If you've grown "Margarita," the chartreuse-leaved sweet potato vine, or the Sunlover coleus series, you can thank Allan Armitage, professor at the University of Georgia at Athens for introducing them to the garden trade.
Armitage is the author of several gardening books, including the newly revised "Armitage's Garden Perennials" (Timber Press). This detailed reference book, sprinkled with a little plant history, suggestions for plant combinations and the author's quirky humor, covers more than 1,250 of the best perennials, including garden mainstays and new introductions, along with zone hardiness and cultural recommendations.
"I can't write about this stuff without growing it," says Armitage, who has evaluated perennials in Montreal, East Lansing, Mich., and Athens, Ga., where he oversees the university's research gardens, evaluating new plants from flower breeders around the world.
Q: With so many new plants, how did you decide what went into this edition?
A: As I was writing the book, a dozen new cultivars of echinacea (coneflower) and epimedium were hitting the trial garden. The new cultivars tend to push out the older ones, but I didn't want to throw out all the old plants that were still good. For example, I still recommend some of the older coreopsis, like "Zagreb," which is spectacular.
And "Goldsturm" rudbeckia, which is planted at just about every corner gas station — it's one of those plants with staying power that I couldn't drop. The rudbeckias in general are great, and there are a lot of newer ones that are very nice, like "Herbstonne" and the taller "Henry Eilers," a Rudbeckia subtomentosa, which has very narrow petals and is an attractive plant.
Q: What's a workhorse perennial for full sun?
A: False indigo (Baptisia) is definitely on my list. It's a native plant that, once established, is a consistent performer that will persist for 20 years or more. There are at least a half-dozen colors and new hybrids, and more are coming. It's really a classic perennial that grows 3 to 4 feet tall and wide and has few insect or disease problems. However, it's a plant that has very little joy in the retail setting because it looks like a stick in a container, so few people know what it has to offer.
I'm also enamored with hardy hibiscus this year. There are so many fine (hibiscus) out there, and breeders are working on some so they're more compact at 3 to 4 feet tall. "Cranberry Crush" is a good example at 3 feet tall and wide with bright rosy-red flowers. It's reliable year after year.
Q: What's your favorite for shade?
A: Well, that could change tomorrow, but today it's epimedium. There are so many to choose from. They have handsome flowers in spring, they're drought-tolerant and they make a great ground cover. Pulmonarias are a big deal for the shade garden too. They've been around a long time and they've got really handsome foliage. Hellebores, too, are definitely one of the ones I love for shade. They have always been good plants, but the flowers were hard to see. "Ivory Prince" was the first with upward facing flowers and there's "Pink Frost," both very good. They just may be hard to find. And Northern maidenhair fern — you can't do much better than that in the ferns.
Q: You recently moved into a smaller house with a much smaller garden. How are you whittling down?
A: I had a spectacular garden at the old house and was growing a lot of tiarellas, lungwort and other shade plants, but this new garden is tiny and has more sun. The "before" was pretty awful but it's been fun — I stuff things in. I have absolutely no design in my yard, but I know enough about plants to know what they need and where to place them. The new place is already overrun. That's what gardening is about. Don't take it too seriously — it should be a pleasure, not a pain.
