Only a few bulbs produced flowers with the attractive characteristics of their parent plants.

Each bulb produced a single stem of beautiful purple-throated white flowers.

What you cannot see is the ultraviolet light that the bulb is also producing.

The bulb also may produce offsets, which can be removed while the plant is dormant.

A bulb must produce at least four large, healthy leaves in the summer growing season before it can send up a scape the following year.

Each bulb produces only two leaves, which appear with the flowers and normally spread out along the ground on either side.

These bulbs quickly burned out, and, even while functioning, never produced a clear recording.

A fluorescent bulb produces less heat, so it is much more efficient.

Without adequate sun, the bulb will produce leaves but not flowers.

Each bulb produces only a few leaves, which are thick and grooved.
