My garden is bordered by dry stone walls (most likely the local limestone). How do I establish alpines in the crevices to make a display in the walls themselves?

Hope someone can help?

Hi, Margaret,
The crevices in the wall must be large enough to hold the root ball of the plant and deep enough for the roots to take hold. And though alpines typically need good drainage, there needs to be a some type of shelf or barrier at the bottom of the crevice to prevent the soil and plant from eroding. Once planted, they will need to be watered frequently to help them establish. Though not an alpine, have you considered Erigeron karvinskianus or Erigeron 'Profusion' - lovely daisy-like flowers and these plant thrive in crevices. They are drought tolerant when established, too. Wisley has used them in crevices in the stones in the steps and surrounding paving at the formal pond near the entrance to the gardens - gorgeous!
