseason bloomer that grows about 40 inches tall.
Tip: Not all reblooming iris will produce a second flush of bloom each year. Chances for a second bloom are best for plants that are at least a year old and in USDA Zones 5-8.
This bicolor rebloomer is a midseason variety that grows to 36 inches.
Tip: The best time to divide reblooming iris is in the fall before flowering starts. Break or cut off the outermost rhizomes, but leave a substantial center core to ensure bloom the next year.
This 30-inch tall reblooming iris has a very long season of bloom in spring, then reblooms in late summer.
Tip: Most rebloomers are tall bearded iris, but other types -- such as dwarf bearded, Japanese iris, and Siberian iris -- can also rebloom. You'll probably need to seek out a specialty iris grower to obtain these varieties.
'Rosalie Figge' is a late-season bloomer that grows 36 inches tall.
Tip: Like other rhizome-producing irises, rebloomers require shallow planting. Set the rhizome no more than 1 inch into the soil; ideally, about the top quarter of the rhizome will still be visible after planting.
'Best Bet' is an early-season iris that grows 36 inches tall.
Tip: Irises prefer fertilizer that is low in nitrogen. Look for a fertilizer where the first number is lower than the others. For example, 5-10-10 or 3-10-20.
This iris blooms early to midseason and grows to 34 inches.
Tip: When dividing irises, check rhizomes for softness, which is a size of disease or insect damage. Discard any rhizomes that are not firm and plump, or that don't have fan of leaves.
'Autumn Tryst' is an early to midseason bloomer that reaches 34 inches.
Tip: Cut back iris leaves to 3-4 inches after a frost to lower the chances that insects or fungal spores will overwinter in the foliage.
This is an early bloomer that grows 33 inches tall.
Tip: Although most rebloomers flower again in the fall, others rebloom in late spring or summer. In some cases, they may produce three or more flushes of bloom.
