Campanula portenschlagiana Porto forms a compact, low mat of small green leaves covered by abundant purple cup-shaped bells in summer.
Its spreading shoots soften wall edges, rock gardens, paths, and containers, and the display can continue into early fall where conditions remain favorable.
Grow it in full sun or partial shade in moist but sharply drained soil. Water moderately, avoid soggy roots, and remove spent stems to keep the mat neat.
