Care of the plant Hypericum x inodorum or St John's Wort

The genus Hypericum, family Hypericaceae, includes 400 species of herbaceous plants, shrubs and trees distributed by almost all the continents. Some species are: Hypericum x inodorum, Hypericum calycinum, Hypericum olympicum, Hypericum polyphyllum, Hypericum elatum, Hypericum canariense, Hypericum fragile, Hypericum balearicum, Hypericum androsaemum.

Common names: St John's Wort, Tutsan. It's a hybrid between Hypericum androsaemum and Hypericum hircinum.

They are semi-perennial subshrubs that reach 1.20 meters in height. The leaves are opposite, oval, large and deep green (pink when sprouting). They produce small and numerous yellow flowers with long stamens. They bloom in summer. The showy fleshy fruits can be red, pink, white or orange.

They are used in rockery, as isolated specimens, in borders, in light undergrowths and as cut flowers for floral decorations and bouquets.

Hypericum x inodorum needs a sunny or semi-shade exposure. They resist the heat of the Mediterranean summer and frost down to -15 ºC.

The soil can be a mixture of 50% garden substrate, 25% coarse sand, and 25% compost. Planting is done in autumn.

Water regularly (without ever flooding) waiting until the substrate is almost dry.

Fertilize with compost in the fall.

Prune intensively (up to 2/3 of its height) in late winter.

They are sensitive to the attack of fungi such as Rust.

They propagate from seeds sown in the fall or spring.
