Serbian Bellflower
Serbian bellflower (Campanula poscharskyana) is a trailing, fast-covering bellflower for walls, slopes, and the front of beds. Plants form low mounds and send out prostrate stems that root as they go. Starry lilac‑blue flowers appear in late spring and can continue in cool summers. It thrives with regular moisture and part shade in hot regions. Very warm nights can reduce vigor and flower set. Fragrance is minimal.
