The Bright Side of the Blizzard

According to weather guru Paul Douglas, the blizzard that paralyzed the southern half of Minnesota and Wisconsin yesterday dumped 11.5 inches of snow on Northfield by 5 p.m. Saturday. My hunch (and my sore back!) suggest it might have been a bit more than that, or at least, we had enough drifting to make it feel like a lot more than that. But, there is a definite bright side to this blizzard. The plants — especially the USDA zone 5 butterfly bush that I’m hoping to get through the winter — are well insulated.

Snow serves the same purpose as mulch, only it removes itself in the spring. Once the ground is frozen (no problem here!) snow cover keeps temperatures consistent, so rather than thawing on warmer days and then re-freezing on colder ones, the plants will stay consistently cool and dormant through the winter. The chances of plants heaving out of the ground in thaw-freeze cycles are also reduced.

Because an earlier effort to growing butterfly bush did not work out, I planted two bushes in pots last spring and one in the ground near the house. They grew well and all of the plants flowered, but I’m hoping to help them get bigger. I fell in love with the large butterfly bushes I saw on garden tours in Buffalo, N.Y., last summer. The two pots are in the garage and, I hope, will survive the winter well there. The one in the ground is — thanks to the blizzard — under 2-1/2 to 3 feet of snow.

Only time will tell how this winter turns out, but for now, my plants are cozy under a very thick blanket of snow.

Fall Color Combos

This past weekend, I drove from Northfield to Chicago and back to visit my college-age daughter. It was a lovely trip, and the colors were vibrant throughout Minnesota, Wisconsin and in Chicago itself. On the way home, I stopped at the Rotary Botanical Gardens, one of the loveliest small botanical gardens in the Midwest. It’s in Janesville, Wisconsin, about five minutes off of I-90.

While walking through the gardens, which include an elegant Italian formal garden — which really reminded me of the one I’d visited in Rome this spring — a large pond with plantings around it and a number of beds featuring All-America Selections, I was struck by how well the gardeners here combined plants for fall beauty. This combination of several ‘Autumn Brilliance’ seviceberries near the Leonard Messel Magnolia was especially striking. (Unfortunately, my photo does not do it justice.) Interestingly, both of these plants are also vibrant in the spring, with early flowers and have distinct shapes, making them year-round beauties and a dynamite combination.


I’m continually amazed at what plants will do to survive. Recently, while thinning out some overgrown red-twig dogwood, I came across this branch. The canes of red twig dogwood are fairly soft when they form and the bush grows essentially as a thicket, with branches on top of each other and sometimes criss-crossing each other, or as in this case, just making a nice U-turn to go around each other. We should all be so flexible.

A second part of our recent spruce-up was the removal of some old alpine currant shrubs that were dying. The shrubs formed a hedge around an area below our back deck, an area that I use mostly for storage of garden equipment. Not wanting to leave this exposed, I planted it this past weekend with nine plants of hedge cotoneaster (Cotoneaster lucidus), a plant that will grow about 4 feet wide and up to 8 feet tall. We’ll probably keep ours around 5 to 6 feet tall by shaving the tops. The cotoneaster should be an improvement over alpine currant for two reasons. First, it is less prone to disease and general keeling over. Second, has a blue berry that birds love, so it should be more attractive to wildlife. It also has a pretty reddish fall color. Right now, my hedge looks skimpy, but the photo at left is what it should look like in a year or two.

White in the Garden

IMG_6354In clothing and home decor, I avoid white due to my unfortunate tendency to spill coffee. But in the garden, judicious use of white is striking and it often gives a focal point to the garden. Recently, I’ve been enjoying several white patches. In back, these lilies (Lilium ‘Casa Blanca’), which I bought at the MSHS booth at the St. Paul Home and Patio Show this winter,  just started blooming. They are later blooming than other lilies, which may be because the spot in which I’ve planted them is too shady. I will move them this fall into a sunnier spot and remember to stake them next year. These are tall and striking, a real eye-catcher in an otherwise green part of the garden.

IMG_6359Near the lily is this new Annabelle hydrangea bush I planted this spring. Here’s a case of putting the right plant in the right place. Ever since it was planted in this somewhat shady spot, it has looked healthy and happy, and for the past few weeks, it’s been putting out bunches of white blooms. Annabelle is an old-fashioned hydrangea and will get 5 feet tall and wide. It makes a lovely hedge and is a reliable bloomer as far north as USDA Zone 3.

IMG_6365Finally, in the front-door garden, I have white sweet alysum. I’ve had poor luck with alysum in the past, but this year’s relatively cool conditions have been perfect for it. The white color contrasts well with the deep purple of these Wave petunias and the sunny yellow of the coreopsis planted near it.

Some gardeners choose to isolate white in one part of the garden and this can be beautiful, especially at night. If you’d like to try a white garden, check out this article on principles of designing with white.

Hey! It’s Working!

img_1325.jpgI don’t know why, but I am always surprised when some new gardening endeavor actually turns out. About a month ago, I decided to try to force some red-twig dogwood branches. I followed the instructions for making a sugar water/bleach concoction to give the branches food and, presumably, protection from bacteria. The branches went into the cool, not too light basement. A couple of weeks ago, I went down there to add some more liquid and check things out. There were definite signs of leaf buds.

img_1330.jpgToday, I checked them again and, lo and behold, the branches had tiny leaves and some little knobby growths that look like they might be blossoms. Rock-and-Roll Gardener advised me that I would probably only get leaves, but we’ll see what happens. Per the instructions, I have moved the branches up to a sunnier locale in the kitchen. With any luck, we’ll have something blooming in time for our early Easter.

Forcing Red-Twig Dogwood

img_1179.jpgBack in December, I blogged about how wonderful red-twig dogwoods are for providing winter color. In answer to my question about whether to coppice my dogwoods, a reader suggested taking out one-third of the branches each winter and putting the cut branches in water to encourage bloom.

It’s been so cold recently that I haven’t felt like roaming around the yard with a pruner, but Saturday was a pleasant day, so I went out and cut some branches from my rangiest dogwood. I followed the procedure for forcing branches that is outlined at the Purdue University web site. Forcing basically means bringing the branches inside and coaxing them into thinking it’s spring so they will bloom.

Purdue recommends putting the branches in a tall container and using a preservative liquid. The branches are essentially bathed in the liquid, which apparently keeps them healthy and makes them bloom more. I had one nice tall vase to use, but all my other vases have disappeared, so I had to put some of the shorter branches in a martini shaker. (The last time anyone had a martini around here, Reagan was president.) The preservative is a mixture of lemon-lime soda (pop to you Minnesotans), water and a touch of chlorine bleach. The branches will now sit in a slightly dark, cool corner of the basement for a few weeks. If it works, I should have flowers sometime between Easter and April Fool’s Day.
