Signs of Spring

At 7:44 AM on March 20 the Sun crossed the celestial equator heading north. In common parlance, that translates to: spring is here!

It didn’t take long for wildlife to answer the call. Two days later, I awoke to the sound of a red-breasted robin singing at 6:00 AM. The cardinals have been getting redder and redder and going great gangbusters for weeks with their impressions of distant car alarms, but they’re here year round. The robin was the first migrant I’d heard stretch its vocal cords this year.

While the robins celebrated spring by completing the last leg of their long journey, I was out in the garden performing one of the first jobs necessary to the season: uncovering my epimediums. (They have a common name—bishop’s hat—but somehow I just can’t bring myself to use it. They’ll always be epimediums to me.)

Along with hellebores and lungworts, epimediums start growing actively in March long before many of us have gotten out to remove the leaves that blew into the garden late last year after the rake had been put away for its long winter’s nap. (Or was it the gardener determined to nap? Tools can be convenient excuses…)

If you live on a lot with many trees, no matter how much you raked and blew last fall, you might find a lot of leaves staring up at you from the garden when the snow melts. Many plants can benefit from that cozy little coverlet, but for others it’s a problem.

While hellebores and lungworts are sturdy plants that can withstand the inevitable manhandling that occurs when you peel away sopping wet mats of oak leaves, epimediums are delicate little things with fragile stems all too easily snapped off. Wait even a week too long to clear them of leaf litter, and you may not be able to do it without surgical tools. (I exaggerate, but not by much.)

At left is a picture of a curled epimedium flower stalk taken on March 20 just after being uncovered. This happens to be a patch of E. ‘Silver Queen’, a large-flowered white variety. In just a few weeks, it will put on a display to rival the extravagant bloomer E. x youngianum ‘Niveum’ shown in the picture above.

As careful as I tried to be when I removed the errant leaves, I wasn’t careful enough. Below left is a photograph of a stalk that I clumsily damaged. It takes almost no force to snap the top off these little guys, and that’s one spray of flowers less for me, the bees and everyone else this spring.

Some epimediums have fairly persistent stalks that don’t disintegrate on their own over winter. While you might not have to groom ‘Niveum’ at all, most others aren’t as accommodating. E. x perralchicum ‘Frohnleiten’ has perhaps the most evergreen leaves of any epimedium. This is both a plus and a minus. In snowless winters, they’re something to look at. But snow or no snow, in spring they’ll require cleanup. A pair of hedge clippers is the tool for this task. They do the job quickly and with all the precision required. You could just leave last year’s foliage alone, and new growth would come up through it and eventually conceal it, but most epimediums look better with a figurative shower and shave.

Unless you mulched last autumn, have some light, compost-based mulch handy to spread on your epimediums as soon as you uncover them. Otherwise, the soil around them will dry out quickly. At this time of year the sun is surprisingly intense, although most of us aren’t aware of it because air temperatures haven’t climbed yet. But I’ve learned that when I come out of my winter semi-hibernation and start working outdoors up to eight hours a day in March and April, I’d better wear sunscreen! New growth of shade-loving plants should also have some protection, not from the sun itself, but from the soil dryness it can cause.

Of course, even if I didn’t remove the leaves from my epimediums, they’d grow right up through their brown blanket and bloom anyway. But I prefer the look of a clean bed with a dressing of compost as a nice backdrop. Knowing that the job of removing those leaves without damaging the epimediums becomes harder with each passing day is enough incentive for me to get outside in mid March no matter what the weather. Ironically, as intolerant as they are of mishandling, fresh new epimedium growth will have no problem withstanding freezing nights.
