Spotted St. Johnswort (Hypericum punctatum)

Hypericum punctatum is known by the common name Spotted St. Johnswort. This is one of several Hypericum species that grows in this area. I’ve seen it along the trail in open woodlands south of the Fishing Area (segment 13). It began blooming in mid June.

The plant in bloom.

Plants grow about 24-30 inches high in this area.

Blooms beginning to open. The spots on buds, flowers, and leaves are quite obvious.

The spots are very obvious on the back side of this bloom.

The leaves are simple and opposite.

Spots are also visible on the stem and leaves.
