Morphology

Perennial medium-growing (60-80 cm high) plant with erect red tinted sessile shoots, characteristically translucent leaves, bright yellow flowers gathered in dense corymbs.

Aboveground shoots are hairless, cylindrical in cross-section, woody at the base, herbaceous and slightly branched at the top, opposite foliaged.

Leaves sessile with obtuse apex, entire-margined, slightly sinuate, elliptic-lanceolate, as if perforated with veins lighter than the rest of the blade. Light or contrary “holes” in the leaves are in fact hypericin reservoirs.

The flowers clustered in dense corymbs are strongly yellow, stalked, actinomorphic, composed of calyx and corolla, up to 3 cm wide, attractive to insects. The petals of the corolla, just like the leaves, are entire-margined and “holey” (equipped with hypericin reservoirs).

The fruit of Hypericum perforatum is a multi-seed three-lobed capsule, about 1 cm long. The seeds are cylindrical, black or brown, and speckled with lighter spots.

In plantations, seedlings and young specimens are sometimes watered. Older specimens can withstand even severe drought. For better yielding, it can be fertilized in spring and summer..

The harvest of perforate St. John’s wort is carried out at the beginning of flowering, before the herb starts to woody, usually in June, sometimes repeating the harvest in August / September.

Use Value

Perforate St. John’s wort provides bees only with pollen, but it is sometimes sown in southern Europe in flowerbeds, vegetable gardens, herbal plantations, and even bee pastures.

However, the richness of pollen makes it a plant very attractive to wild pollinators.

It is almost melliferousless, although St. John’s wort honey is said to have herb-like properties (diastolic, analgesic).
