How to breed white lilies

Crinum forms bulbs (tubes) at the base of the flower head.

These are not seeds, but plant them to grow new plants.

If left to fend for themselves, the bulb will become very heavy, causing the stem to fall to the ground.

Within a few weeks, the bulbs take root and grow.

New plants may start with variegated leaves and then become pure green when they mature.

To propagate or share plants, wait until the process goes smoothly, and then dig and divide new plants.

This is much easier than trying to divide mature plants.

The Crinum bulb grows very large.

Once mature, the weight of the underground bulb is between 10-25 pounds.
