Cold Climate Gardening

Inspiring Ideas and Photos Take the Autumn Garden to the Next Level
I’d read several books by Piet Oudolf and by Wolfgang Oehme, but I never really “got” the fall garden until I read Fallscaping, by Nancy Ondra and Stephanie Cohen. Somehow those two American women made gardening in the fall accessible to me in a way that those two foreign-born men did not.

This doesn’t really surprise me, as I was impressed with how down-to-earth and practical The Perennial Gardener’s Design Primer, their first collaboration, was. They leave no class of plant behind in their quest to help you maximize the beauty from your fall garden, and provide you with dozens of design strategies. And if their words don’t convince you, the photographs by Rob Cardillo will totally wow you. Take a look at this combination of pink muhly grass (Muhlenbergia capillaris) and Arkansas bluestar (Amsonia hubrichtii).

Sunday, October 8th, was a gorgeous autumn day, sunny and warm. I decided to go up the hill for a walk in the woods, camera in hand, and you get to share the results. (Be forewarned: this is an even longer than usual post.) But first, a little bit about where we’re going. Our family lives on 14 acres. It is a narrow slice of hillside, with our house near the road at the bottom of the hill and our land going uphill for about half a mile. Once upon a time, it was all forest. We figure our house was built sometime in the 1880s, so that’s probably about the time the trees were cleared for pasture, though it’s always been marginal land for grazing: not especially fertile acid clay, with a high water table that leaves many areas soggy during years of average rainfall. The forest has been growing back as the occupant before us (and maybe the one before him) gradually stopped mowing the areas furthest away from the house, though we still have a field of about 4 to 5 acres.

The field gets mowed yearly with a brush mower, which is also used to keep paths through the woods cleared enough so a suburban girl like me can pick her way without carrying a machete or getting lost. The path starts out in what I call the Secret Garden, which is an area closer to the house that reverted to trees early because it’s clearly too wet to mow. I have dreams of turning it into a native plant garden, but for now, that’s mostly all it is, an idea that, maybe someday . . . After meandering through the Secret Garden, the path starts going up, and threads through the hedgerow alongside the field before joining the woods proper.

Don’t these berries look ornamental? And the birds love them. Such is the recipe for disaster, for these are rose hips of the invasive Rosa multiflora. This shrub is growing on the bank of the seasonal brook that borders the northern side of our property, right before it narrows and becomes easy to cross at the top of a hill. As you cross the brook at this point, you can look back down the slope and watch the water spill over the rocks. I used to dream of sitting on a bridge and enjoying the view, which I would enhance with ferns and native flowers planted into the steep bank. But it took a mere decade for this little glen to fill up with the thorn-infested brambles, which I’ll have to remove before I can ever realize my dream, and I’ll have to be eternally vigilant ever after. Don of An Iowa Garden has been working on eradicating this shrub, and it sounds exhausting.

This is a section of the Birthday Garden, which is a somewhat raised bed sandwiched between the driveway and the house. At the base of the stone wall, looking rather pale, are some Colchicum byzantinum. Above them is an unknown chrysanthemum, which Debi Lampman of Bedlam Gardens in King Ferry, NY gave to me this spring, when I visited her in the course of researching an article on gardening hotspots in Ithaca. Next to the mum, Colchicum ‘Lilac Wonder’ emerges from the blue-green foliage of a catmint (Nepeta sp.). I got it from Bluestone Perennials as ‘Six Hills Giant,’ but it has never …

No, it’s not the Invasion of the Subterranean Aliens. These are emerging colchicum flowers. Col-chi-what? An underused flowering bulb from the Lily family, which hold a fascination for me that I really can’t explain. I never would have discovered them, had they not been growing here when we moved in. Their botanical weirdness of blooming leafless in the fall with a tube of petal-like tissue passing for a stem, while their leaves and seedpods are a spring-only event, is certainly part of the attraction. Locating new varieties is also part of the fun, similar to scoring a find at a flea market.

But part of the enjoyment of them …

This is my first colchicum of the year. It appears the Bookish Gardener beat me, as she is displaying a whole clump to my single blossom. To my eye, they are the same plant: Colchicum byzantinum. To your eye, the colors of the two flowers are different; her image is more accurate. Also, you can’t see inside my flower, but eventually it will look like her photograph. That’s how all my byzantinums look on the inside. For those of you unfamiliar with this genus, I suggest you browse through the Colchicum category linked on the sidebar. I’m afraid I won’t have time …

Some of you may recall that my first acquistion of Colchicum byzantinum ‘Album’ was an impostor. This beauty is undoubtedly the real thing. Not only is it white, but it has the same structure of petals and general floriferous character of the species. I just received and planted this earlier this autumn from Odyssey Bulbs, and it bloomed like a well-established clump. I had thought the first photo was as good as it was going to get, but I was pleasantly surprised. Whoever edited the Colchicum species …

Russell Stafford of Odyssey Bulbs describes this as “a superior selection whose rich violet flowers are among the deepest in hue of any colchicum’s. . . . It is of robust constitution.” Well, it does seem robust, but not any deeper in color than say, ‘Zephyr.’ It seems like color is such a moving target. Two different people can describe the same flower with two different colors. It makes it very difficult to feel confident that I have a correctly labelled plant. Stafford doesn’t mention a purple perianth tube, but this has one, did you notice?
