Pachystegia insignis, New Zealand shrub daisy

conspicuous Pachystegia or conspicuous Oelaria, the New Zealand daisy is a subshrub belonging to the family of Asteraceae. This superb species is endemic from Malborough area, whose distribution is limited to the northeast of the South Island of New Zealand, and therefore very localized. It grows on coastal cliffs, sometimes clinging to the wall, but also in riprap further inland.

conspicuous Pachystegia is not threatened; cultivated, it becomes a remarkable and original ornamental perennial, too rarely offered in nurseries: a shrub low also attractive for its foliage persistent than for its inflorescences.

Description of the New Zealand daisy

conspicuous Pachystegia is a small tall and wide shrub from 0.80 cm to 1 m, or even 1.20 m. He has a silhouette relatively prostrate, wider than high, when it is very sunny, but more rounded otherwise. Its branched branches bear beautiful and large whole leaves, alternate leathery, oval, 16 cm long and 7/8 cm wide. They are covered with a very dense tomentum on the young leaves, then only at their margin afterwards, which gives an impression of a silvery outline bordering each leaf dark green.

This leathery foliage , well spread and hemmed in white looks remarkably drawn and gives all its character to the New Zealand daisy.

The inflorescences develop and bloom between May and July: the plant bristles with stems, each carrying a single flower head well released above the foliage, all covered with white velvet. The plant covered with buttons (round and white) is extremely graphic.

conspicuous Pachystegia flowers in a large, flat and regular flower head, a beautiful regular daisy with dense white ligules and a yellow heart, 3.5 to 7 cm wide.

Attracting pollinating insects , the inflorescences turn into small silky red balls: the seeds.

conspicuous Pachystegia ‘Daizea’is the cultivated form of the New Zealand daisy. Suberb, it shows a silvery tomentum more intense than the norm, therefore more contrasting leaves and even more striking flower buds. In addition, its daisies are wider (7 cm).

How to grow the New Zealand daisy?

conspicuous Pachystegia is a resistant plant as long as it benefits from a draining soil. She asks for a sandy or stony land, of a pH between 6.5 and 7.7 . It tolerates the rains as long as the water flows freely from the ground. It is particularly adapted to the Atlantic coastal climate, a little less to the Mediterranean coast, because it can suffer from thirst there in summer. She fears neither the spray nor the wind. She also appreciates a well ventilated situationwhich quickly dries its down after the rain.

conspicuous Pachystegia is cultivated in full sun or partial shade , but you should know that the more the plant will be sunny, the more the contrast between the color of the leaf blade and the white tomentum will be impressive. Likewise, the more light it has, the lower or more compact it remains. It needs direct sun for it to show this silhouette so well drawn.

Hardiness: conspicuous Pachystegia Frost resistant the better the soil is dry (down to -12 ° C). However in our rainy winters, its limit of hardiness is rather of the order of -9 ° C.

The New Zealand daisy will please on an embankmentor in a rock garden . In massif, plan to improve the drainage with coarse sand. It fears limestone and wet soils.

conspicuous Pachystegia can also be grown in containers, in drained soil, but do not forget to water it in summer, and to shelter it from rain and extreme cold in winter (frame, cold greenhouses)

The New Zealand daisy is drought resistant once well rooted in depth. It is preferably planted in spring, and without dismantling the motte of roots. Moreover, not liking that we touch its roots, this beautiful plant lively Transplants better and becomes much more resistant to dryness when implanted from young individuals, so that its roots go deep without ever being disturbed. If you want to change its place, opt for a seedling, a cutting, or to buy a new young plant, because the transplantation of a large plant is illusory.

Care and size:hardly any maintenance is necessary on the New Zealand daisy, except to remove the deflowered heads, if you are bothered by the russet seeds. Reserve 1 or 2, however, if you are tempted by sowing.

If the New Zealand daisy gets too bulky for your liking, it tolerates pruning in spring or late bloom.

Pachystegia significant multiplier comment?

New Zealand shrub daisy maybe cuttings, but the success of this cuttings is not guaranteed. Take a branch with a fairly short heel and push it into sandy or gravelly soil. The heart of the problem is humidity: it must be sufficient so that the cutting does not dry out (possibly smothered cutting), without causing rotting on the felted surfaces of the plant. Root can be favored by bottom heat.

Sowing, on the other hand, is easier, if we allow a few seed heads to mature. These seeds are sown immediately as soon as they come off easily (extra fresh seeds). They are placed on the surface on draining soil, slightly moistened and covered until germination. As soon as the seedlings are germinated, it is necessary to uncover and provide them with good aeration.
