Chlorogalum pomeridianum - (DC.)Kunth.
                 
Common Name Soap Lily, Wavyleaf soap plant
Family Hyacinthaceae
USDA hardiness 7-10
Known Hazards The bulb contains saponins. Although fairly toxic, these substances are very poorly absorbed by the body and most of them simply pass straight through. Saponins are found in a number of common foods, including many beans. They are destroyed by thorough cooking[K]. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[K].
Habitats Dry open hills and plains, occasionally in woods, below 1500 metres[71].
Range South-western N. America - California.

Physical Characteristics
 icon of manicon of bulb
Chlorogalum pomeridianum is a BULB growing to 2 m (6ft) by 0.3 m (1ft in).
It is hardy to zone (UK) 8 and is not frost tender. It is in flower from May to June. The flowers are hermaphrodite (have both male and female organs)Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Synonyms
Loathoe pomeridiana.

Habitats
 Cultivated Beds; East Wall. By. South Wall. By. West Wall. By.
Edible Uses
Edible Parts: Leaves;  Root.
Edible Uses:

Bulb - cooked[2, 71, 94, 105]. A slow baking in its skin will remove any soapiness in the taste[92]. The bulb should be peeled before being eaten since the skin is fibrous[183]. The bulb can also be peeled and then boiled, though the water it is cooked in should be thrown away[94]. Although wholesome and nutritious when thoroughly cooked, the raw bulb should not be eaten because it contains saponins[K]. The bulb is very large and can be up to 15cm in diameter[200]. Young leaves - raw or cooked[105]. Used as a potherb when harvested in the spring, they are very sweet when slowly baked[92, 183, 257].
Medicinal Uses


Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Antidandruff;  Antirheumatic;  Antiseptic;  Diuretic;  Laxative;  Poultice;  Skin.

Soap lily bulbs contain saponins, a medicinally active ingredient that is of particular value as an antiseptic wash. Saponins are somewhat toxic (see the notes above on toxicity) and so any internal use of this plant should be carried out with great care[K]. The bulb is antiseptic, carminative, diuretic and laxative[94, 257]. A decoction has been used to treat wind in the stomach[257]. Externally, the bulbs have been rubbed on rheumatic joints[257]. The pounded bulbs were mixed with water and used as a hair wash in the treatment of dandruff, to prevent lice and also to treat skin irritations including that caused by poison oak[213, 257]. A poultice of the baked bulbs has been used as an antiseptic on skin sores[257].
Other Uses
Adhesive;  Fibre;  Soap.

A glue can be made from the sap that is expressed from baking bulbs[92, 94, 257]. The bulbs can be boiled into a liquid starch which can then be used to twined baskets to close the interstices so that seeds do not fall through[257]. A soap is obtained from the bulb[21, 46, 61, 169]. The bulb is stripped of its outer fibrous covering and rubbed on clothes or hands in water to produce a lather[92, 95]. It is very good for delicate fabrics and has a gentle affect upon the skin[92, K]. The bulb can also be dried for later use, it can then be grated as required and used as soap flakes[92]. A fibre obtained from the outer covering of the bulb is used to make small brushes or as a filling for mattresses etc[92, 94, 169, 257].
Cultivation details
Succeeds in any reasonably good well-drained soil[1, 42]. Prefers a rich well-drained moisture retentive soil[164]. Tolerates partial shade[164]. Dislikes dry soils according to one report[200] but plants grow in dry soils in the wild[71]. Plants are frost hardy but they come into new growth in the autumn and so need to be grown in a warm sheltered position, especially in colder areas of the country[188]. The bulbs can be damaged by heavy frosts[169]. The roots are brittle so any transplanting should be done with care[169].
Propagation
Seed - sow spring or summer 2mm deep in a peat/sand mix. Germination usually takes place within 1 - 6 months at 15°c, but it can be slow and erratic. Sow the seed thinly so that the seedlings do not need to be thinned and grow them on in the pot for their first year of growth, giving an occasional liquid feed o ensure that they do not become mineral deficient. When dormant, pot up 3 young bulbs per pot and grow them on for at least another 2 years before planting them out into their permanent positions in the spring[164]. Division of offsets when the bulb dies down in late summer. Larger offsets can be planted out direct into their permanent positions but it is best to pot up the smaller bulbs and grow them on for at least a year in the greenhouse.

I liked your article, it gave alot of information I needed. Please note that the "Soap Lily" as you described is also Amole, Soap Plant, and Soap Root. It was also used by the Miwok as a fish poison (I can't remeber if you said this though). It would be placed in water where alot of fish were, the chemical within the plant would shock the fish allowing the Miwok to gather the fish that floated to the top of the water without so much hassle. You can't do that now with Soap root, it's illegal, but that's what the Miwok did. This information was by Nancy Kissam from Kule Loklo in California.

Plant description for chlorogalum pomeridianum says no weed potential. On my Southern Oregon property it is extremely invasive, with the population doubling annually. They are nearly immune to removal (some as much as 16 inches deep), frost (all survived a week of single digit temps in 2013) and strong herbicides (like brush killers that decimate poison oak). Breaking the woody seed stalks before bloom did little to reduce the spread, and they are rapidly becoming the dominant plant on my hillside forest property, currently numbering in thousands, soon to become tens of thousands. PFAF has the best available plant description, but I've found no website that can suggest a means of stopping their spread.
