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.

How could this happen? After explaining to Zoey in the comments of this post what colchicums were, I realized I had never shown what the foliage looks like. It’s not exactly breathtaking, so I don’t have many photos of it to share. I had to scan in this photo, which was taken in my very first spring here (1990). I’m sure I took it with the hopes that I might someday be able to identify the foliage. You can see one clump of strap-like daffodil leaves, which are about full height, and the broader leaves of the colchicum leaves behind them. This should give you an idea of the scale of the foliage. Keep in mind the flowers are about the size of crocus blossoms. (As with almost all images on this blog, click on the small photo to get a much bigger one.)

Now this second photo is a bit more interesting.I don’t often get to see this, myself. It is the seed pod of the colchicum flowers that bloomed the previous autumn. This is why one supposedly common name of colchicums is Sons-Before-the-Fathers. In a calendar year, the seeds show up before the flowers do. This is because the ovary, the seed forming part of the flower, is actually located at the base of the perianth tube, just underground. The peri-what? you ask. What looks like the stem of the flower is actually a tube of petal-like tissue, and the seed making parts of the flower that in a rose, for example, would be right below the blossom, are actually in the bulb underground. The ovary, now containing the seeds, is brought above ground in the spring when the leaves emerge.
