Limonium minutum

A miniature form of Limonium, only 20cm high, a wiry yet appealing little toughie for a trough or rock garden. If you look very closely you see the distinctive flowers of the genus, as seen form the wikipedia photograph of another species. Even in winter the wiry structure has good form. Purplish hues. Extremely hardy. 

Hard to collect the seed and tap rooted. Special for a trough.
