Outstanding Qualities

Phlomis tuberosa is an easy-to-grow perennial with an attractive combination of bold, rough-textured, green leaves and soft pink flowers. The flowers, which appear in early summer, are hooded and borne in tiers on tall, slender stems. Bees and butterflies are attracted to their sweet nectar. The flowers develop into ornamental seed heads that persist into winter and provide food for the birds. This versatile plant can be used in the dry sunny border or as an informal groundcover. Phlomis tuberosa combines well with ornamental grasses, lavenders, blue-flowered hardy geraniums, and other drought-tolerant perennials. The leaves are evergreen and the stout flower stems persist into winter, adding interest to the dormant garden.

Culture Notes
This unusual perennial will grow well in full sun to light or open shade. It prefers well-drained or sandy soil and will tolerate hot locations. After flowering in early summer the entire plant will go dormant until the following year. Leave the seed heads until they are no longer attractive. Once established, phlomis is drought tolerant.
