Description
Amelanchier canadensis Glenform Rainbow Pillar is a very floriferous columnar ornamental shrub which offers a dazzling spectacle throughout the seasons. In spring, it is covered with white star-shaped flowers, followed by dark red edible fruits that turn black when ripe. Its dark green foliage turns orange-red to purple in fall, before falling and revealing its silvery-gray branches. This serviceberry tree is distinguished by its slender, columnar shape, which allows it to adapt to small spaces. It reaches approximately 4 meters in height and 1.5 meters in width.
To grow Canadian serviceberry Rainbow Pillar in the garden, you must choose a sunny or partial shade location. It appreciates fresh, humus, but well-drained soil, but tolerates poor or sandy soils. It should preferably be planted in autumn or early spring, by digging a hole twice as wide as the rootball and adding compost or decomposed manure. It is necessary to water regularly the first year, then in case of drought the following years. It is also necessary to mulch the base to keep the soil fresh and prevent weeds.
Amelanchier canadensis Glenform Rainbow Pillar can be integrated into the garden in different ways. It can be planted alone, in a free hedge or in a clump, associated with other spring-flowering shrubs. It can also be grown in a container on a terrace or balcony, provided you repot it every two years. To balance its silhouette, it can be cut back by a third after flowering and pruned lightly at the end of winter to remove dead or damaged branches. It is also necessary to provide it with organic fertilizer in spring to encourage its growth and flowering. Finally, it is necessary to monitor the possible appearance of diseases or parasites, such as powdery mildew, rust or aphids, and treat them with suitable products.
