This genus belongs to the Mint family and includes about 100 perennials as well as subshrubs from the Mediterranean and western Asia. Drought resistant and hardy, many of the species will thrive in warm sunny sites and dry woodland edges. Ornamental whorls of purple, pink or yellow blooms open in the summer, providing long-lasting stems and flower clusters for fresh and dried decoration in the garden or kitchen.
Brightened by white heavily veined undersides and light fuzzy stems, thick heart-shaped pewter green leaves craft a handsome flanneled appearance. Stiff swarthy stalks thrust upward, interspersed with large long lasting showy whorls of spicy scented helmet-like, rich yellow flowers. This rugged shrubby perennial develops a somewhat woody foundation over time, and always brings fulgent accents to hot exposed slopes, wind-swept seaside plantings or any other sharp-draining sunny locale.

Launched in 1967 by Hilliers, a celebrated British nursery that supposedly received the namesake’s own garden seed, this grand hard-to-find Phlomis is an evergreen hybrid between Phlomis fruticosa and Phlomis russeliana.

Daring spade-shaped green leaves, flashing felted finishes and silver undersides, attire staunch square upright stems beneath a colorful bumble-bee haven.
