What is the Puakenikeni Flower?

The pua keni keni, sometimes called perfume flower tree, grows as either a big bush or a little tree that spreads out. People in the Samoan Islands call it pua-lulu, while in Tonga and Tahiti, they just say pua.

Pua kenikeni is native to Northern Australia and the Caroline Islands extending to the Marquesas, and thrives on high islands across this region. It populates various habitats, from lowland to montane forests, often gracing lowland lava flows in Samoa, narrow ridges in Rarotonga, and montane and cloud forests.

In some regions, cultivation prevails, notably in Tonga, potentially its native habitat, and Hawai’i, where it has been recently introduced.  The tree, typically a shrub but capable of attaining a height of 15 m (50 ft), is valued for its aromatic white flowers, serving as a garden ornament and a source of timber.

  • They are typically reaching up to 15 meters in height, though often shorter, especially in open environments and as a strangler. The trunk tends to be many-branched at the base, featuring a spreading crown.
  • The flowers form a terminal, many-flowered cyme, usually with 9-25 flowers, branched at the base.
  • The calyx is urn-shaped, 9-16 mm long, with 5 ovate sepals.
  • The trumpet-shaped corolla is white, aging to yellow or pale orange, with a tube measuring 4-11 cm long.
  • The stem is divided into 5 oblong, contorted lobes, each 1.7-3.6 cm long. Flowering can occur throughout the year, sometimes continuously.
  • Leaves are simple, opposite, and fleshy, mostly elliptic to obovate, ranging from 8-22 cm in length.

Growth and development of Puakenikeni Flower

  • From the very beginning, this plant starts slow, often taking a few years to reach a height of 1 m (3.3 ft).
  • On the other side, plants grown from air layers or cuttings show quicker growth.
  • The speed of growth is interesting; a rooted cutting of 0.5 m (1.5 ft) may hit 2 m (6.6 ft) in 3-5 years under good conditions, displaying its life vividly.
  • Flowering and fruiting happen throughout the year, with occasional highs. Samoa, for example, experiences a peak in flowering from May to September.
  • Plants propagated vegetatively usually start flowering a few months after being planted.
  • Yields are promising, as the tree, though at times irregular, generously produces many flowers.
  • The plant easily reproduces through seeds, but seedlings may take 5-7 years to bloom.
  • Air-layering, a common technique, yields flowering plants within 9 months under perfect conditions.
  • Air-layering, preferably on 1-2 years old branches, involves girdling and removing a bark ring 2-4 cm (0.8-1.6 in) wide. Hormone treatment with IBA (indole butyric acid) helps in root formation.
  • A moist rooting medium like sphagnum moss is packed and wrapped with impermeable material.
  • After 6-8 weeks, check for roots, and upon sufficient growth, carefully separate and transplant into a pot.
  • The planting varies but is typically 45 cm (18 in) tall and 1-2 cm (0.4-0.8 in) in diameter at the base.
  • Successful air-layering, followed by container growth, ensures a 100% survival rate. Pua kenikeni can flourish in a minimum 5-gallon container.
