Pulmonaria ‘Spot On’, known in the garden as Lungwort ‘Spot On’, combines blue-toned blossoms with a volume that is easy to place in a composition. The foliage features shades of green and silver, which can be highlighted among different textures. The usual blooming period is in May. At maturity, expect 40 cm in height and 50 cm in width, which makes it suitable for use in partial shade beds and woodland gardens.
Soil choice is essential for Lungwort ‘Spot On’: it should be kept moist and clayey. The preferred exposure is partial shade to shade. For Lungwort ‘Spot On’, regularly check the soil around the root ball: it should remain moist. Water at the base when the surface begins to dry and adjust waterings according to rainfall; this exposure (partial shade to shade) does not eliminate water requirements. A margin corresponding to its 50 cm spread avoids having to move the clump in the first few seasons. The indicated hardiness zone is zone 3, to be assessed according to your garden conditions.
When planting Lungwort ‘Spot On’, after the flowers, remove damaged leaves if necessary and support regrowth with appropriate watering. Lungwort maintains cleaner foliage in light shade where the soil does not dry out completely. For companion planting, consider astilbes, tiarellas, and hostas in varieties with similar needs. Keep its 40 cm height in mind to place lower plants on the correct side and allow the flowers to be visible during May.
