Description
Hypericum prolificum
Also known as:shrubby St. Johnswort
,Hypericum spathulatum
Description
Hypericum prolificum is a low-growing, compact deciduous shrub with neat, rounded habit. It typically grows no taller than 4', and the same across, with dense, light green foliage. The showy, bright yellow flowers are produced either singly or in terminal clusters, and are about 1" across. The specific epithet - prolificum - refers to the conspicuous stamens that are so numerous as to overshadow the petals.
Cultivation
Shrubby St. Johnswort is very easy to grow, adaptable, and trouble free. It is not particular about soil and will tolerate poor, thin, sandy or rocky ones, and even heavy clay. Established plants will withstand short periods of inundation as well as extended dry spells. Flower production is best in full sun, but it performs also quite well in part-shade. The blooming period is extensive, lasting up to 2 months during the summer. Any pruning should be done in early spring. Zones 4-8
Propagation
Can be propagate from seed, without special treatment, although the process is slow. Easiest to propagate from softwood cuttings.
Additional Notes
This species is attractive when grown as a specimen, as well as planted in large groups. It can be used as a low-growing hedge or foundation planting, and is also an excellent choice for erosion control. It is resistant to deer and other herbivores.
