Sunny Disposition, Shady Needs

It is always a topic of conversation: What plants work well in sun or in shade? Or both? However, the conversation has taken on a slightly different perspective for 2014.

The plant world has been turned upside down due to a disease that has impacted one of gardeners’ favorite shade plants — Impatiens walleriana. Impatiens are the standard for any annual shade garden, and varieties belonging to this class have died in Europe, the U.K. and now, North America, from a disease called downy mildew (Plasmopara obducens). Infected plants start to drop leaves overnight and only the plant stems remain after a few days. So what can you replace them with to give color in a shaded location? Here are a few suggestions.

Beyond Violet

African violets are pushing the envelope when it comes to colors and flower forms. Ruffles, anyone?

When I was a child, I was totally mesmerized by the intense colors of the African violets that seemed to bloom continuously on my grandmother’s windowsills. I would stare in wonder at those jewel-colored blooms surrounded by collars of fuzzy leaves, fully convinced that only experienced gardeners of my grandmother’s reputation could get plants to bloom so gloriously indoors.


A New Twist on Terrariums

They’re back, just in time for holiday decorating and gift giving! Terrariums, that is. They’ve recently made a big comeback with a new twist and a few new favorite plants.

If you were gardening in the 70s, you probably planted up an old aquarium, apothecary jar or any clear glass container with an opening large enough to squeeze through a plant. Many of us used long handled tools to strategically place plants and decorative items in containers too small to accommodate our hands. The containers were then covered with some kind of glass lid to increase the humidity.


Butterflies in February?

On a sunny winter day a few years

ago, I strolled into our Palos-area garden looking for signs of snowdrops. The snow was melting, leaving behind large patches of wet soil around the tree trunks. The air was calm and the day was somewhat downright mild for February — almost 50 degrees. Out of the corner of my eye, something darted just above the ground — a mourning cloak! I had read that mourning cloak and question mark butterflies occasionally ventured out from their winter hideaways — they overwinter here and ca

Illinois is an agricultural state.

We all know that, right?

But did you also know that Illinois imports 90 percent of its food? This is according to an August 24, 2014 article in the Business section of the Chicago Tribune.

So what’s wrong with this picture? The hard truth is that most of Illinois is a monoculture of corn and soybeans, which goes to feed cattle in this country and abroad. We’re not a state of home gardeners feeding our families from our backyards. When I buy frozen edamame (whole soybeans) at my local supermarket, I see “Product of China” stamped on the bag. What’s wrong, indeed.

Inspiration On the Half Shell

Some people are known as “glass half full” folks and some drift towards the “glass half empty” side. Personally, I’m a “Whoops! I’m sorry I just spilled that half glass of red wine all over your white lace tablecloth” kind of guy.

I know that many gardeners look at the coming year with anticipation. By January, the unspeakable, unending string of horticultural tragedies of the previous season have been relegated to the compost pile of history, figuratively and literally. (Or is that just my experience?) They view the world – which is pretty much limited to their patios, backyards and all-season deck chairs – with fresh eyes, convinced that this is the year that the porcelain berry vine that strangled their prize affenpinscher will be vanquished, that the heptacodium tree, which died under mysterious circumstances five years ago and which now resembles a hat rack for squirrels, will finally be removed (if only by a wind storm), and that the drainage issues that had them considering creating a rice paddy by the recycling bin will miraculously be alleviated by a climate-change-induced drought that begins in April and lasts through, oh, 2023.


Mike’s “Bargain Basement”  Holiday Hort Sing Along

People ask me why, year after inexplicable year, I continue to crank out these bizarre little lyrics for the holidays. Normally, I nod and smile and ignore the question. But when it’s your shrink who is pleading for an answer, uh … let’s just say that I said I would think it over, but, gee, I’m on deadline and I’ll talk to you next week.

I’m not sure that counts as an answer. I’ll let you know next year.

It’s a bird, it’s a plane … it’s a flash mob of garden writers!

Late last summer 420 garden writers from the U.S. and Canada assembled for their annual symposium and ended up dancing to Pharrell Williams’s “Happy” on the lawn in front of the University of Pittsburgh’s “cathedral of learning” (watch the video here: bit.ly/1ttDyjf).

While it may not rank up there with the moon landing, it’s sure to find a beloved spot in the annals of the Garden Writers Association (GWA), founded in 1948 with a current membership of 1500.


Go Pantless … er, Plantless!

If there’s absolutely one thing I’m sure of as I slog through this vale of tears, it’s that the MacArthur genius grant people have, tragically, lost my phone number. Why, I can think of at least half a dozen reasons why I should be cashing one of their big, oversized checks and then retiring to an exotic location like Minot, ND. (Slogan: “Why Not Minot?”)

The surprise is that there have been so few surprises. But maybe that’s just what happens when you plant a 5-acre “stylized prairie” in downtown Chicago and half of the species selected are Midwestern natives. Even when the world-renowned plantsman making the choices was from Holland and had never seen a real honest-to-gosh prairie until he came to America several years ago.

The man in question, Piet Oudolf, was in town this summer for the 10th anniversary of the establishment of The Lurie Garden in downtown Chicago’s Millennium Park, and Chicagoland Gardening was able to steal a few moments from his busy schedule to sit down and get his perspective on what he had done.

questions

What is rose rosette disease? I lost two antique roses and removed a hedge of multiflora roses that were supposed to be undesirable. How bad is it?

Can you tell me if the African daisy Osteospermum ‘Springstar Aurora’ can be winterized here? It is a healthy plant?

I want to raise the level of my lawn as much as 2 feet in places. I now have a large quantity of somewhat composted wood chips and I am wondering if I can use them as fill to raise the ground level and provide a good soil in which to sow a lawn.
