Quick Facts Penstemon pinifolius, Conservation status ...

Growing to 20 cm (7.9 in) tall and broad, it is a small evergreen shrub with arching stems of narrow needle-like leaves and bright scarlet tubular flowers in summer. Its natural habitats in the rocky uplands of Arizona and New Mexico[2] are a clue to its preferences in cultivation. Though moderately hardy to −10 °C (14 °F) it requires an extremely well-drained, sunny position with some protection from hard frosts in winter.[3]

The species[3] and the cultivar 'Wisley Flame' [4] have both gained the Royal Horticultural Society's Award of Garden Merit. 'Mersea Yellow' is another notable cultivar, with brilliant lemon-yellow flowers.[2]
