Square Stemmed Marsh St. John's Wort Hypericum tetrapterum - 1L Pot
Hypericum Elodes is a delightful rafting aquatic plant used for flowering pond margins and creating a good habitat for pond creatures. It is very similar to the Hypericium Elodes but has a more square stem. It has attractive green leaves, which are hairy and rounded, growing on its sturdy stalks which lead up to delicate yellow flowers. Each petal of the flower has beautifully subtle lines which cause a fine contrast. Hypericum Elodes is an evergreen plant, which means that the foliage of the plant persists and remains green throughout the year.

Caring and Maintenance:
This is a very low maintenance plant which requires a well moisturised environment. Propagate by division at the end of summer or very early in spring. Cuttings may be taken in the summer.
Help to conserve our native British flora by planting with our native plant range. These marginal pond plants grow naturally in the shallow water at the edge of the pond and are ideal for wildlife ponds or water features. As well as their attractive foliage and flowers, they provide a natural habitat for small pond creatures. The rafting varieties, such as the Water Forget-me-not, Brooklime, and Water Mint, spread out in small floating rafts, giving cover to baby fish and tadpoles. The tall emergent plants are essential for dragonflies and damsalfly nymphs to climb out of the water and transform into adults, and waterfowl like to nest among dense reeds and rushes. All plants contribute to the ecological haven of a natural pond, benefiting wildlife from tiny pond insects to mammals that like to visit for a drink.
