Hypericum prolificum - SHRUBBY ST. JOHNS WORT

This shrub flowers for two months and is "always buzzing,“ as it is very attractive for bumblebees and other pollinators. Nice native plant with showy yellow flowers (¾–1" across). Tolerant to black walnut! It naturally forms rounded mounds, but can be sheared in early spring for a better shape.

Adaptable to soil and moisture. Can be planted in any landscaping project, pollinator garden, butterfly garden, cottage garden, low maintenance planting, rain garden or along roadsides. Looks good with lower-growing and mound-forming perennials or groundcovers, or with smaller shrubs. Try it in combination with the contrasting blue flowers of Geranium x ‘ Rozanne,' Nepeta x faasenii ‘Six Hills Giant‘ (or other variety), or blue varieties of Salvia nemorosa and Veronica! Other good matches are Aster dumosus, other hardy Geranium, Heuchera, Sedum telephium, Waldsteinia, and many other perennials.
