Sea thrift in Spain: drainage matters more than feeding

Thrift, or sea pink, is a low evergreen cushion plant with grass-like leaves and papery globes of pink or white flowers on wiry stems in late spring. The familiar species is Armeria maritima, which grows on exposed coasts and other open ground across the temperate northern hemisphere. It can suit a coastal Costa Blanca garden because it tolerates salt wind, poor soil and drought once established.

A genus with Spanish roots

Thrift is not only an import. Flora iberica records an unusually rich and taxonomically complex Armeria flora across the Iberian Peninsula, including narrow endemics. For a garden, buy a correctly named, nursery-propagated plant suited to the site. Never collect an endemic from the wild or assume that any Spanish Armeria will tolerate a hot coastal garden.

Where to grow it

Thrift wants full sun and the sharpest drainage you can give it: a gravel garden, a raised bed, a dry-stone wall, a trough or the front edge of a sunny border. It tolerates salt spray and reflected heat. What it will not tolerate is rich soil, shade, crowding by larger plants or wet roots, any of which can cause the centre of the cushion to rot and die out.

Care

Water new plants until they are established, then only in extended drought. Do not feed. Remove faded flower stems after blooming to keep the plant neat. Cushions can become woody and bare-centred after a few years; lift and divide them in spring, replanting the vigorous outer sections, or start again from seed.

In the garden

Thrift works as edging, in a trough and on hot banks where little else will hold. It combines well with other tough sun-lovers such as Sedum, Dianthus, sea lavender and dwarf grasses. The flowers draw pollinating insects.
