Imagine yourself next summer, the heat of July warming your face as you gaze across your garden, colorful perennials dot the landscape… but you’re thinking back to springtime, May, when your glorious Iris were in full bloom. Nothing compares… But wait! Consider this: a second bloom season for Iris. Yes, reblooming Iris hold the promise of reliving the spring time bloom in the middle of summer!
Scanning the summer garden, speckled with the hues of phlox, cone flowers, daisies, lilies and the like, my heart skips a beat as I catch sight of a Tall Bearded Iris! A delightful surprise in the midst of the late summer bloomers. It’s one thing to take in the wash of color in a garden full of Iris at peak bloom in May; it’s quite another to find a lone flag, so seemingly out of time and place, among the rudbekia!
As with any gift of nature, there are caveats. Reblooming Iris, while so satisfying when they produce bloom in July, August, September and even into October, do not bloom on command. Their remontancy is dependent upon multiple factors: soil conditions, weather, gardening practices, to name a few. Rebloomers need extra fertilizing (low in nitrogen, 5-10-10) and water compared to their single-bloom cousins. The plant’s own genetics, of course, play a strong role as well. Varieties of Iris that rebloom consistently here in the Willamette Valley (here is a partial list) may exhibit different behavior in other locales. Just as there are varieties of Iris that do not bloom every year in the spring bloom season, so is the case with summer re-bloom.
But when it all comes together… Wow! These bonus blossoms just scream to be united with pink and red lilies, flounces of phlox, fist-fulls of Black Eyed Susan (Rudbeckia) — anything blooming nearby. Rich summer bouquets can take shape before your eyes. Here are several of my favorites from a recent jaunt through the garden.
Pictured above a charming reblooming Dwarf Iris, Autumn Jester, cozies up to its little companion daisy. Wouldn’t this be lovely blooming among the snapdragons and pansies along a low summer border? Below, the pinks pack a punch. Peggy Sue mixes with the lovely lilies and echinacea for a sight so divine.
Pure As Gold mixes with Immortality, above, continuing the white-yellow theme carried by the daisies. The hosta leaf and blue thistles provide pleasing contrast to the bunch. “Cowslip” sneaks in a bit of summer informality….
Selecting the varieties of reblooming Iris for your garden which will be successful in your area of the country (or the world), is a matter of trial and error. The rebloom is a bonus. At the very least, you will enjoy one season of bloom in the springtime. Give it a try!
The Reblooming Iris Society offers a plethora of information on the development and care of Iris that rebloom. Start with their page offering tips for growing rebloomers, then explore the greater site for more information.
