While Waiting for Winter


While my back was turned (okay, I was out of town), we got a little frost. I didn’t realize it until I walked around my garden yesterday and discovered that the New Guinea impatiens, coleus and zinnia had collapsed. The dahlias also had gotten zapped. The cannas, however, were still standing tall in their pots, and I’m going to leave them there until the frost makes a repeat performance.

Losing annuals is to be expected. But what really caught my eye were the flowering plants that were looking so fresh that you might have thought it was June. ‘Indigo Spires’ salvia, for example. It’s a 6-foot tall plant with 12-inch deep royal blue flower spikes, and next year, if I have any smarts, I will have a lot of tall stakes so my three plants will no longer need to get support by leaning against a nearby boxwood. (Santa Claus, are you listening?)

Also helping to hold up the salvias is a ‘Lady Elsie Mae’ rose. This shrub is a marvel, brimming with salmon-pink double flowers from the moment it breaks dormancy until the end of November—or later. No disease or pest problems, ever. Oh sure, it gets nibbled by Japanese beetles now and then, but nothing that can’t be managed as long as you’re not squeamish about squishing. This is a low-maintenance rose.

But what really surprised me was the calamintha. Last year at the Lurie Garden’s plant sale I bought this Calamintha nepeta subsp. nepeta (I know, it’s a mouthful) since it’s a real bee magnet and we need to provide help for bees whenever we can. As it grew this year, I noticed that its flowers really do have a lavender tint to them, although from a distance you would probably call the flowers white.

Calamint

Whatever you call them, as we move into November, they are blooming their little heads off, full steam ahead. And if you run your hands along the stems, they will give you a lovely whiff of mint. To read more, check out our September/October issue in which Nina Koziol wrote about calamint.

questions

I have read that purple coneflowers (Echinacea) are a good source of food for birds in the winter. Will they be okay if not trimmed back until spring? If so, how early should they be trimmed?

My Siberian iris ‘Gracilis’ plants have only one bloom per clump. I have five 3 to 5 year-old clumps that are 8 to 10 inches wide. They do not appear to be crowded. All are planted in a moist area. Why is there only one bloom per clump?

Our Russian sage (Perovskia) is full and bountiful but will not stay upright. Is there anything we can do? Is there a way to split some off when it has outgrown its space? Should it be trimmed back in fall or spring?
