HAR­DI­NESS: Zones 3–9

CON­DI­TIONS: St. John’s worts thrive in a wide range of soil con­di­tions from dry rocky places to damper wood­lands, as well as av­er­age, well-drained gar­den soils. They do well in full sun, but many thrive in light or part shade too; they do not like deep shade. Sev­eral species tol­er­ate drought and can be used to con­trol soil ero­sion.

BEST FEA­TURE: Most species are grown for their showy, at­trac­tive, usu­ally bright yel­low flow­ers, of­ten cen­tered with a prom­i­nent boss of yel­low sta­mens. A few species dis­play col­or­ful fruits that linger well into fall and are pop­u­lar for flo­ral ar­range­ments. Deer re­sis­tant.
