Rainbow Pillar Serviceberry

Rainbow Pillar Serviceberry (Amelanchier canadensis 'Rainbow Pillar')

Rainbow Pillar Serviceberry (Amelanchier canadensis 'Rainbow Pillar') is a narrow, upright selection of the native shadbush, valued for its tight columnar form and vibrant seasonal transitions. Selected for its vertical habit and striking fall color, 'Rainbow Pillar' delivers white spring flowers, edible summer berries, and foliage that lights up in brilliant tones of orange, red, and yellow. This cultivar is especially well suited for urban gardens, hedgerows, and compact planting sites where space is limited but seasonal interest is essential.

Distinctive Features

'Rainbow Pillar' grows 15 to 20 feet tall and only 4 to 6 feet wide, forming a dense, columnar silhouette that stays tidy with minimal pruning. Clusters of fragrant white flowers bloom in early spring before the foliage emerges, followed by small purple-black berries that are edible and loved by birds. As autumn approaches, the green leaves turn vivid shades of scarlet, orange, and gold�giving the cultivar its name and creating a brilliant vertical focal point in the landscape.
