Olearia ilicifolia
Propagation: Seed - surface sow in early spring in a greenhouse. Do not allow the compost to dry out. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first winter. If growth has been sufficiently good, plant them out into their permanent positions in early summer of the following year, otherwise grow them on for another year in pots and plant them out the following early summer.
Cuttings of half-ripe wood, 5 - 10cm with a heel, July/August in a frame. Pot up in late August and overwinter in a cold frame then plant out in late spring or early summer[1]. Good percentage[2].
Cuttings of moderately ripe wood of the current years growth, 5 - 10cm with a heel, November in a frame. High percentage[1].
Cultivation: Succeeds in any well-drained moderately fertile soil in full sun[3][4]. Thrives in a chalky soil[3] but prefers a light loam or peaty soil[2]. Very tolerant of maritime exposure[2][5].
This species is not very hardy outside the milder western and south-western maritime areas of Britain[6], tolerating temperatures down to about -15°c[4].
Closely related to O. macrodonta, but somewhat hardier, it succeeds outdoors at Wakehurst Place in Sussex[2].
The flowers have a strong musky perfume[7]. The plant flowers best in years following long hot summers[4].
Plants can be pruned right back into old wood in order to promote fresh growth[4]. Any pruning is best done in the spring[2].
The flowers are fragrant[8].
Range: New Zealand.
Habitat: Lowland to sub-alpine forest and scrub, southwards from latitude 38°s on North, South and Stewart Islands[9].
Usage: Very resistant to maritime exposure and tolerant of severe pruning, this plant can be used as an effective windbreak hedge in exposed maritime areas. It is best if left untrimmed[10].
Pollinators: Insects
Soil: Can grow in light and medium soils.
Drainage: Prefers well drained soil.
Wind: Tolerates maritime wind exposure
In Leaf: Evergreen
Flower Type: Hermaphrodite
Also Known As: Eurybia dentata linearifolia.
