In the wild it grows in sandy, stony places among rocks, and the RHS advises protecting it from excessive winter wet. It will rot in wet or waterlogged ground, so do not plant it at the pond margin or in a bog garden.

Packs of 3 come in 7 cm, 9 cm, 1 litre and 3 litre bare-root sizes and cost less per plant.
