Pulmonaria x 'Trevi Fountain' (Lungwort)Stunning deep cobalt blue flower clusters are carried above the heavily silver spotted dark green foliage in April and May. The parentage of P. longifolia makes this lungwort a good choice for hot humid southern climates. Foliage fills out quickly in the partly shaded garden and grows to 12" tall. Plants must be provided well drained soil or will rot, especially in wet winter soils. PP#13047 Sunlight Requirements: Partial Shade to Full Shade USDA
