Description
Ilex cassine is an evergreen Tree growing to 10 m (32ft 10in) at a slow rate. See above for USDA hardiness. It is hardy to UK zone 6. It is in leaf all year, in flower from May to June, and the seeds ripen from October to February. The species is dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). and is pollinated by Bees. The plant is not self-fertile. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
Edible Uses
Tea. The dried roasted leaves can be used as a tea substitute. Some caution is advised since it can cause dizziness and have a laxative effect.
Medicinal Uses
Emetic Hypnotic Laxative. The leaves are hypnotic and laxative. A strong decoction of the plant was used by some native North American Indian tribes to induce vomiting. This was seen partly as a physical and partly a spiritual cleansing.
Known Hazards
Although no specific reports of toxicity have been seen for this species, the fruits of at least some members of this genus contain saponins and are slightly toxic. They can cause vomiting, diarrhoea and stupor if eaten in quantity.
Distribution
South-eastern N. America - Virginia to Florida, west to Texas.
Where It Grows
NORTHERN AMERICA: United States (Alabama (south), Florida, Georgia (south), Louisiana, Mississippi (south), North Carolina (east), South Carolina, Virginia (southeast), Texas, Mexico (Veracruz de Ignacio de la Llave) SOUTHERN AMERICA: Bahamas, Cuba, United States (Puerto Rico (northeast))
Cultivation
Tolerates most soils that are not water-logged. A slow-growing and generally short-lived species in the wild. Resents root disturbance, especially as the plants get older. It is best to place the plants into their permanent positions as soon as possible, perhaps giving some winter protection for their first year or two. Flowers are produced on the current year's growth. Plants are very tolerant of pruning and can be cut right back into old wood if required. Dioecious. Male and female plants must be grown if seed is required.
Propagation
Seed - best sown as soon as it is ripe in the autumn in a cold frame. It can take 18 months to germinate. Stored seed generally requires two winters and a summer before it will germinate and should be sown as soon as possible in a cold frame. Scarification, followed by a warm stratification and then a cold stratification may speed up the germination time. The seedlings are rather slow-growing. Pot them up into individual pots when they are large enough to handle and grow them on in light shade in a cold frame for their first year. It is possible to plant them out into a nursery bed in late spring of the following year, but they should not be left here for more than two years since they do not like being transplanted. Alternatively, grow them on in their pots for a second season and then plant them out into their permanent positions in late spring or early summer. Give them a good mulch and some protection for their first winter outdoors. Cuttings of almost ripe wood with a heel, August in a shaded position in a cold frame. Leave for 12 months before potting up. Layering in October. Takes 2 years.
Other Uses
Soap Wood. The plant has been used as a soap. No more information is given. Wood - soft, light, close-grained, not strong. It weighs 30lb per cubic foot. Of no commercial importance.
