P. russeliana - P. russeliana is a perennial that forms large heart-shaped green leaves on long petioles and whorls of hooded, pale yellow flowers on tall, erect stems from late spring though to early autumn. Unlike many phlomis, it will tolerate some shade.
Water regularly the first growing season to establish the plant. Thereafter, weekly or bi-weekly deep watering is all this plant needs.
Deadheading is will not bring the plants back into flower, but keeps the attractive foliage looking tidy. Cut tall flowering stems where they emerge from the mound of low foliage.
