My brother and I have harvested a ton of seed from our genetically different Strelitzia nicolai Another link
These plants become giant! They are very commonly planted around my area, and have quite beautiful flowers. The seeds...they are some of the most ornate I have EVER seen! They are black with a flaming orange tuft.
Anyways, the seed is from two genetically different plants. The tallest of which is IDK how tall, but to the roof of a two story building, so probably close to the maximum height of 20 feet. Seriously, they almost beat our queen palms!
The plants are quite drought tolerant once established. They make a great privacy screen, and add height to your yard.
Seed is here for trade. A bubble envelope will be needed as the seed is the size of green peas.
PM me or post what you have here!
