Propagation & Germination

Pre-treatment: Seeds are soaked in water to remove any inhibitors and allow full imbibition prior to sowing. Seeds are then sown into deep flats and covered with composted leaf mold.

Establishment: Blaw is indigenous from eastern Africa and tropical Asia, northern Australia to the Marshall Islands and southeastern Polynesia, but not to Hawaii. It is a common coastal strand plant. Mature fruits are hard, ovoid, and yellow-green that turn black at maturity. Fruits are collected throughout the year.
