Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Kalmia polifolia Common Name: Swamp laurel Family: Ericaceae Author: Wangenh. Known Hazards: The foliage is poisonous to animals[21, 65, 76]. The whole plant is highly toxic[222]. Mature Height: 0.5 Mature Width: 0.5 Habitat: Cold peat bogs and other wet places[11, 200].
Propagation Notes: Seed - surface sow in late winter in a cool greenhouse in light shade[78, 113]. Prick out the young seedlings into individual pots as soon as they are large enough to handle. The seedlings are rather sensitive to damping off, so water them with care, keep them well-ventilated and perhaps apply a fungicide such as garlic as a preventative. Grow the young plants on in light shade and overwinter them in the greenhouse for their first winter[78]. Plant them out into their permanent positions in early summer. The seed is dust-like and remains viable for many years[113].
Cuttings of half-ripe wood, August in a frame. Very poor results unless the cuttings are taken from very young plants[11, 78].
Layering in August/September. Takes 18 months[78]. The plants can also be dug up and replanted about 30cm deeper in the soil to cover up some of the branches. The plant can then be dug up about 12 months later when the branches will have formed roots and can be separated to make new plants[200].
