Shrubby St Johnswort, Hypericum frondosum, is a native shrub found most often in rocky glades. This one is not to be confused with the European St Johnsworts commonly seen in landscaping. Shrubby St Johnswort blooms in June and July and produces so much pollen that honeybees turn bright yellow working its blooms. Its bright yellow flowers stand out against the sea of mid summer green. The tan seed capsules add interest long after the sunny flowers are gone
It is hardy in zones 5 to 8 and grows to 3′ to 4′ tall. When grown in the open, it becomes a mounding shrub. This is a good choice for dry rocky locations with difficult soils.
