Bellflower, Serbian 'Blue Waterfall'

Bellflowers are among the most popular of perennials. This dwarf selection may be grown in rock gardens, used as an edging, or in tubs and pots. Plants form a spreading patch of small green leaves, which expands to a much larger floral display, bearing loads of starry violet-blue flowers beginning in late spring and blooming for weeks on end. Nice when used as a groundcover over a smaller area, especially under shrub roses, or perhaps cascading over rocks or a wall. Will sometimes repeat flower in the autumn.
