Deciduous & Flowering Shrubs

Prairie Petite lilac

Syringa vulgaris 'Prairie Petite'

Prairie Petite common lilac brings fragrant, light pink spring flowers that fade toward lavender to a compact, deciduous shrub. Expect about 3 to 4 feet in height and spread at maturity; a documented older plant reached just over 3 feet tall and 4 feet wide. Give it a sunny place near a path or in a border where its spring scent and flowers can be enjoyed. Well-drained soil, moderate moisture, and room for air movement suit common lilac; neutral to slightly alkaline soil is preferred. Prune just after bloom to preserve next spring's flowers. It may produce suckers as it ages.

Choose a full-sun site with space for the shrub's roughly 3 to 4 foot mature spread. Avoid crowding it against other plants.

Through the seasons

Fragrant, light pink flower clusters appear in spring and fade toward lavender. Green leaves drop in fall.

A little care goes a long way

Growing well, season after season.

Remove faded flower clusters if desired, and prune soon after flowering so next spring's buds can form. Thin older stems when renewal is needed.
