All gardeners and gardens live in the future and perhaps this one more than most because it is so large and so new. But the sight of these Alliums in the perennial border is starting to give some definition to the border.
Last fall I planted 150 Allium aflatunense and I think just about all of them came up. They are scattered among the hundreds of perennials I planted – and more to come – but it will be a few years before they give the effect they should: a perennial border with Alliums rather than an Allium border.
The perennials and grasses that will be 3’ – 5’ tall are 3” tall. So at the moment the Alliums aren’t exactly scattered “among” anything.
They need the perennials to give structure to the design. And they need the perennials to cover their dying leaves of course.
It is so nice to look out and see them.
Like Moliere’s Le Bourgeois Gentilhomme who discovered he had been using prose all his life…I have been doing succession planting all my life. But I only recently (a few years ago) read an article by the late Christopher Lloyd in which he named it.
What it describes is a way of having a succession of different plant ‘pictures’ in the same spot. So as one plant either dies down for the season, or finishes flowering, another plant in the same spot comes to the fore. Some common examples that most gardeners have seen or used are early Daffodils in the lawn, the Daffodils flowering in early spring, then disappearing as the lawn greens up; spring bulbs similarly can bring early color to the perennial border which then covers their dying leaves; early blooming sun loving plants can do well under the shade of deciduous trees – because the sun lovers get their needs fulfilled before the now-leafy trees shade the area.
Some examples I have used in past gardens (and may well use again). Heuchera ‘Palace Purple’ interplanted with Allium aflatunense. The rich, purple balls of the Allium flowers are lovely; but the leaves always turn brown at the tips and look weather-beaten even when they’re not. The Heuchera not only hides the unsightly leaves; the effect is as if the Allium flower is growing from the Heuchera leaves and the colors of the leaves and flowers complement each other wonderfully. Then by the time the Allium flowers are over, the Heuchera’s own creamy froth of flowers take over.
Glory of the Snow (Chionodoxa) interplanted with Siberian Iris and Japanese Anemone. The brilliant blue Chionodoxa bulbs make a better and better show as the years progress – and appear while the Irises are just beginning to come up in the early spring. Then the Iris leaves and the Anemone leaves) take over the area and cover the yellowing Chionodoxa leaves. The Irises begin to flower in June and after those flowers are over the area becomes( for a while ) a lovely contrast in green texture — tall slim Iris leaves and Maple-like Anemone leaves. Then by summer’s end the Anemones begin to flower until frost.
It takes some knowledge of various plants’ ‘schedules’, and yes, sometimes the planned succession doesn’t work out quite as well as it should. But when it does l it is so much fun to watch an area change – almost magically –over the weeks and months.
