Phlomis grandiflora NJM 10.014

A potentially large species, rarely seen in cultivation but as hardy as P. fruticosa. This is common in SW Turkey where I found it making huge mounds of pale grey foliage up to 1.8m high by 3m across, but usually smaller. Masses of bright yellow flowers in early summer on long stalks held high above the foliage. For a sunny well drained position.
