Golden St. John’s Wort (Hypericum frondosum - ‘Sunburst’, bred for showy flowers and a more compact form, is pictured here) grows to around 3’ high and wide in sun to part shade. This low maintenance shrub is native to the Southeast and up into Missouri and Kentucky. That range falls into Zones 5-8; it may be evergreen in Atlanta and die back to the roots in St. Louis. Yellow summer flowers fill the plant in summer. Later, the seed capsules are attractive additions to flower arrangements with Dahlias, grasses and Asters.
Shrubby St. John’s Wort (Hypericum prolificum) is a 2-4’ shrub that is native to the Eastern half of the United States. While ‘Sunburst’ is a showy option for landscapes, Shrubby St. John’s Wort seems to be a better native choice to attract pollinators, handle moist soils, and grow into Zones 3-4.
Some species, like Hypericum perforatum, are European/Asian natives and considered invasive here. It is worth it to do a bit of research before buying a St. John’s Wort to make sure you bring a happy, unfussy addition into your garden.
