Cycas debaoensis
Multipinnate Cycad

Discovered and described as recently as the late nineties, this extraordinary cycad is only known from a single small area in western Guangxi, China, where it grows in mixed evergreen and deciduous forest on steep limestone slopes. Like so many cycads, it is highly endangered through destruction of its habitat and the collection of its trunks for horticulture. While its trunk is short and subterranean and only about 20 cm (8 in.) in diameter, its four to ten bipinnate leaves are probably the most fantastic among the cycads and readily distinguish it, and the very similar Cycas multipinnata, within the entire genus. The leaves are deep green, glossy, and can reach an amazing 2.5 to 3 m (8 to 10 ft.) long. The 30 to 50 leaflets are around 55 cm (22 in.) long and branched into numerous "fingers," giving the leaf a very full and bushy appearance. This species is undoubtedly the most desirable in the genus and we believe this to be its very first general introduction into horticulture.
For a great picture and some background information, we recommend Ken Hill's "Cycad Pages".
Our seeds are individually tested and selected, ready to germinate, and should produce nearly 100% germination.

Seeds from this species ...

... are easy to germinate and need up to 3 months to sprout.
Germination technique like that for Cycas multipinnata: seeds were soaked in water for 24 h. A hole was cut in the outer seed coat to expose the point were the developing embryo would emerge. The seeds were placed horizontally in a shallow plastic tray (2 cm deep) which had been filled with perlite. The perlite was wet with water (to make it moist, not saturated). The tray was placed in a propagator that was heated to 25 degrees Celcius with the vents open. Shoots emerged from 60% of the seeds within 4 months. Like many cycad species, much of the first year of growth occurs underground. Seedlings should be potted up in perlite alone (addition of compost can cause water retention and root rotting - this applies to the 20+ varieties of cycad I have grown from seed bought from Rare Palm Seeds). Place individually potted seedlings on a south-facing window. I sowed the seed in January 2007 and now the seedlings are responding to the sunlight, some producing their first leaf. The leaflets fork in the second or third year of growth according to the experts, so do not be disappointed in the first year! Be patient and you will be rewarded with a very special and beautiful plant. Once again, the quality of seed supplied by Rare Palm Seeds was excellent.

... are easy to germinate and need up to 1 month to sprout.
100 seeds from rarepalmseeds last winter. Soaked 3 days, placed on top of 10" of perilite with 1" of vermiculite on top for the moisture retention inside a 40 gallon cooler in the garage, seeds burried 1/3rd into the vermiculite and kept moist not wet. kept above 65 degrees (f) with days reaching 75-80. First germination within a week, Finished with close to 80 percent germination.Same results with Multipinnata........

... are average to germinate and need up to 3 months to sprout.
This cycad seed is quite easy to germinated but quite easy to rot because of its small size so if too much humidity then the seed will damage. Soak the seed in water for 2 days but only 12 hours each . Used sand and peat moss . Check the seed every weekend . First seed will germinate aroud 6 weeks later.

... are very easy to germinate and need up to 1 month to sprout.
Very easy to germinate.Soaked 100 seeds in warm water for 2 days(changing water daily). Placed seeds in large clear plastic tub with lid filled with a perlite/vermiculite mixture. Misted with water to keep moist. Room temperture at 82 degrees. I had 25% germination in 4 days , 50% @ 2 weeks and 65%@ 3 weeks(present). I expect atleast 90% germination.

Got 20 seeds and placed in ziplock with 75% perlite, 25% cocofibre.Kept at about 85 degrees. 18 have germinated within 1 month and 10 have sprouted.

...easy to germinate and need up to 3 months to sprout.
Seeds half buried on 3" of perlite in a large, covered, undrained tupperware. Perlite kept moist, but not so much that the seeds were in standing water. Bottom heat was provided with a heating pad, 30 minutes on, 30 minutes off. So far have 50% germination after 2 months.

Plants from this species ...

... are of excellent 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. Debaoensis, Dianensis, and currently Multipinnata treated the same with exact same results.

Ratings and comments reflect individual experiences and the views of our visitors. They do not necessarily describe the most appropriate methods, nor are they necessarily valid for all seeds or plants of this species. Germination and plant cultivation success depends on many different factors; nevertheless, these experiences will hopefully aid you in your effort to get the best germination results from our seeds and the best growth results from your plants.

Martius, Book of Palms
by H. Walter Lack

Hardcover - 450 pages

11.1 pounds!
50 x 34 cm, 5 kg

Our Rating:
Suitable for: all

Martius's magnificent work on the varieties of palm tree. This epic folio was based on Martius's expedition to Brazil and Peru with zoologist Johann Baptist von Spix. From 1817 to 1820 the pair travelled over 2,250 km (1,400 miles) throughout the Amazon Basin, the most species-rich palm region in the world, collecting and sketching specimens.
In his epic work, Martius outlined the modern classification of palm, produced the first maps of palm biogeography, described all the palms of Brazil, and collated the sum of all known genera of the palm family. For apart from his own collection of specimens and notes, Martius also wrote about the findings of others.
Martius's folio is unusual in its inclusion of cross-sectioned diagrams, conveying the architecture of these mighty trees. Equally remarkable are the color landscapes showing various palms—often standing alone—which have a simple and elegant beauty. This famous work is an unrivaled landmark in botanic illustration and taxonomy.
