General Culture:

Best grown in organically rich, medium to wet, well-drained soils in part shade. Soils must be kept uniformly moist and not allowed to dry out. Best performance occurs in cool summer climates where night temperatures consistently dip below 70F degrees, which unfortunately is a cultural preference that does not fit the profile of a typical St. Louis summer where this plant often labors. In optimum growing conditions, plants may spread by stolons and self-seeding. This plant does not reliably come true from seed, however.

Noteworthy Characteristics:

‘Sunningdale Variegated’ is a great masterwort cultivar that is noted for its attractive variegated foliage. This is an umbelliferous, stoloniferous, clump-forming perennial that typically grows to 24” (less frequently to 30”) tall. Each flower is a domed umbel of pinkish-white florets subtended by a showy ruff of papery, petal-like, green, pink and white involucral bracts. Flowers bloom from late spring to early summer. Bracts usually remain attractive well after bloom. Medium green leaves are splotched with cream and pale yellow. Each leaf is palmately cut into 3-7 (usually 5) toothed lobes. Leaves appear primarily in basal clumps, with smaller versions on the stems. Variegated leaf colors tend to fade as summer progresses.
