Dahlia merckii

A graceful, clump-forming tuberous perennial with finely divided, mid-green foliage that gives the plant a light, airy appearance. From mid to late summer and often continuing into autumn, delicate single soft lilac-pink flowers with golden-yellow centres are borne on slender stems.

Grow in fertile, humus-rich, well-drained soil in full sun. It will reach a height of 2m and a spread of 1m.
