Pre-treatment: Remove outer husk from mature seeds and soak in water for 24 hours to soften outer seed coat, then rub off by hand.

Establishment: The Pritchardia affinis, also known as the Hawaiian fan palm or loulu, is endemic to South Kona, Hawaii. It flowers and fruits year-round, but pests such as rats eat the mature seeds. Cross pollination with other primarily exotic Pritchardia species is common, so hand pollination is required to obtain true seed. After hand pollination, bagging the flower stalk in tough screen followed by a paper bag helps to deter predators and reduces the chance of cross pollination with other species of Pritchardia. Seeds are mature when they turn from green to brown.
