Penstemon 'Osprey' is a vigorous large-leaved bushy perennial with exquisite, tubular-shaped, green flowers and a soft pink mouth, with an extraordinarily long flowering season, from early summer through to late autumn. Growing to a maximum height of up to 100cm, and spreading to around 60cm. It's tolerant of all soil types provided they are moist and well drained, and hardy as long as it isn't cut back when frosts are likely.
