The same beautiful silvery whiteness as C. maritima. Fully more compact in growth, the leaves being in shape intermediate between C. maritima and Centaurea Ragusina. Grown with a stem a foot high, this is a very handsome plant, beautiful either for panel-plants or for dotting. To some extent this should supersede the Centaurea, being much more easily wintered, and quite as if not a more handsome plant. It is an excellent dinner-table plant. In hardiness it is the same as C. maritima, but we have not found it so easily propagated. It can be raised easily from seed, but, like its companion, we suppose it will scarcely attain its full coat of sil-veriness the first year. We have not yet had experience of it from seed.
