About

Geranium (Cinereum Group) 'Lambrook Helen' is a clump- and mat-forming herbaceous perennial with a low, trailing habit and silvery, dissected leaves. It produces flowering stems from June to September that rise just above the foliage. Suited to full sun in a sheltered position, it prefers neutral, moist but well-drained soils. Use it as a carpeting plant in borders, rock gardens, woodland beds or containers.

In the garden

Geranium (Cinereum Group) 'Lambrook Helen' sits in the Geraniaceae as a mat-forming, trailing perennial that holds a low profile through the season. Its foliage is finely dissected and silvery, making the leaf texture and tone the primary feature through much of the year; flowering stems appear from June to September and stand slightly above the leaf mat. Plant it in full sun on a south-, west- or east-facing, sheltered spot where the soil is neutral and stays moist but drains freely. It tolerates sandy, loamy and clay soils provided they are not waterlogged; aim to avoid permanently wet conditions at the crown. The cultivar is rated H7, fully hardy for UK gardens, so it overwinters reliably once established in a protected site. Where space is limited, 'Lambrook Helen' works well at the front of a border, spilling from containers, or as a ground cover between rocks and path edges in cottage or woodland-style beds. Allow the mat of silvery, patterned leaves to spread and link planting pockets together to form a continuous carpet through the growing season.
