White Persicaria and Red Roses

White Persicaria polymorpha, Rose Emily Carr and on the left foliage from Eupatorium purpureum that will bloom later in the seasonThe above drama occurred serendipitously.  Originally, a flowerbed was planted to be a theatre perormance. Contrasts in colors, textures, heights, and movements supplied by a composition of continuously blooming roses and perennials were created for the pleasure of apartment dwellers when they looked down from their terraces high above a garden in a private park.

The tall red roses planted five years ago – Emily Carr, from the Canadian Artists collection of hardy shrub roses - were the focal point of the flowerbed. Although they looked stunning in bloom, something was amiss because most of the strong visual energy that the roses supplied weakened by the time it reached the twelfth floor above. More staging was required.

The solution and inspiration came from a visit to a wholesale perennial grower in the countryside. A large round flowerbed was planted in the center of a circular driveway to serve as a landmark for clients approaching along a winding country road.

In the centre of the 10-foot diameter bed, three Persicaria polymorpha perennials were planted in triangle formation several feet apart from one another. At the time of my visit, the composition had matured over three years to create a tall swaying grove of white feathery texture.

The very rugged but elegant plant, also known as Knotweed, is a sun perennial that also grows with magnificence in part shade. The bloom period is quite extensive and the luxuriously sensual flower heads - alive or dead - remain shapely and texturally interesting throughout the season.

To draw focus to the flowerbed, I decided to use this perennial as a proscenium for the red roses. In addition to contributing height and drama, it also diverted tenants' eyes away from a view of the neighboring apartment building.  

However, never was any thought given to the powerful visual impact this perennial might make on the appearance of the roses themselves. Emily Carr roses were intended to be the main attraction, to enhance the appearance of other plants and to give pleasure to the apartment dwellers. Instead, Persicaria made the roses appear to bloom more beautiful than ever before. It enhanced the red color; it showcased the shape of the flower; it made the composition glow and gave it movement. A new dimension to the overall design of the garden was created simply by planting this white perennial behind the red roses. That is serendipity.

Allan, Are the Emily Carr roses fragrant? I'm looking for cold-hardy roses that also have good fragrance, and I've noticed that fragrance is often traded away for hardiness. Besides, I'm a fan of Emily Carr and would be honored to have a rose named for her in my garden.

Jean,
Rose Emily Carr has no noticeable fragrance. I had to adjust to the reality that hardiness and continuous bloom are more important for my very specific garden design needs than fragrance. I miss the pungent intoxicating aroma of hybrid tea roses but I don't miss the intermittent blooming or the feeding, watering, pest spraying, and winter insulating they require.

lovely combination, I had been looking at aruncus in many forms and am astounded at how similar that feathery white bloom is to it, off to try to find some now at our nurseries :)

Gardening is the best thing one can do. Some people don't go on vacations because they have to water the plant. Such is the connection between the people and plants. Thanks for the article.
