Johannesteijsmannia altifrons

Surely one of the most stunning and spectacular palms in the world, J. altifrons has large, simple, undivided leaves that can reach a length of more than 6m/20ft, rising directly from an underground rootstock. These huge, very leathery, roughly diamond-shaped leaves are pleated along their length, giving the most bizarre appearance. The Joey grows in montane rainforest in S. Thailand, peninsular Malaysia, Sumatra, and Borneo, at up to 1200m (400ft). It is much tougher and more cool-tolerant than one might expect, and will grow happily in the subtropics and of course any tropical climate, in a shady, wind protected situation. It has been proven to do well, for instance, in coastal S. California, S. Spain or S. Florida, and can even be kept as a striking indoor plant. We now have a very fresh lot of the peach-seed-sized seeds of this much sought-after plant available at very attractive prices.

... are average to germinate and need up to 6 months to sprout.
Joey are not that difficult, however, they take a long time to germinate. I'm into my 3rd batch. The first batch I placed in zipper bags with moist sphagnum and now (my 3rd batch) all seeds have been placed in moist coir after checking for cracks in the outer shell. If it's cracked it has to be removed or the seed is very likely to rot. After 2 month the first sprouts appear (on average among my seeds). Growth is extremely slow, one of my seedlings is almost a year old and is currently working on its second leaf!! One comment about containers: they have to be very tall to accomodate the radical, Joeys are remote germinating! Careful when transplanting, apparently the roots don't like to be disturbed.

...difficult to germinate and need up to 3 months to sprout.
Erratic germination experiences here. Only one has put started to germinate. However, no leaf has surfaced. Still monitoring.

...very easy to germinate and need up to 1 month to sprout.
I placed 10 seeds in water for 2 days. One seed rotted. I then placed the 9 remaining seeds into a large "zip lock" bag filled with vermiculite, perlite, and peat moss and left it open for ventilation. I misted the medium as to be moist but not dripping. Eight days later 7seeds had germinated, and one more a week later. Temperatures were mid 80's to low 90's, unusually high for February-even in south Florida.

...difficult to germinate and need up to 3 months to sprout.
Three of ten seeds -acquired here- germinated after three month,the others rotted. One day presoaking, climate chamber @ 30°C, used Kokohum moist. Now, 7 month after germination, they have one leaf of 30 cm height,the second appears (~10 cm). Does well in shadow near south-window (shadow by Bananas and Cocos), but grows slowly. First I had them in my tropical climate chamber, but they didn't liked it(too much sun ?)Image available on request.

Suitable for: all

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.
