Menyanthes trifoliata,Bogbean is a PERENNIAL growing to 0.3 m (1ft) by 1 m (3ft 3in).

Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid and neutral soils. It cannot grow in the shade. It prefers wet soil and can grow in water.
Cultivation of Bogbean:
Grow in a bog garden in wet peaty soil or in shallow water at the edge of a pond. Prefers acid conditions. Succeeds in water up to 30cm deep. Dislikes shade. Plants can be very invasive, spreading by means of long-creeping thick surface rhizomes . A very hardy plant, tolerating temperatures down to about -25°c. Cats are very fond of this plant.
Propagation of Bogbean:
Do not allow the seed to dry out. Sow late winter to early spring in a pot in a cold frame and keep the pot just submerged in water. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in trays of water in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring. Very easy, the divisions can be planted straight out into their permanent positions if required. However, particularly with smaller divisions, we find it better to pot them up and grow them on in a cold frame for a few weeks until they are established. Cuttings taken in summer can be inserted into the mud at the side of the pond and will normally root well.
