Penthouse Gardening with Mandevilla and Skyline

Every spring, I plant flowerpots for a client living on the border of Westmount, Quebec. There is great spiritual excitement working at this site. We garden on the top floor of a twelve-story assisted-living apartment building for seniors that sits at the highest point of Mont Royal, Montreal’s mountain in the middle of a city, modestly landscaped by Fredrick Law Olmstead twenty years after he created New York City’s Central Park.

To the south, we see the Saint Lawrence River and the Champlain Bridge that crosses it; to the west, a  horizon boasting the outline of a new hospital complex, beyond which the skyline fades into the river and the rural areas beyond. To the east, we admire the western slope of the mountain dotted with the lush green clouds of densely populating treetops that grace the elegant homes surrounding this residential municipality.

At this height, we feel a soothing silence broken first by the roar of wind blowing across the Saint Lawrence Valley as it bounces off the southern face of the mountain and second by the music of wind chimes that float from a neighboring penthouse on the same floor. Fortunately, the flowers that I plant are protected from the ethereal gusts of wind by clear Lucite panels that shelter both the client and her potted garden.

The spring sun bathes us in warmth as we work under bright skies that glow in a shade of blue rarely seen at street level; the birds in the treetops provide songs-to-plant-by and on dull days, the unobstructed view of dramatic cloud formations fill us with awe as they float before our eyes.

My staff and I feel a little closer to heaven gardening at this height with such a panoramic view. Although we spend hours designing and planting flowerpots, what we do here does not feel like work. This annual project is an opportunity to experience spirituality. Regardless of their age, personality, gender or field of study, none of the college students who help me plant remain unmoved by what they see.


Success with Flower Pots and Containers Requires Trial and Error

http://foreverflowercontainers.comWhen I began to design flower gardens, many clients asked me to fill their containers as well. That’s when I dived, head first, into a craft for which I was as yet unsuited and unprepared. Guided by the beautiful photographs in the trade publications, I copied the compositions in the pictures and sourced the same types of flowers that had been used. Unfortunately, the results were never spectacular.

It was only by reading several books on container gardening that I came to understand my own shortcoming and the limited power of the plants that I has selected. The first thing that I learned was that flower pots need potting mixture to grow successfully. I had been potting flowers with rich black garden soil. Containers, I now understand, need feeding every two weeks. I did not know that, but I do now. Containers also need frequent watering. I had been neglectful of that and now I know better.

My lack of experience was also responsible for me making the strategic error of believing that annual flowers in pots bloom all summer long. Who knew that plants could be spent by July and need replacing? I know that now. However, the biggest lesson learned from my trials and errors is not to trust the advertisements for annuals or to rely upon the professional flower arrangements that are photographed for magazines. Those pots look good when planted but not a few months later.

The greatest deception of all is the industry’s encouragement to use specific annuals because many of them are flowers that simply can’t deliver. Like most gardeners, I was so impressed with the hype and appearance of Calibrachoa and Bacopa that when they failed to perform, I was greatly disappointed. These plants are not nearly as attractive in a real container as they appeared in print. The colors are harsh, and do not project. Furthermore, they do not become more attractive after planting. They seem to be at their peak when purchased and then deteriorate until the end of the season.

Summers are short in USDA zone 4 and sometimes spring never comes. With such a protracted season for enjoying flowers, we require reliability. Here it is not OK for flower pots to appear spent by mid summer. By that time, the local merchants of annual flowers have dismantled their kiosks so that replacements are impossible to find. Another lesson learned, now that we are experiencing summers with unending rain, is that dahlias will rot if planted in pots if there is no opportunity for the soil to dry out.

When all of my attempts to creatively plant containers failed, it took a while for me to realize that so many of the most spectacular potted floral arrangements still depend upon pelargonium and begonias as main plants. In the end, what once appeared to me to be old fashioned and overused has turned out to be the most reliable.


Creative Design for Container Gardening; a book review.

Gardening With Color Rob Sproule,  Lone Pine Publishing,

We were introduced to Rob Sproule last year when he published a delightful manual titled New Annuals for Canada. In it, the author wrote about the effective use of annual flowers for colder climates, where short growing seasons are prevalent. In this, his second endeavor, he focuses on the use of annuals for designing and planting containers under the same climate conditions.

The newer book contains 60 design ideas for container gardens. Here are solutions for those that lack the confidence to design their own or for those who feel that their innate creativity still remains untapped. Each of the suggestions is accompanied by a planting diagram, a list of suitable flowers and foliage, and care instructions. The reader is encouraged to consider them as inspiration, to be adapted to ones personal taste and needs. The plans also include guidelines for the size of a container, the recommended amount of sun, water and nutrition, the projected aggressiveness of the component plants and a caution about the restrictions of climate. In addition, the author surveys materials required as well as soil and potting mixes.

Mr.Sproule deals with pertinent topics such as foliage, hanging baskets, the classical style of planting flower pots, and the creative use of color. In the final two chapters, the reader is introduced to modern and contemporary influences in container design and is given suggestion on how to create imaginatively by thinking outside the box.

In a short, magnificent, gem of a chapter dedicated to the elements and principles of design, the author has concisely summarized everything we need to know about this subject. Many books have been published about design in general, and garden design in particular, but none have been able to summarize the science of design as clearly as Mr. Sproule has done. Read the book for this chapter alone; the balance is a useful and informative bonus.
