...easy to germinate and need up to 3 months to sprout.
Seed was given to me by a friend in Tropical Queensland, Australia. They arrived fresh and I removed the outer flesh and gave them a quick rinse to remove pieces of flesh that might possibly cause fungus problems during germination.Seed was planted in a 15cm deep pot, 5cm under the surface of a good quality organic potting mix. In retrospect, I should have used a deeper pot as this species sends down a long tap root. After 1-2 months the radicle had started to emerge. Another 1-2 months and it was sending up a shoot. Almost 9 months after germination it has leaves.A beautiful looking palm species that may also have been used as a Betel Nut subsitute in the Solomon Islands.

...very easy to germinate and need up to 1 month to sprout.
I ordered 10 seeds, 6 of them were already germinated upon arrival (the seeds are huge, roughly the size of Wodyetia, perhaps a bit larger). 1 seed rotted, and 1 germinated later in a 1 gallon nursery pot in the heat of a Central Florida summer (hot). 1 Seed never germinated. Of the 8 that germinated, 3 died, the other 5 are growing strong. First leaf is bifid, as are the next several. Leaves seem to gradually become pinnate, and each new leaf and petiole are considerably larger/longer than the previous. Initially the seedlings seem to prefer deep shade, and the leaves easily become pale to yellow.

Plants from this species ...

... are of excellent ornamental value
In Yeppoon on the Tropic of Capricorn. QLD in AUSTRALIA they need average care and grow fast.
Young plants with large leaves need shade and wind protection for the first year or two. After that they adjust to higher light levels, eventually emerging into full sun and some coastal wind exposure. I keep these moist and well mulched with plenty of organic material and an occasional feed with cow manure. Once a year I dose them with trace elements. Here some of my palms suffer from magnesium deficiency so I give a general trace element treatment to all my palms. These are very nice upright young plants. Next summer I expect them to grow very fast. Mealy bugs in the leaf axils and scale on the underside of leaves in young plants are a problem. I spray and scrub them with a pure soap and water solution. If you have ants on them you will definitely have mealy bugs and/or scale.

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.
