What are Reblooming Flowers?
Reblooming plants are plants that produce more than one set of blooms in a growing season. This can occur naturally or as a result of specialized breeding. In nurseries and garden centers, plant tags will usually say reblooming or repeat bloomer on plant hybrids that rebloom. When in doubt, ask nursery workers about a plant’s blooming habits. Or, look up the specific variety online.
What Plants Rebloom?
There are far too many varieties of reblooming plants to name them all. Perennials have the most reblooming varieties, though many shrubs and vines are also rebloomers. For continual blooming roses, which are low maintenance repeat bloomers, go with:
Knockout roses Drift roses Flower Carpet roses Easy Elegance roses
Twist and Shout and Bloomstruck are two varieties of reliable reblooming hydrangeas in the Endless Summer series. Bloomerang is a beautiful reblooming variety of Korean dwarf lilacs. While the above-mentioned roses and hydrangeas continually bloom from spring to fall, Bloomerang lilac blooms first in spring, then a second time in late summer to fall. Honeysuckle vines and trumpet vines have flowers that bloom again. Certain varieties of clematis, like Jackmanii, have flowers that bloom more than once. Some annual and tropical vines will rebloom too. For example:
Morning glory Black-eyed Susan vine Mandevilla Bougainvillea
Though there are too many rebloomers to name them all, below is a short list of perennials that have flowers that bloom again:
Ice plant Yarrow Echinacea Rudbeckia Gaillardia Gaura Pincushion flower Salvia Russian Sage Catmint Beebalm Delphinium Icelandic poppies Astilbe Dianthus Tiger lily Asiatic lilies– specific varieties Oriental lilies– specific varieties Bleeding heart– Luxuriant Daylily– Stella D’Oro, Happy Returns, Little Grapette, Catherine Woodbery, Country Melody, Cherry Cheeks, and many more varieties. Iris– Mother Earth, Pagan Dance, Sugar Blues, Buckwheat, Immortality, Jennifer Rebecca, and many other varieties.
Flowers that bloom again do not require much extra care. To encourage reblooming, deadhead spent blooms. In midsummer, use a fertilizer with low nitrogen, like 5-10-5. This higher level of phosphorus promotes blooming. Too much nitrogen encourages only green, leafy foliage– not blooms.
