The Yellow Sea Aster (Asteriscus maritimus)
The Yellow Sea Aster (Asteriscus maritimus, Spanish: Estrella de Mar, Catalan: Pare i fill), also known as Sea Aster, Sea Daisy or Gold Coin, is in flower now, between April and July. It can be found in coastal areas, here in the Western Mediterranean basin as well as in the Canaries. The good-looking flower can be cultivated in your very own rock garden, too, and keeps well in pots.
This species prefers a well-drained, preferably sandy soil with moderate levels of moisture and exposure to full sun. Propagation is by seed or cuttings. You may find it in your local garden centre.
