...very easy to germinate and need up to 1 month to sprout.
I sowed 10 seeds I had ordered from here in a 50/50 mix of sphagnum peat and perlite after having soaked the seeds for 3 days in warm water (with daily changes). Germination was rapid with all 10 having germinated within 2 weeks. As opposed to other attempts at germinating this species, this time I actually got 7 of the 10 to live past a week. These will succumb to fungal infections very easily. Keep the temperature for the seeds around 80f/27c. The first leaf is finely pinnate. This species produces a significant root system in relation to the above ground growth. When potting the new seedlings up, make sure to use a large enough container.

...very easy to germinate and need up to 1 month to sprout.
Ordered 10 seeds from Rare Palm Seeds on 19 Feb 04; received packet on 15 Mar 04; soaked in water with a bit of fungicide for 2 days; placed in plastic zip lock plastic bag with peat moss moistened such that no water could be squeezed out by hand. Kept at constant 30C; 1st sprout in 11 days; potted in half potting soil and half sand; kept at 30C and first leaf emerged at 37 days from soaking.

This is by far the fastest palm I have ever germinated. Most seeds already shown sign of germination while soaked in water for three days. Seeds develope quickly a thick root and the first leaf, already pinnate, will emerge in a matter of few weeks.

...very easy to germinate and need up to 1 month to sprout.
Very easily germinated seed but also very prone to fungal disease. Soak for a day in fresh water with some fungicide added. Some seeds will germinate during this time!Other seeds perish quickly after this due to fungal growth and temperature does not seem to be a feature as long as it above 21C (70F)

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.
