The Terrace and Sunken Garden.
A small spreading daisy like plant native of Mexico, that has established itself in many Mediterranean areas and dry gardens in Britain. It looks most effective creeping down the sides of stone or brick steps or tucked in wall crevices, where it both seeds itself and also spreads slowly with its rhizomatous roots.
Site and Care:
Good drainage and plenty of sunshine are essential for plants to survive cold damp winters. Plants are easily raised from seed, in the spring, which may be scattered in the cracks between paving stones or sown in a pot or tray and allowed to self-seed.
