Pieris japonica 'Interstella'

Interstella Pieris

Pieris japonica 'Interstella' is an evergreen shrub that produces a profusion of ruby-red, bell-shaped flowers. Originating from East Asia, this cultivar begins its blooming season in late winter to early spring, with the floral display often lasting up to two months. The abundant, lantern-like blossoms dangle gracefully from fine stems, creating a beautiful contrast against the plant's lush, dark green foliage.

Following the flowering period, 'Interstella' showcases dramatic red new growth, adding another layer of visual interest. This dynamic transition from blossoms to colorful foliage makes it a standout choice for gardeners seeking year-round appeal.

Design tip

Extend the seasonal display by treating ‘Interstella’ as a succession of two strong color moments rather than a single flowering shrub. Ruby-red flowers dominate in late winter and early spring, followed by dramatic red new foliage that carries the color forward after blooming ends.
