Nothing to it. I removed the fruit flesh. In early April I placed fresh seeds about 8 cm deep where I wanted them to grow in the landscape. I placed the seeds with what seemed to be the bottom end down. They germinated by mid-summer, with one germinating in September. I think only one didn't germinate.

... are easy to germinate and need up to 6 months to sprout.
Put seeds in plastic baggies of moist seed starter mix. Kept in a warm place in the house where they sprouted in about 4 months.

... are very easy to germinate and need up to 3 months to sprout.
I first soaked the seed for 10 days with water with 1/4 teaspoon captan fungicide,then drained and soaked seed 2 days in clean water. Then put seed in baggie with peat moss soaked in captan water. squeezed excess water and seed started sprouting in three weeks and 90% was sprouted in 6 weeks. It is best not to turn seed over as it starts sprouting, as it disorientates the sprout and makes it harder to plant.

...very easy to germinate and need up to 3 months to sprout.
I soaked the seeds in luke warm water for 3 days (changing daily). Than press the seeds 2/3 of the way into the soil, I used peat + perlite (50:50), temperature was about 90°F/30°C. First seed sprouted after 26 days and all five had germinated after 45 days.

Plants from this species ...

... are of high ornamental value
In Southampton in England they need very little care and grow fast.
This plant require very little care and grows relatively fast by cycad standards. I grow mine in a pot, which is moved outside in summer and into my heated greenhouse in the winter. I did try to grow this species outside here in southern England, however the species, although tolerant of a few degrees of frost, could not take the wet of the English winter and I lost one plant, and another is still struggling to recover years after. Therefore overwintering in a greenhouse seems essential in cold/wet climates. Under the right conditions however, this species is one of the easiest to grow. Both drought tolerant and tolerant of temperatures down to at least -2c for short periods. I use a very free draining cactus compost in a deep pot, to allow depth for initial root growth after germination. I water fairly regularly in summer, allowing a brief drying between watering, but more sparingly in winter, allowing lengthy dry periods. This species is very accomodating though, and only really struggles when conditions are persistently extremely unfavourable. Seems to tolerate both full sun and a fair degree of shade. Good as a houseplant to, in a bright spot. Probably the easiest cycad species to grow, and the one you're most likely to see in England!

The Encyclopedia of Cultivated Palms is the definitive account of all palms that can be grown for ornamental and economic use. Palms are often underutilized as a result of their unfamiliarity—even to tropical gardeners. To help introduce these valuable plants to a new audience, the authors have exhaustively documented every genus in the palm family.
825 species are described in detail, including cold hardiness, water needs, height, and any special requirements. Generously illustrated with more than 900 photos, including photos of several palm species that have never before appeared in a general encyclopedia, The Encyclopedia of Cultivated Palms is as valuable as an identification guide as it is a practical handbook. Interesting snippets of history, ethnobotany, and biology inform the text and make this a lively catalog of these remarkable plants.
