The Chlorogalum plant is grown as a hardy bulb.
It is a tall plant with long green-grey leaves, and grows from 60 cm to 2.5 metres (2 to 8 feet) in height.
It blooms at the beginning of Summer, with white, blue, or pink terminal flowers.

Interestingly, Chlorogalum plants only bloom in the afternoon. Some of the common names that they are known by includeSoap plant, Amoles, and Soaproot.
The bulbs of the Chlorogalum plant should be planted at a depth that is about twice their size.
If planning to sow from seeds, then Soap plant seeds should be chilled by placing the seeds in pots (with soil) in a black bag, then placing in the fridge for two weeks.
The pots should then be planted outdoors, buried to the rim in the spring-time.
Once seedlings appear, they should be transplanted at a spacing of about 7 to 10 cm (3 to 4 inches) into a sunny or partially shaded part of the garden. This location should have good drainage.
The ideal soil for growing Chlorogalum plants should be fertile. Plants should be kept moist by watering, and cut back following flowering.
The Chlorogalum genus includes around six species, such as the Soap Plant or Amole.
Chlorogalum species aren't commonly grown in gardens, but they can add interest to native plant or wildflower gardens.
Chlorogalum pomeridianum, also known as Soap Plant or Amole, is sometimes grown for its interesting flowers and ethnobotanical history.
Chlorogalum pomeridianum has fragrant, evening-blooming flowers that attract pollinators like moths.
Chlorogalum prefers sunny locations with well-drained soil. It's a drought-tolerant plant perfect for California native plant gardens.
Currently, Chlorogalum is not considered invasive in the USA. It's a North American native plant, particularly in California.
To remove Chlorogalum, dig out the large bulbs, ensuring that all bulb fragments are removed to prevent regrowth.
The Chlorogalum genus, part of the Asparagaceae family, is native to western North America. Also known as soap plant or amole, these perennial bulbous plants are recognized for their grass-like leaves and tall stalks of small, star-shaped white or purple flowers that bloom in summer.
To grow Chlorogalum, plant them in a sunny location with well-drained soil. They can be grown from seeds or bulbs. Regular watering is necessary, but they are quite drought-tolerant once established. They are often used in meadows, borders, or as cut flowers for their attractive, starry blooms.
