Plant description
Valued for its slender upright form and dazzling autumn show, 'Rainbow Pillar' is a compact, ornamental tree prized for its white, star-shaped spring flowers that are highly attractive to pollinators. The oblong green leaves turn hues of orange, red, and yellow from late September alongside clusters of blue-black summer berries that offer food for birds. Hardy and adaptable, this Amelanchier develops its end of season hues better in full sun and withstands exposure but prefers a neutral to acid soil. Its neat, narrow habit makes it ideal for small gardens needing a vertical showpiece with multi-season interest.
