Hypericum frondosum

Also known as:

cedarglade St. Johnswort


golden St. John's-wort


blueleaf St. John's wort

Scientific Synonyms:

Hypericum aureum, Hypericum splendens


Hypericum frondosum is a very attractive, compact, low growing shrub That can be considered semi-deciduous or even evergreen in the southern parts of its native range. The 3" oblong leaves are blue-green and showy. Summer brings an abundance of mostly solitary, five-petaled yellow flowers with dense pompom-forming stamens. These give way to showy, 1/2 inch long, reddish fruit capsules that will persist on the plant well into winter. The bark is also reddish and exfoliating, giving the shrub additional winter interest.


Cedarglade St. Johnswort is easy to grow and low maintenance. It does well in average, well-drained soils. It is susceptible to root rot in poorly drained soil. Full sun is best, but it will tolerate some shade particularly in the hotter southern limits of its range. While semi-evergreen in the south, shrubs may suffer winter top-kill in the northernmost parts of their range. Dead or damaged stems can be safely removed, even cut back to the ground without affecting summer blooms which only occur on new growth. Its dense, well-rounded form makes it a good choice as a solitary specimen or foundation plant. It can also be used effectively as a hedging shrub, or planted in masses.


Propagate from semi-hardwood cuttings. Can be propagated from seed without pretreatment, but development is slow.

Additional Notes

Hypericum frondosum is a highly ornamental shrub with year round interest, that has mostly been underutilized and commercially overlooked.
