Let’s Understand Hypericum perforatum?
Perforate St John’s wort is a herbaceous perennial plant with extensive, creeping rhizomes. Its reddish stems are erect and branched in the upper section, and will grow up to at least one 1 m (3 ft 3 in) high. The stems are woody near their base and could appear jointed from leaf scars.

The branches are typically clustered with regards to a depressed base. It has opposite and stalkless leaves that are narrow and oblong in condition and 1-2 cm (0.39-0.79 in) long. Leaves borne on the branches subtend the shortened branchlets. The leaves are yellow-green in color, with scattered translucent dots of glandular tissue. The dots are conspicuous when organized to the light, giving the leaves the “perforated” appearance to that your plant’s Latin name refers. The flowers measure to 2.5 cm (0.98 in) across, have five petals and sepals, and are colored bright yellow with conspicuous black dots. The flowers appear in broad helicoid cymes at the ends of the upper branches, between late spring and early to mid summer. The cymes are leafy and bear many flowers. The pointed sepals have black glandular dots. The countless stamens are united in the bottom into three bundles. The pollen grains are ellipsoidal. The black and lustrous seeds are rough, netted with coarse grooves.
When flower buds (not the flowers themselves) or seed pods are crushed, a reddish/purple liquid is produced.
It really is probable that Hypericum perforatum originated as a hybrid between two closely related species with subsequent doubling of chromosomes. One species is certainly a diploid a subspecies of Hypericum maculatum, either subspecies maculatum or immaculatum. Subspecies maculatum can be compared in distribution and hybridizes easily with Hypericum perforatum, but subspecies immaculatum is more similar morphologically. The other parent is almost certainly Hypericum attenuatum since it possesses the top features of Hypericum perforatum that Hypericum maculatum lacks. Though Hypericum maculatum is mainly western in its distribution across Eurasia and Hypericum attenuatum is mainly eastern, both species share distribution in Siberia, where hybridization likely occurred. However, the subspecies immaculatum now only occurs in south-east Europe.
The standard name “St John’s wort” allow you to make mention of any species of the genus Hypericum. Therefore, Hypericum perforatum can also be called “common St John’s wort” or “perforate St John’s wort” to differentiate it.
St John’s wort is known as as such since it commonly flowers, blossoms and is harvested through the summer solstice in late June, around St John’s Feast Day on 24 June. The herb will be hung on house and stall doors on St John’s Feast day to guard against evil spirits also to guard against harm and sickness to man and live-stock. The genus name Hypericum is possibly produced from the Greek words hyper (above) and eikon (picture), in reference to the tradition of hanging plants over religious icons inside your home during St John’s Day.
