HARDY SAGO PALM Cycas revoluta
These palm are very hardy, zones 8-10! We first saw them growing in a nearby garden in Kitchener, Ontario! The front garden of the home was planted with massive and amazing hardy tropicals, and we were honored to be able to speak with the home owner/gardener! He told us how this palm is overwintered, in a light wooden frame covered with plastic, and Christmas lights inside to hold the heat, which we also saw many times on our evening walks! See the image attached of the Kitchener garden (photo with red car)!
Cycas revoluta, sago palm, king sago, sago cycad, Japanese sago palm, is an ornamental plant, very symmetrical and supports a crown of shiny, dark green leaves on a thick shaggy trunk that is typically about 20 cm (7.9 in) in diameter, sometimes wider. The trunk is very low to subterranean in young plants, but lengthens above ground with age. It can grow into very old specimens with 6–7 m (over 20 feet) of trunk; however, the plant is very slow-growing and requires about 50–100 years to achieve this height. Trunks can branch several times, thus producing multiple heads of leaves.
The leaves are a deep semiglossy green and about 50–150 cm (20–59 in) long when the plants are of a reproductive age. They grow out into a feather-like rosette to 1 m (3.3 ft) in diameter.
As with other cycads, it is dioecious, with the males bearing pollen cones (strobilus) and the females bearing groups of megasporophylls. Pollination can be done naturally by insects or artificially.
Propagation of Cycas revoluta is either by seed or clonally by removal of basal offsets. It is one of the most widely cultivated cycads, grown outdoors in warm temperate and subtropical regions, or under glass in colder areas. It grows best in sandy, well-drained soil, preferably with some organic matter. It needs good drainage or it will rot. It is fairly drought-tolerant and grows well in full sun or outdoor but needs bright light when grown indoors.
C. revoluta is seen in almost all botanical gardens, in both temperate and tropical locations. It is tolerant of somewhat cold temperatures, provided the ground is dry. Frost damage can occur at temperatures below −10 °C (14 °F). C. revoluta may defoliate in winter in this temperate climate, but will grow new leaves by spring.
This plant has gained the Royal Horticultural Society's Award of Garden Merit.
Cycad sago is extremely poisonous to animals (including humans) if ingested. Pets are at particular risk, since they seem to find the plant very palatable. If any quantity of the plant is ingested, a poison control center or doctor should be contacted immediately. Effects of ingestion can include permanent internal damage and death. All parts of the plant are toxic; however, the seeds contain the highest level of the toxin cycasin.
These seeds are extremely large, like small golf balls!
Seeds per pack: 3
Germination: Soak the seed in water for 4-5 days, then remove the red skin but leave the white seed coat. The seeds should be planted horizontally with the top edge exposed above the soil surface. Most of the Cycas revoluta seeds will germinate successfully, though they often take 3-9 months to do so. Patience is always required with Cycads due to their slow growth rate.
