[Overview]
A bulbous perennial.
The leaves arise from the base and are strap-shaped.
There are winter-flowering and summer-flowering species.
An umbel at the tip of the flower stalk bears several flowers.
[Cultivation]
Propagate from seed or by dividing the bulbs.
It can overwinter outdoors in regions without frost.
In a sunny, well-drained site it grows well regardless of soil type.
Some species dislike heavy fertilizing and excess moisture.
Take care not to overwater; for potted plants, water thoroughly after the soil has dried, and for plants in the ground, rainfall is sufficient.
Fertilize sparingly; if base fertilizer is applied, none further is needed, but slow-release fertilizer may be applied once a month from spring to early summer.
There are no particular pests or diseases.
