Waifs and strays

img_2939Most experienced gardeners know it’s best to invest in a well-grown, top-quality plant. Well tended plants have the vigour and stamina needed to make the successful transition from nursery pot to garden. Once in awhile, though, I’m drawn to a less-than-stellar specimen at an end-of-season sale. Something about it telegraphs, “please give me a chance,” and I do.

Take the tree peony shown here, which was little more than a stick when I scooped it up a couple of years ago for $4. The few leaves it had were healthy and green, so I gave it a little talking to, a bit of TLC and planted it in the ground. This year, it’s powered up into a big, beautiful plant and rewarded me with more than a dozen massive, brilliantly hued blooms.

img_2963Ditto this Japanese maple, which I rescued quite late one fall for $20. A few of its branches had been broken off and it was a bit lopsided, but basically it appeared to be healthy and just needed some gentle pruning. I placed it in the back of the garden where its spindly condition wouldn’t be so noticeable.

Plain old Acer palmatum is the most commonly sold and hardiest of the Japanese maples in our Zone 6 Toronto climate, and I figured it had more of a fighting chance of surviving that first winter than some of the fancier, more finicky, cut-leafed marquee types. I was right. This once-scraggy example is now well on its way to becoming a graceful, shapely small tree.

Of course, I would never buy a plant that is clearly diseased or really needs to go to that great garden in the sky, and neither should you. But it’s fun to adopt a promising mutt and see it grow into a champion.

Another thing I love about gardens is the way mystery plants crop up in unexpected places. These may be gifts from the squirrels or the wind.

img_2931img_2967A lone candelabra or Japanese primula (Primula japonica, far left) appeared in the garden this year. I didn’t plant it, but it seems to have made itself right at home. And columbine (Aquilegia spp., left) in various colours seeds itself hither and yon, including in between the patio pavers.

A couple of doors up, the neighbours have a fine show of Allium giganteum, below. I grow various types of alliums as well, but not this one. However, I now have several of these in my front garden, courtesy of the squirrels (and inadvertently, my neighbour. Luckily I live on a very friendly street).

img_29461Take a look around your garden and see what unexpected gifts you might find out there. And keep your eyes open at the nursery for those orphan plants that deserve a good home and a fighting chance.

The plot thickens

img_2889Of all the seasons, my grandmother loved spring the best. I’ve always been an autumn girl myself, but as I grow older I’m growing more partial toward spring as well. It’s a celebration of renewal; nature’s annual affirmation of faith in the future of this planet.

As you can see by this photo of a corner of my back garden taken this morning, everything is growing by leaps and bounds. Later in the season my patch will mostly be in shade, but I’ve learned to embrace this.

So what should you be planting right now? I’ve carefully put in a few more ferns and hostas, but cautious Clara here is keeping a watchful eye on other emerging perennials before I plant more stuff, because it’s oh-so-so easy to be over-hasty and dig up or damage plants that are simply slow to get started.

And personally, I never buy tender annuals until after Victoria Day, which is early this year. This week,  Toronto has had some nippy nights with frost warnings, so I’ll likely wait awhile before I go shopping for my favourite tuberous begonias, which are such beautiful plants for shade. Use your judgment and don’t buy too early if it’s cold where you live.

But there’s absolutely no need to feel gardening-deprived. Because across much of the country this is the ideal time to put in perennials, shrubs, trees and evergreens; in fact, you really want to shop for those as early as possible for the best selection. One caveat—to optimize sales, perennials in nurseries and garden centres are often forced into full bloom out of their normal cycle. Keep this in mind when shopping. Once established, unless it’s an early spring perennial such as brunnera, it’s unlikely your plant will bloom at this time in your garden. Nor will all your plants bloom at once! It’s best to do a bit of research before you buy so you can plan for a sequence of bloom throughout the season. And once you’re at the nursery, choose perennials that are bushy and compact with strong stems and loads of growing points and buds, as opposed to tall and lanky and in full bloom.

It goes without saying that spring is a very busy time for garden centres. Once there, even super-organized gardeners with itemized lists are likely to be seduced by something fabulous and unexpected, but that’s part of the fun.

Aimg_28661s a master gardener, part of my commitment involves putting in a minimum of 30 volunteer hours a year. And there’s nothing nicer than doing that while being surrounded by top-quality plants. So in the past several weeks I’ve had the pleasure of advising gardeners at Islington Nurseries in the city’s west end, and helping at the Toronto Botanical Garden’s plant sale, which was held last week. Paul Zammit, the new director of horticulture at the TBG, brought in some dandy plants. Some of the choicest specimens were scooped up by the mad keen plant nerds on Day One, but there was plenty from which to choose on Day Two as well, which is when I put in my shift. One of the biggest bargains there was this magnificent serviceberry clump, which I scooped up for my daughter’s garden. The price? Just $19.99. I should have bought more.

Good Ideas for Small Spaces

Every spring, Loblaw companies generously invites garden journalists from Toronto and southern Ontario to a luncheon and preview of their new President’s Choice plants, garden equipment, accessories and decor (to check where they’re available in your area, go to presidentschoice.ca). There are always some good ideas to take away, not to mention armloads of fabulous plants they give us plant piggies to trial at home.

This year, a couple of things struck me as being great for gardeners with limited space, such as a tiny urban lot or a balcony.

One of these is a President’s Choice clematis that offers two types in one pot. Developed by Britain’s famous Raymond Evison, it’s guaranteed for one year and sells for $24.99; mine combines wine-red Rebecca with periwinkle-blue Cezanne, both hardy to Zone 4. Double the colour punch, but takes up the same space as an ordinary clematis.

Another smart idea is a handsome, square planter of herbs. The one I picked up is ready-planted with sage, rosemary, thyme, parsley and chives—just the thing to pop on the back deck near my kitchen. (Or on your apartment balcony?)

img_2892However, my favourite item, shown here at the side of my house, is this compact, rectangular rain barrel. I bought it yesterday for $74.99 on sale at my local Loblaw store, and will hook it up to my downspout this week. I don’t have enough space for one of those huge round standard-sized rain barrels, but this is just the job, and will help keep rain away from the foundation of my house. The brown colour blends in with the brick of my house, but you could always paint it something else with one of the new paints that adhere to plastic, such as Krylon Fusion.

And of course, there’s nothing better than soft rain water for your plants.
