PARAJUBAEA TORALLYI THE SOUTH AMERICAN "COCONUT PALM" PRESENTLY IMPOSSIBLE TO FIND AVAILABLE

This morning I thought I’d talk about this South American palm and include a fair amount of information. I’m doing this because I’ve found there is often confusion with the genus “Parajubaea“. I included the common name of “South American Coconut” for this genus because the new palm enthusiast will most likely forget these long winded scientific names. I particularly want to emphasize P. torallyi because I think it’s such a great plant and easy to grow. It has two forms.

Parajubaeas are all from South America. About twenty years ago the genus was:”reborn” with the importation of seeds of various species from habitat. Enthusiasts had to learn more because they had “new plants” in front of them. Also, this gave palm people the opportunity to grow all of the species. There are three species and one sub-variety. These are Parajubaea cocoides, sunkha, and torallyi. Parajubaea torallyi has a sub-variety named P. torallyi variety microcarpa. P. cocoides has historically been the species that people have grown for the longest period. This species is a bit different appearing than all the others with greener leaves and slower growth. The other three types of Parajubaeas began their notoriety when seeds began being imported. The seeds are very large (hence the term “Coconut”), shaped like a Coconut seed in a way, and some have the most peculiar wings or flanges at the end. Of these three other species, all are easier to grow and faster than P. cocoides. Long term survival has also been better in California. All are from high elevation in the Andes in Bolivia. P. torallyi comes from elevations of up to ten thousand feet and has been reported to be the “highest elevation palm tree in the world”. Cold tolerance of these three later species is excellent, with some surviving into the upper teens F. All have a somewhat silver-green leaf and leaflets. All have a husky trunk. To compare these palms, here’s a synopsis.

Parajubaea torallyi: Tallest of the three, up to fifty feet. Husky trunk averaging 18 inches. Largest seed of the group. Fast growing in the ground.
Parajubaea torallyi variety microcarpa: Smaller than regular torallyi, trunk height to 30 perhaps 40 feet, thinner trunk, smaller seed, equal growth habit
Parajubaea sunkha:  Originally thought to be variety of torallyi, now known to be a species. Smallest of these three species with trunk height 25 feet. In habitat, grows at lower elevation, 6000 feet.
Parajubaea cocoides:  Natural habitat not known, may actually be a variety of P. torallyi, less cold hardy than others above, less silver in the leaves. Not as good a grower as any of the three above.

This is a full sun genus of palms. It is best to start them in strong filtered light. Germination of seeds is difficult. This is the first time I’ve offered this species in years because of the lack of any seeds for years. On the garden photos, the first is from a garden in Encinitas, CA. The second from Balboa Park, San Diego.   The last c/o the European Palm Society in Bolivia.
