Other Uses

Hedge;  Hedge.

Very resistant to maritime exposure and tolerant of severe pruning[11, 49, 166, 200], this plant can be used as an effective windbreak hedge in exposed maritime areas[75]. It is rather slow growing though[75].

Cultivation details

Succeeds in any well-drained moderately fertile soil in full sun[182, 200]. Thrives in a chalky soil[182] but prefers a light loam or peaty soil[11]. Very tolerant of maritime exposure[11, 75]. Tolerates atmospheric pollution[200]. This species is not very hardy outside the milder western and south-western maritime areas of Britain[1], tolerating temperatures down to about -10°c[184]. Another report says that it is hardy to about -15°c[200]. Very slow growing in Britain[75], the plants generally only reach 2 - 3 metres tall in cultivation in this country. Plants can be pruned right back into old wood in order to promote fresh growth[200]. Any pruning is best done in the spring[11]. Some named forms have been developed for their ornamental value[182]. Flowers best in years following long hot summers[200]. The flowers are sweetly scented[184].

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[78]. Good percentage[11]. Cuttings of moderately ripe wood of the current years growth, 5 - 10cm with a heel, November in a frame. High percentage[78].

Olearia albida tests positve for saponins in the leaves and the wood(A New Zealand Phytochemical survey Part 2 By R.Campbell, Cain & Roche NZ Journal of Science Sept 1961).

I shook some leaves in a jar of water, after 12 hrs the amount of bubbles wasn't bad, have not tried using them for anything, washing, killing fish...

The plant tested negative for alkaloids and all other things tested.

I am impressed with my one plant, it is growing pointing into the prevailing while other plants grow sculpted with the ocassionally hurricane force wind as one would expect, (observation based on one plant only) it is rather slow as you say though, and doesnt get very big at it's best.

We were given a small plant of this as a housewarming present 18 years ago for the garden of our new house in the Orkney Islands off the north coast of Scotland. It has grown to approximately 8 feet tall and ten feet wide and is still going strong. Over the years we have taken loads of cuttings and some (five or six) have survived. We are in the process of severely pruning it as it was beginning to block our view out over the sea so will be planting hundreds of cuttings in the hope that many will survive. This is the first time we have taken cuttings in spring so its fingers crossed and if anyone out there can guide us on the best methods of maximising survival rates we would be pleased to hear. All in all a wonderful plant which reminds us of a wonderful holiday we spent in New Zealand a few years ago.
