Propagation

Seed - untreated seed has a germination rate of 5 - 30%. Pre-soaking for 3 days in cool water, or scarifying the seed can increase this rate to 65%, whilst reducing germination time to 2 - 8 weeks. Seeds should be planted in a shallow container in a well-draining medium. The planting medium should be keep moist until germination and the containers should be kept in a covered shaded area for better control of moisture levels[

The fruit of Colubrina oppositifolia is a almost round capsule 1/2 inch in diameter. The capsule has 3 parts and there are generally several seeds in each capsule. The dark brown to black oval seeds can be up to 1/4 inch long. The fruits ripen from late spring through early fall. The capsule opens explosively when it is mature. Full-sized fruits that have not completely dried and are still greenish-brown often contain more viable seeds than completely mature capsules. These not-quite-mature fruits should be ripened in a dry location free from insects for a few weeks. The seeds can be extracted after this process[
