Cycas diannanensis

This cycad was discovered only a few years ago growing on limestone slopes in cloud forest to 1200 m (3900 ft) along the Red River in China's Yunnan province. It develops a short trunk to 3 m (10 ft) tall and an upright crown of large, bright green leaves with up to 300 wide, undulate leaflets. The large seeds are easy to sprout and seedling growth is fast.

Seeds from this species ...

... are easy to germinate and need up to 1 month to sprout.
They sprouted in less than a month! I left the seeds half soaked in water with bottom heat until they started to crack (about 10 days). The water should be changed twice a day. Once they cracked open, I carefully removed their hard shell. Quickly after, their root started to grow. I sprayed them with organic fungicide once a week. When the root was about an inch, I removed them from the clean water and planted them in prepared sterile soil for cacti. So far so good. 6 seeds out of 10 sprouted. The process after the cracking and the root coming out, has been looong but worth it. The huge soft ball of the seed still is there between the root and the new leaves finally growing (thought they never will).

...easy to germinate and need up to 3 months to sprout.
Easy to germinate. Soak in water a couple of days. Then placed on perlite with bottom heat and kept moist. 4 of 10 sprouted in 2 months. I expect a few more to come out.

Plants from this species ...

... are of average ornamental value
In San Francisco in USA they need very little care and grow slow.
I grow both seedlings and young plants outdooors in pots near the ocean in foggy San Francisco. The grow well and seem to put up leaves at any time of year; usually more than one flush per year. They were making a round of new leaves last winter when we had near-freezing temperatures, and only one leaf on one plant was slightly damaged. I recommend this species for trials in cool climates.

... are of high ornamental value
In San Diego in USA they need average care and grow slow.
Germinated seeds placed in 9" bands in mix of fine orchid bark, pumice, and palm soil mix in 1/1/.5 by volume. Fertilized regularly with a liquid 8-8-8 orchid mixture and growing at the expected rate for most Cycas species. Now almost 1 year, minimal loss to root rot (3 plants, 2 recovered after treatment) plants are on 3-4th leaves and .75" dia caudexes average currently. Grown outdoors in San Diego in 1/2-3/4 day full 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.
