Wall Bellflower
Campanula muralis
Campanula portenschlagiana (syn. Campanula muralis) is a vigorous, mat-forming evergreen perennial prized for its profusion of star-shaped, violet-blue flowers and its ability to thrive in rock walls, crevices, and dry, well-drained soils. This tough, low-growing plant forms a dense, spreading carpet of small, rounded to kidney-shaped, glossy, dark green leaves. From late spring through summer, it is covered with an abundance of upward-facing, star-shaped, bright violet-blue flowers (to 1 inch across), creating a spectacular, long-lasting display that attracts bees, butterflies, and other pollinators. Exceptionally adaptable, drought-tolerant once established, and able to cascade beautifully over walls, it is an outstanding choice for rock gardens, stone walls, slopes, borders, containers, and as a colorful ground cover in sunny to partially shaded areas.
