Q. Please tell me about Shasta daisy and its care.
The crowns of Shasta daisy (Leucanthemum x superbum, formerly called Chrysanthemum maximum) can get quite congested, so division to regenerate the clumps is recommended every 2-3 years. A few cultivars have been bred for seed use by the larger wholesale growers, but most do not produce seed. The taller vegetative varieties, produced by cuttings or divisions, usually have larger or more distinctive flowers.
It is important to distinguish the Shasta daisy from the common field daisy, or ox-eye daisy, L. vulgare, which is listed on some state noxious weed lists; the ox-eye daisy can colonize fields quite quickly and has shown up in our gardens as well as at plant sales. If you do grow this one, it is best to deadhead so seed is not produced; it has very nice flowers, with a size proportional to stem length, and usually does not need staking.
Origin: Europe, temperate Asia. It prefers moderately fertile, rich, and well-drained soil with average moisture. Provide sun to part shade. Shade the double blooms from intense sun.
Propagation: Division for all L. x superbum cultivars in spring or late summer; seed for L. vulgare and L.v. 'Maikönigin' ('May Queen').
