Because the temperature in my greenhouse can reach 140oF on a sunny summer day, most of my greenhouse plants spend the summer on my patio. Come fall, however, these plants must be moved back into the greenhouse. For them, it’s rather like returning to an indoor home after enjoying summer at the cooler, breezier beach. […]

Stained glass windows have been around a good deal longer than Glasshouses, yet it would seem that the two have something to offer each other. Wafting around the National Botanic Garden of Ireland  in September I was fulfilling a bucket list item; I’d long known about but never visited the graceful Curvilinear Range and its […]

Recently, while walking through the aisles of the Independent Garden Center trade show in Chicago, I discovered a product I’d never seen before—containerized hedges. A row of neatly sheared plants outlined the booth. Clearly, they were field-grown and root pruned, their branches naturally intermingling. It was a living privacy wall you could buy. It would […]

A Michigan cottage I often visited as a child had an old deer head over the door known as George. He’d been there for decades and his antlers were used as a hat rack. But he had an ancient, moth-eaten dignity about him, and I always think of George when I see a grand staghorn […]

Growing flowers in winter gives cheer to cold, gray, snow-covered days and can make you feel that spring is truly just around the corner. An array of beautiful flowering plants can be “forced” into blooming no matter how frigid and dreary the outside world is. And if you own a greenhouse, you can create a […]

Phillip Johnson’s “Glasshouse” in New Haven, Connecticut, is one of the icons of mid-century modern architecture. Steel-framed and glass-walled (hence its popular name) it seamlessly blends indoors and outdoors. It’s sophisticated simplicity has been the pattern for much early-21st century design. The photograph below, from my book, The Midcentury Modern Landscape,  shows a Johnson-inspired modernist […]

What would September be without dahlias? Oh, there would still be flowers in the garden—anemones, turtlehead, asters, goldenrod, even some hostas—but none of them packs a punch of color like dahlias. Red, purple, white, pink, yellow, orange, every color but blue can be found in dahlias. They stand on stiff, hollow stems that can be […]

It’s that time of year when horticultural trade shows deliver the best and brightest for next year’s market. I was lucky enough to attend several, including the Independent Garden Center Show in Chicago and the FarWest Show in Portland, Oregon. That’s where I met up with Nancy Buley, Communications Director of the wholesale company, J. […]

Pots are essential in a greenhouse, but picking which pot to use for which plant isn’t always easy. The options come in many different shapes and sizes as well as different materials and colors. So how do you select the best pot for a particular purpose? A few tips will help. Choosing a pot of […]

This month I’m looking at what can happen when private gardeners take their passion public. Streissguth Gardens is a private/public enterprise that could be duplicated in neighborhoods all over the country. Recently, I went for an urban hike with friends on the east side of Seattle’s Lake Union. On Blaine Street, we arrived at a […]

Mulch: the magic M-word that every gardener should know and practice, in the garden and even in the conservatory. Why mulch? Some may think that mulch is just cosmetic, improving the looks of a garden. That it does, but it’s main attraction is far more complex­­—and interactive set of attributes that keep the garden looking […]

Gardeners have a different perspective on the weather than most people. We are cheered by July downpours and winter storms that spread insulating snow. We love cool, wet springs that lengthen bloom time, while other people are anxiously waiting for the year’s first shorts-and-T-shirt day. Stretches of hot summer days may delight children and beachgoers, […]
