Grassy Bells Seeds

This is a great choice for tough places like atop a wall, a crevice, or any other tight spot. The tidy tufts of lustrous grassy foliage offer a refined cushion from which prostrate stems bear upward-facing, violet-blue bells gathered in abundant, ball-like clusters. It grows 4 to 6 inches tall and spreads 12 to 18 inches wide. It is hardy to zone 4.
Drought-tolerant; it is also suitable for xeriscaping. Kin to the Campanulas and found on limestone slopes from the Mediterranean to eastern Europe, this superb perennial demands well drained, even gritty, soil.
