Plants from this species ...

... are of excellent ornamental value
In Metro Manila in Philippines they need average care and grow fast.
You can expect a bit of variation from hybrids but these are all generally easy to care for once you have given them the basic requirements for any cycad-- free draining medium. I have not really tested their sun tolerance but the substance of the leaves look a bit tougher than Debaoensis. I have unintentionally left them dry but they fared pretty well and showed no signs of stress. I don't observe any hybrid vigor though and these actually grow slightly slower than C. Debaoensis (which I consider a very fast grower). I have been looking out for multipinate leaflets and so far only 40% came out with split leaflets. These multipinnate leaflets only started coming out on the seedlings 6th or 7th leaf, which is about 9 months from sprouting. Most still have simple leaflets but there is a possibility that they will also split later on, I think. There is notable variation of leaf forms in the ones I got - so this is a pretty exciting cross. So far I have been growing them in pots under 65% shade cloth but I am in the Tropics. We water these every other day. The soil mix is loose and free draining( lots of perlite mixed in)

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.
