Hidcote St. Johnswort is a stoloniferous shrub that grows to a height of 18 to 24 inches and spreads as wide or wider. Flowers almost 1 inch in diameter have bright yellow petals with reddish anthers. Peak bloom occurs in June and early July; however, flowers continue to appear into fall. This woody ground cover is evergreen farther south and semi-evergreen in mild Illinois winters. Renewal- prune in the late winter for vigorous new stems. Sunny yellow flowers and rich green foliage much of the summer create continuing appeal. This first-rate hybrid is best used as a ground cover or in a hedge and is deer resistant.
