Hypericum anagalloides

Tinker's penny (Hypericum anagalloides) is a low-growing, mat-forming perennial that prefers consistently moist to wet soil in partial shade, making it an excellent choice for bog gardens or streamside plantings. It requires very little maintenance once established and spreads gently to fill gaps in damp areas. Plant it where foot traffic is minimal and top-dress with compost annually for best performance.
