IBOUGHT MYSELF A WINTERHAZEL 20-ISH YEARS AGO, around the start of my Zone 5 gardening adventure, fresh in from the warmer city and with a lot to learn in the years of weekend gardening that lay ahead. The image of the massive old ones that grew at Wave Hill in New York City was firmly in my mind’s eye, and I was determined my Corylopsis spicata would be just like that some day: a cloud of yellow. “Some day” would be the operative words; this year, it finally was, at about 18 feet across and half as tall. And apparently I am not alone in this being my glory year.
The spike winterhazel (as C. spicata is known) is one member of this genus of witchhazel relatives that should be better grown, I think, even if their extra-early flowers can be iffy here. That gets it listed in many places as Zone 6-8, though it’s otherwise hardy to 5. I never really minded, because what followed the sometimes-half-strength bloom were pleated, bluish-green leaves (details in in the slideshow, below) so beautiful I never tired of them. And the plant’s structure, a slightly chaotic, outstretched tangle of delightfully crooked arms, pleased me all winter long. (That’s mine on the far left in the photo above, to show scale and shape, looking down the front path.)
But then came the spring of 2010, the jubilee. As the bloggers in Southwest England at the Hegarty Webber Partnership garden design site will tell you, too, there’s something going on this year with winterhazel. (I’m happy for such company in this fine moment, and also to discover their blog, which rates some clicking around; see you there.) Their 20-something-year-old plant went positively mad, too. Synchronicity!
Grow winterhazels in sun or part shade, in moist but well-drained soil, and if you’re pushing it (as I am) with the tassel-like flowers, offer a site that gives protection from winter winds that could kill some of those precious buds.
There are other good garden species, notably C. pauciflora (the buttercup winterhazel, Zone 6-8) and C. glabrescens (the hardiest, supposedly, Zone 5-8), and so on, but I’m a spicata girl through and through.
So much so that in this year of the winterhazel I treated myself to the gold-leaf form, C. spicata ‘Aurea,’ above, sometimes labeled ‘Gold Spring,’ and I have to say when the box arrived I could almost see it growing right through the corrugated walls. Happy days.
