Cycas thouarsii

This cycad not only is one of the largest species in the Cycadales but is probably also the oldest, having been around for a possible 140 millon years, and undoubtedly is the fastest growing cycad. 60cm (2ft) in its first year from seed is the rule and will make up for the large seeds being somewhat lengthy to germinate. We can now offer this species at a sensationally low price.

...easy to germinate and need more than 1 year to sprout.
Incubated six seeds in moist vermiculite at around 30C One germinated after 6 months. I was told that germination can take around 18 months. Planted the first seed in a mixture of kokohum, sand and perlite.

...difficult to germinate and need more than 1 year to sprout.
Lengthy germination time is an understatement. First seed germinated after 1 year and others are continuing after year and half. Best to leave pointed side down 1/3 submerged into soil. No heating or plastic covering will help. Its actually better to not cover with plastic or baggie method with most cycads as they do not need or like this type of dampness or humidity.

...easy to germinate and need more than 1 year to sprout.
This species is quite peculiar in its requirements in germination. It takes a very long time, one years is the rule. Probably the embryo need more time to develop completely, because the seeds are very large. Would be better to don't sow soon the seeds, but store them in vermiculite or peat, just slightly moist, for several months. Then, precede in the usual way. However, rate is satisfactory; just you have to be patient.

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.
