This is a gorgeous Sea Holly that forms a basal (ground-level) rosette of deep green leaves with very striking white veins. This beauty produces greyish-white flowers on 40cm stems in Summer. Cut back immediately after flowering to put energy back into the crown. Full sun, well-drained soil that is not too rich. Tolerates drought. 40cm (when in flower) x 30cm approximately.
