A tree or shrub native to New Zealand. In the UK grows to 3m or higher as a naturalised escapee near the coast where it is warmer.

Leaves resemble those of Holly, hence the name.

The white Daisy-type flowers grow clustered together in a neat hemisphere up to 10cm across. Round whitish flower clusters have a passing resemblance to those ofSweet Alison, a much shorter plant also found near the sea but which belongs to the Cabbage Family (Brassicaceae).

Each flower has about 20 or so white ray-florets, and a creamy-yellow central portion containing the disc-florets.

Individual flowers fairly small, just 6-8mm across.

There are five similar bushes that grow in the UK, but this is the most frequently encountered and the only one with toothed leaves.

Leaves ovate, dark-green, alternate and with cusped teeth similar to those of Holly. Glossy above, but downy-whitish below.

With pink pappus later in the season it is still impressive even when in seed.

Each flower gives rise to a small multitude of seeds with pappus.

Most seeds still attached here. The pappus is simple, rather than on the end of a single hair..

Many pappii have become entangled in others on their attempted escape, such as the upside-down one at the top. The seed is long, square in cross-section with slight ridges on the corners. The ridges adorned with very short appressed hairs directed towards the pappus, enabling it to be spread either by the wind (with the aid of the pappus) or by attachment to fur (by means of the short hairs). The seeds later turn brown when ripe.


Not to be semantically confused with : New Zealand Flax, New Zealand Willowherb, New Zealand Bittercress or New Zealand Pigmyweed [plants with a similar name but belonging to differing families].

Related to similar shrubs :

  • Mangrove-leaved Daisy-bush (Olearia avicenniifolia) with flat leaves and rounded clusters of white flowers.
  • Akiraho (Olearia paniculata) with wavy-leaves and pyramidal clusters of white flowers with very few central disc-florets.
  • Coastal Shrub Daisy (Olearia solandri)
  • Ake-ake (Olearia traversii) with flat leaves and pyramidal clusters of greyish flowers.
  • Daisy Bush (Olearia × haastii) the hybrid between Mangrove-leaved Daisy-bush and Olearia moschata. It has yellow flowers and flat leaves.
which all grow naturalised in the UK, none of which have toothed leaves.

Uniquely identifiable characteristics

Distinguishing Feature :

No relation to : Holly [a short tree with similar name and similar leaves belonging to a differing family].

New Zealand Holly is the most frequent of the six Olearia genus evergreen shrubs that are naturalised in the UK, and is the only one with toothed leaves. It has a strong musky odour. It is widely grown near the sea where it is warmer, where sometimes it naturalises.

Another shrub also belonging to the Dandelion & Daisy Family (Asteraceae) is Shrub Ragwort, the well-known garden plant 'Senecio Sunshine'; which was called (Senecia greyii) but now known as Brachyglottis × jubar. This has yellow flowers which last but a couple of weeks and the flowers do not cluster so closely together nor are they in hemispheres.
