Campanula 'Acaulis'
- Delivering a spectacular summer show, Campanula 'Acaulis' produces striking, upward-facing clusters of vivid violet-blue bells. This stunning clustered bellflower creates a dense canopy of rich colour from early to mid-summer.
- Living up to its 'stemless' name, it boasts a superbly compact, low-growing habit that reaches just 15cm tall. This diminutive stature makes it an absolutely perfect choice for rockeries, alpine troughs, or edging the very front of a sunny border.
- Despite its small size, it is a vigorous, rhizomatous perennial that forms a fantastic weed-suppressing mat. The lush, heart-shaped green leaves provide excellent groundcover and remain attractive throughout the entire growing season.
- It is a fully hardy, low-maintenance plant that is highly resistant to deer and rabbits. Thriving in full sun or partial shade, it simply requires moist but well-drained soil to reliably return and spread year after year.
- Blooming profusely during the warmest months, it serves as a fantastic magnet for pollinating insects like bees and butterflies. Adding this charming little plant to your garden brings a lovely buzz of beneficial wildlife right to your planting scheme.
