April 2010 Plant Profile: Epimedium

April 1st, 2010 by Soest Gardener, Riz Reyes

It has taken me almost three years to get the chance to feature one of my most favorite of all blooming shade perennials and with a wide assortment of them beginning to hit their peak, I will discuss the entire genus. Known as” Barrenwort” to some, “Fairy Wings” to others and “Horny Goat Weed” to herbalist, I am talking about the enchanting Epimedium.

“Eppies”, as I often call them amongst fellow plant geeks, have long been known as a tried-and-true perennial for dry shade. Typically planted under trees in a woodland setting, we have a wide assortment of various species and selected cultivars that thrive in various conditions just to demonstrate how adaptive they can really be in many landscape settings here in the Pacific Northwest. With many recent introductions from China finding their way into the market, many unusual forms and hybrids are beginning to turn up.

Within the Soest Garden, we have about 10 different species and named cultivars on display. Most of them are evergreen and reside underneath a large red oak tree and a handful are deciduous that have evident buds ready to spring into full bloom in the month of April.

Every landscape deserves an Epimedium. You really can’t ask for a more elegant, tough and reliable perennial.

  • Common Name: Barrenwort, Fairy Wings
  • Location: Soest Garden Beds 2, 6, 7 and the dry shade bed under the large red oak. Two species in the Fragrance Garden (thought no Epimedium is fragrant, unfortunately)
  • Family: Berberidaceae
  • Origin: Asian and Eastern European species and some of garden origin
  • Height: 6-12″
  • Spread: Can form tight clumps after several years
  • Bloom Time: Usually mid-late March onto April and sometimes into May.
  • Bloom Type/Color: Various
  • Exposure: Part-Full Shade
  • Water/Soil: Well drained, moderately moist. Asian species and their hybrids tend to prefer more water.

CUH Update April 2010

April 1st, 2010 by Soest Gardener, Riz Reyes

April 2010

It’s finally beginning to feel like spring. Yes, we have our occasional bouts of cool temperatures that threaten the tender young growth steadily coming to the fore, but in true spring fashion, plants flaunt the floral frenzy that this season is known for. A new wave of spring flowering bulbs can be admired and adored here at CUH as they fill the air with their potent perfume. A mass of daffodils and fawn lilies take center-stage in the Fragrance Garden and the Daphnes are still going at it strong as they aren’t only blooming, but also pushing new vegetative growth for more blooms next season!

Nearby NHS Hall, we have a lovely, but often overlooked relative of the kiwi fruit, Akebia quinata ‘Alba’, that is so elegant and deliciously scented, no one really notices it. It is a vigorous deciduous vine (in very mild winters it can be semi-evergreen), but it is easily manageable.

In our efforts to promote and encourage research and education, a section of CUH grounds has been designated for a test plot we’ve referred to as the “Climate Change Garden”. Spear-headed by Prof. Soo-Hyung Kim, his graduate students and CUH grounds staff have begun to install beds that will feature genetically identical species selected for their biological responsiveness to temperature. Read more about it here.

Things are picking up momentum as I type so I’m eager to get outside and get on top of our cutting back and dive into some serious weeding. If we have a break in the weather, the Soest lawn is crying out for another haircut!

Ornamental grasses have begun to push their new growth so it’s time to get most of them cut back to allow them to develop. As always, we use our hedge trimmers to shear the grasses down to make the job go more quickly. Those trimmers are then put to use on the hedges themselves as our stunning Osmanthus delavayi also gets a haircut following their wonderfully scented white blooms.

April is also the month we turn on our irrigation system. In the next couple of weeks, the irrigation crew from UW Campus will meet with our irrigation specialist, Annie Billota, to check that heads are working properly and we cover the areas we need to be watered. We then set the frequency and just tweak it during the season as needed.

It is an absolutely great time to visit CUH as there’s so much to see, smell and admire. As many gardeners begin to brainstorm for their landscapes this year, our gardens are a wealth of ideas and fascinating plants!
