Cultivation Details
Prefers a good sandy loam rich in humus[1]. Succeeds in full sun or light shade[2]. A very wind hardy plant, tolerating maritime exposure[3, 4]. A very ornamental plant[1], it is not very cold-hardy, tolerating short-lived lows down to about -10°c[5]. It only succeeds outdoors in the milder areas of Britain[1, 6, 7]. It grows very well in Cornwall where it often self-sows[1, 6, 7]. A form with purplish leaves is hardier than the type and succeeds outdoors in Gloucestershire[6]. The flowers have a delicious sweet scent that pervades the air to a considerable distance[8]. The tree has a strong tap root[9]. Mice often kill young plants by eating out the pith of the stem[6].
Propagation
Seed - pre-soak for about 10 minutes in warm water and sow in late winter to early spring in a warm greenhouse[10, 11]. The seed usually germinates in 1 - 3 months at 25°c[11]. There is usually a good percentage germination[10]. Prick out the seedlings into individual pots as soon as they are large enough to handle and grow them on in the greenhouse for at least their first winter. Plant out in late spring after the last expected frosts and give the plants some protection in their first winter outdoors[PFAF]. Stem cuttings - cut off the main stem just below the head and then saw off 5cm thick blocks of stem and place them 3cm deep in pure peat in a heated frame. Keep them moist until they are rooting well, then pot them up into individual pots. Plant out in late spring after the last expected frosts. Suckers. These are best removed in early spring and planted out in situ. Protect the division from wind and cold weather and do not allow the soil to become dry until the plant is established. Divisions can also be potted up and grown on until established, planting them out in the summer.
