Cycas ophiolitica

Marlborough Blue Cycad

An excellent Australian species with glaucous to powdery blue leaves. It can be grown in warm temperate to tropical areas but prefers hot, dry inland conditions and low humidity. Heavy soils (serpentine) with excellent drainage and a place in full sun will produce optimum colour.

... are difficult to germinate and need up to 3 months to sprout.
I have not had a great deal of success with germination of Cycas ophiolitica! I received ten seeds (from another reputable supplier) and after the customary soaking for a few days, it became very obvious that most of them were not in viable condition. The supplier kindly sent me some replacements, and I do at least now have a couple that are doing what they should and have been planted outside into pots. One of these seeds decided to sprout its radicle INSIDE the sclerotesta (shell), which is a trick to look out for!

...easy to germinate and need up to 3 months to sprout.
Easy to sprout and grow on if temperatures high enough. Soaked 2-3 days in warm (80F / 25C) water changed daily. Then to baggies with barely moist coconut fiber kept at 30C / 90F. Transplanted to pots with loose soil mixture when shoot 1 inch / 2.5cm long and not allowed to dry. Tolerates much sun.

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.
