Rhopalostylis sapida

Common names

Nikau Palm, Feather Duster Palm.

Curiosities

Sapida means tasty, and refers to the palm heart, apical bud and flowers. Maori people ate the apical bud and the young flowers, and used the leaves to make baskets as well as other tools. They also used the leaves for roof thatching, and in that way their huts were waterproof. This is the southernmost naturally occurring palm in the world, since it grows in Pitt Island, one of the Chatman Islands, at 44º 18’ S, while Chamaerops humilis is the northermost growing palm.

Origin

New Zealand, in Chatman Islands.

Habitat

Rainforest and shady areas, along water streams, although some plants can be found in dryer places.

Morphology

A single trunk up to 10 m, with a prominent crownshaft. Pinnate leaves, with sharp-pointed segments, prominent veins, and a rachis up to 5 m. Inflorescence growing below the crownshaft, around 60 cm. Fruits ovoid and elliptic, strong, and red. The deep green crownshaft makes this palm wonderful and particular.

Climate

Subtropical to warm temperate. Cold tolerant. Appropriate in areas of Mediterranean climate. This palm has tolerated temperatures down to –4.4ºC (24ºF, USDA Zone 9a).

Germination

Seed germination is easy and fast. Seeds germinate in 2-3 months, but seedlings are slow growing.

Growing

Ideal in shade and partial shade, but once the plants have established (preserve young plants from full sun) can adapt to sun. Prefers a rich soil and plenty of water. Since this palm has a deep root system, you will need pots deeper than those used in citrus fruits and roses. Slow growing during the first 10 years, growth speeding up thereafter. Often used in cultivation because of its beauty. Has a very good response to fertilizers. Frost tolerant to -8°C.
