Start the Season with Early Blooming Iris

Dwarf Bearded Iris|Heather Carpet

Standard Dwarf Bearded Iris, Heather Carpet (Chapman, 1999), hugs  a garden path.

Easy to plant, easy to care for, easy to enjoy! That is the Iris. And such variety too! Variety of size, variety of bloom season, variety of color, variety of style. Isn’t success in life all about the choices we make? That simple maxim can apply to the realm of the flower garden too. The Iris offer such a host of choices, one is surely to find just the right color, or size, etc. Let’s talk about the breadth of bloom time, for example. The Miniature Dwarf Iris and the Standard Dwarf Iris are among the very first Iris to bloom. Weather depending, of course, they open up their diminutive blossoms (just 5 to 15 inches in height) approximately mid-March to early April (in most temperate zones), heralding the launch of another promising Iris season.

The Hungarian language has a saying, “The pepper corn is small, but mighty.” (Kicsi a bors, de erős). The same can be said about these Iris of smaller stature. They are no less hardy than their taller, more robust cousins. Dwarf Iris, both Miniature and Standard types, propagate with strength and, once in bloom, stand up to the early spring frosts. There are several wonderful resources available which provide great detail on the origins of these hybrids. The Dwarf Iris Society is a good place to start for further links and leads on exploring the subject. Several Iris breeders today have introduced spectacular Bearded Iris cultivars in miniature.

As spring widens its embrace upon the land, weep not for the fading Dwarf Iris, for the Intermediate, Median, or Border Iris are opening on the garden scene! A bit taller than the tallest Dwarf, yet shorter than the shortest Tall Bearded Iris, they offer brilliant bloom to span the gap between March and May, a beautiful complement to the Cherry blossoms! The earliest blooming Tall Bearded Iris will overlap with the later-blooming Intermediate Iris, to create a seamless floral transition of color. Sprinkle in several mid-season and late-season Tall Bearded Iris around your garden, and the color show continues well into June.

A few moments spent even casually mapping out the succession of Iris blooms in your garden will yield months of rainbow color from your ankles to above your hips! Dwarf, Intermediate, Tall Bearded, as well as Beardless Iris, are all planted in the summer months. Below is a simple chart, indicating approximate bloom times for Iris ranging from the Miniature Dwarf to the Tall Bearded, and including the Beardless Iris such as, Siberian and Louisiana. Bloom time is greatly dependent on weather conditions and gardening practices, however. For example, Reblooming Iris require regular fertilization and dividing.

If you are one who can hardly wait for the year’s Iris season to start, you have merely to plant some Dwarf Bearded Iris this summer. You will have Iris blooming with the first inkling of spring warmth. Even if you consider yourself simply a fan, a dabbler, a curious gardening newbie to the world of flowers, give the Dwarf Iris a try!

We’re trying a few new things

Last winter, during the long dark days, we pondered the spring. We asked ourselves, what could we offer to those lucky devils who live in warmer climes who were already up to their elbows in glorious warm soil by April? A few ideas took sprout, so to speak. Read on for more details.

There’s nothing like an iris.

Greetings fellow iris lover,
As a lover of plants yourself, you too understand the power of our gardens to transport us from the cares of the outside world. We’re drawn to the easy rhythms and satisfying pleasures of expectation and reward. You probably have found yourself contemplating whether to put a swath of blue iris – medium and light blues next to the peonies, and maybe some oranges, pinks and light yellows among the columbine…gradually we realize we’ve been at it for hours and the light is waning.

Take time to contemplate the garden design.

There is nothing like an iris, though, would you agree? Indisputably, they are the glory of spring. Artists have been fascinated by the exquisite architecture of bearded iris for centuries. And the colors! Heavens to Mergatroid! More colors than you can imagine, and then some… A not unusual reaction from a first-time visitor to our display garden at peak bloom in May, “Oh my! I can’t believe it! I never knew there were so many colors of iris!”

“Heaven to Mergatroid! So many colors!”

Here on the farm, as the season of iris bloom nears, anticipation steadily grows until the iris explode in a riot of wondrous color. Discovering new varieties, and marveling at incremental advances in breeding, makes each year just a little better than the last.

Eliciting “Wows” are not only the statuesque tall bearded displays, but also the rows of the early blooming Dwarf iris, which are more practical when space is limited.

A note of advice — if you live in the city, and desire solitude, don’t plant bearded iris in your front yard. Traffic will slow to a crawl. Passersby will exclaim, “I never knew there were so many colors of iris!” Plant the iris in the back instead, for a dreamy vista from the kitchen window…. And a quiet place to contemplate your garden design…

Where do you plant your iris? Front or back? What mix of perennials join your iris? Do you mix colors, or go with monochromatic designs? We’d love to hear from you!

By Kevin VaughnI grew up in Massachusetts in the AIS of the 60’s and when we went on tours the iris were not grown like a corn field but rather as a part of a garden picture. ‘Cup Race’ was one of the famous irises to come out of the Stedman Buttrick garden.Image courtesy of…

A small sampling of Siberian iris photos I’ve taken in years past showcasing the beauty they bring to the garden. Siberian irises make exceptional garden plants and are easy to grow and care for. They are especially beautiful when grown in large masses. For many decades the color range was limited, but recent…
