Parajubaea cocoides

Mountain Coconut, Cocumbe Palm

This much talked about palm is erratic to germinate; it does best if seeds are dried for several months before sowing and then placed on the soil surface, not buried more than halfway. Once sprouted, it is fast growing, very adaptable, and resembles nothing so much as a coconut palm, or a huge Lytocaryum weddellianum. BUT, it's cold hardy! For a wonderful account of this stunning palm see PRINCIPES Vol. 31, pages172-176. An absolute must for all cool temperate and mild subtropical areas!

... are easy to germinate and need up to 3 months to sprout.
Parajubaea cocoides doesnt deserve its reputation for having a low germination rate. I achieved a germination of nearly 100% (well,one seed had been damaged for some reason at one pore and rotted...) using the following method: I soaked the seeds i received, which were very dry and made sound if shaken, in water for a bit more than a week, till they stopped making noise and sowed them on pure perlite. In a month or a bit more, the first seed send a taproot and i removed it. Then,withing the first 3 months, other two germinated and were planted to deep 30 cm pots. Within one more month another one germinated and was kept in perlite in a deep diy pot i made and was kept for more that a month there and completely developed its first leaf (only a bit dwarfed). The rest of the seeds showed no germination at the following months. Because i was entering a buse period in my life, i decided to prepare the seeds for long storage so i soaked the in water for a few days and then left the outer shell dry and placed them in the ziploc bag they came and left them in that condition for a year. Then, i soaked them again in water and placed them at their old perlite. In less than a month they started to sprout and all but one(the one that was damaged) germinated within 1 month and a half. So, from my experience, doing what they require which is a long dormancy period, and a lot of patience is all thats needed to achieve good germination results from this wonderful palm. As a seedling, from my experience is extremely sensitive to normal watering and to keeping their soil just moist, they just rot....But if you water only when the soil has dried on the surface 1-2 cm and water little, to keep the deep of the pot just moist, they are undemanding and grow quite fast. Something very good is that they can take full sun from the first leaf, no scorching, no sign of damage! Also they are very tolerant of being moved from shade to full sun, they adapt quickly and the shade leaves dont show much damage. Also they appear to be left alone by most pests. Good luck with them!!!

...not rated.
I here that it is better to plant these in the location you want to plant the tree because transplanting them at a young age is very very hard to do and damaging the main root is usualyl fatal, just make sure the location is irragated and a small fence so no one would step on it. They germinate easier when in cooler conditions rather than warm.

...very difficult to germinate and need more than 1 year to sprout.
I tried different ways, but only one was good: I leave the seeds in a big pot where grows a 20 years old kentia, in my office, after 3 months one seed sprouted, after more than a year the other two did.

...easy to germinate and need up to 3 months to sprout.
I took the chance of removing the shell from the kernel of several seeds. This was not a easy task, requiring a heavy hammer and a concrete floor and being very careful not to crush the kernel while still being able to crack open the shell. After this, the naked kernels were half buried in moist peat moss in pots and the pots were placed in Ziplock bags. Germination was about 2/3 within 2 months. None of the naked kernels rotted, but some did not sprout even 6 months later.

...easy to germinate and need up to 3 months to sprout.
Out of a batch of 10 seeds I cracked 4 from their shells, with great difficulty. They all rotted.I soaked the rest in tap water at room temperature for a few days and bagged them up with moist vermiculite and shoved them in my airing cupboard. Within 3 months 3 had germinated and are each sending up shoots. If kept warm they grow very quickly.2 of them I left in my cool greenhouse and they stopped doing anything only to return to activity when returned to warmth. The remaining three look fine. I think cracking them is a waste of time and seedsand in my hands the same is true of Jubaea seeds.

Filled open container with Canadian peat/Perlite mix and pressed seeds on side half into medium. Then covered with 3 inches of moist Canadian Spagma moss. Kept moss moist for 8-12 weeks with 40% germination at 12 weeks. Others still appear viable.

...difficult to germinate and need more than 1 year to sprout.
Reputated very difficult, but not so hard indeed. I have got 60% in the first year and the remaining seeds are stiil good.I have used a polystirol box with lid, filled with moist perlite, putting seeds half buried with the tip down. Box was kept on the upper level of a shelve in greenhouse with natural summer heat. Germination have started after 4 months, continuing just one from time to time for an year.

Germination starts within a month but a whole batch may take two or more years to all germinate, if at all.

...difficult to germinate and need up to 3 months to sprout.
Best at room temperature. 21C (70F). Reputation for erratic germination well-deserved. Some will sprout in a week others take up to 3 years. Best to resist the temptation to break off the shell as they are very likely to rot. Sow in sterile medium and check weekly for signs of germination.

...very difficult to germinate and need more than 1 year to sprout.
These little mini-coconuts Are dry to bone when arrive, soak shell and all in potassium nitrate for two days, " carefully crack shell with hammer and visegrips. Next take endosperm seed and place in peat in ziplock freezer bags, ( peat has been treated with horms superthrive according to directions). Place freezer bags on ventilated rack in front of south or west facing window, sliding glass doors, will germinate within 2 weeks if kept warm. Ps careful not to scuff or nick endosperm, will result in rotting of seed. Good growin to all.

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.
