A compact, deciduous shrub that typically grows to 4” tall in warm
winter climates, but grows closer to 1.5-2” tall in colder climates
where it usually is cut or naturally dies to the ground in winter. Features
rose-like, 5-petaled, waxy, cupped, golden yellow flowers (3’ diameter)
with numerous, prominent, dark yellow center stamens. Flowers of this
popular hybrid are unusually large, slightly fragrant and bloom throughout
the summer. Dark green, lance-shaped leaves are 2-3’ long. Reddish,
twiggy stems. RHS Award of Garden Merit. Plants of the genus Hypericum
(some species have been used since ancient times in the treatment of wounds
and inflammations) were apparently gathered and burned to ward off evil
spirits on the eve of St. John”s Day, thus giving rise to the genus
common name of St. John”s wort.
Root rot and wilt can be significant problems in hot and humid climates.
