Aitchison's false spirea
FamilyRosaceae
Sorbaria aitchisonii, commonly known as Aitchison's false spiraea, is a vigorous deciduous shrub with an upright, spreading habit, valued for its finely cut foliage and feathery summer blooms. Its compound leaves, resembling those of the Rowan tree, emerge soft green in spring, then turn medium green in summer before taking on golden-yellow hues in autumn. In summer, it produces large, upright panicles composed of small, slightly fragrant, creamy-white flowers, which are highly melliferous and attractive to pollinators. Ideal for naturalized beds, informal hedges, or plantings in cool soil, Sorbaria aitchisonii tolerates humid conditions well and adapts to cold climates. It prefers well-drained to moist soil and a sunny to partially shaded exposure to ensure vigorous growth and abundant flowering.
