Pulmonaria longifolia
Also called Joseph And Mary, Long Leaved Lungwort, Narrow Leaf Lungwort
Pulmonaria longifolia, the narrow-leaved lungwort, is a semi-evergreen clump-forming herbaceous perennial plant, native to western Europe, including Britain, France, Spain, Portugal. It grows in semi-shaded habitats, such as woodland and scrub, to 2000 m above sea level.
The stems are upright, 20–40 cm (rarely to 60 cm), not scaly at base, covered with bristly and some glandular hairs. The basal leaves are up to 40–60 centimetres (16–24 in) long and 6 centimetres (2.4 in) wide, narrowly lanceolate, gradually narrowed into a stalk, upper surface usually spotted white or pale green. The stem leaves are lanceolate or oval-lanceolate, stalkless, half-clasping the stem.
In the garden, P. longifolia is hardy to hardiness zone 5. It prefers light shade but tolerates sun better than most pulmonarias, and will not do well in heavy shade. Can be grown on very heavy clay soil.
The following cultivars are available:
Blue Cowslip · Pulmonaria mollis · Unspotted Lungwort · Common lungwort · Red Lungwort · Bethlehem lungwort · Lungwort
