These are the daisy bushes, so called because of their numerous, daisy-like. All are evergreen and all will grow in most adequately drained soils, including chalk and limestone. They will withstand salt-laden wind, which makes them good shrubs for seaside gardens, and Olearia haastii is also an excellent town shrub. But not all are fully hardy so selection must be determined by the kind of temperatures likely to be experienced in winter.
O. haastii, 5 to 6 ft. high, with small, roundedand a dense habit which makes it suitable for use as a screen or hedge, is probably the hardiest, but its white flowers in July—August are not so pure a white as those of O. scilloniensis, 3 to 4 ft. high, with small grey and flowering in May—June. O. gunniana and O. stellulata are similar to the last named, but the latter also has blue and pink-flowered forms, distinguished as variety splendens. O. macrodonta has the largest leaves, resembling those of a holly. It has big flattish clusters of scented white flowers in June, can reach 10 ft. and is a very handsome shrub often used as a windbreak in maritime gardens.
Most kinds prefer warm sunny places, but O. haastii will grow in semi-shade. All can be cut back in spring, if necessary, but with some loss of flower that summer. They can also be trimmed after flowering.
