Characteristics:

Cutleaf fleabane is an attractive wildflower suitable for the rock garden. It is a low growing wildflower with flower stems 5-25 cm high, arising from a basal mat of numerous branched, leafy stems. The herbage ranges from a dense covering of short hairs to glandular. Each leaf ranges from 2-7 cm long and is once to four times ternate. The divisions are are thinly to broadly linear. The leaves of the upper stems are linear or ternate.

The flower heads are solitary atop the flower stems. The disc flowers are yellow, frequently with or without ray flowers in the same population. The ray flowers are white, lavendar, or pink and range from 5-12 mm long. Cutleaf Fleabane flowers from May to August.

Cutleaf fleabane makes an attractive rock garden plant. Make sure that it is not crowded by taller plants, and give it good drainage.
