Saxifrage

Cushion forming, low-growing, evergreen perennial alpine plant that produces attractive purple flowers in spring. These are held very close to the rosettes of foliage. It dislikes wet conditions so a gritty free-draining compost is essential. It can be grown outside in very dry spots but is often best grown in pots of free-draining compost. It's an excellent choice for a rock garden or stone trough. Surround plants with a thick layer of grit to prevent waterlogging around the crown of the plant and deter slugs from damaging the plant.
