Etymology

Hymenosporum is composed of the words “membrane” (from Greek hymen) and “seed” (from Greek sporos). Flavum means “pure yellow” (Latin).

Description and flowering period

This erect tree reaches 10 to 20 meters in height. Its foliage is dense and persistent. It is composed of 10cm long, dark-green shiny lanceolate leaves (spearhead shaped). The star-shaped flowers have 5 petals which are cream-coloured at first but later turn bright yellow. They are very fragrant and attract bees, birds and butterflies. The fruits are long pear-shaped seed capsules which are dehiscent (opening spontaneously when ripe). The seeds are winged and disseminated by the wind.

Habitat

As a rainforest species, it requires a humus-rich, fresh yet draining soil. It can be planted in full sun or part-shade. Avoid cold spots as it is quite sensitive to cold temperatures (especially when young).

Uses

Ornamental.

Notes

Despite its Australian common name, it is not botanically related to frangipanis. It is the only species in the Hymenosporum genus.
