History: This was the first of the Dypsis hybrids to be reported in cultivation. They were sold in rare plant markets in Australia and made it onto the internet in the early 2000’s. Since then, this particular hybrid has been discovered growing among batches of pure Dypsis leptocheilos at some nurseries in Florida. It has also been manually created by Seabreeze Nurseries in Florida and Nong Nooch Tropical Bontanical garden in Thailand.
Production: By applying the donor pollen from a Triangle Palm (Dypsis decaryi), a palm native to dry lowland forests in Madagascar, to the female flowers on a Teddy Bear Palm (Dypsis leptocheilos), also native to Madagascar but found in sub-tropical rainforest, the resulting hybrid seed germinates rapidly and becomes a Red Triangle Hybrid, aka TriBear Palm, aka Teddy Bear Triangle Hybrid. The percentage of viable seeds is very high because both parent plants have similar chromosome counts and similar morphology. Both have ramenta present on and above the crown shaft and neither is in the vonitra complex.
Benefits: This palm combines the vibrant white, red, and green colors of the ornamental Teddy Bear Palm with the sun and drought-tolerance of the Triangle Palm, making it a great palm for Sub-Tropical, Mediterranean, and mild Desert climates. This hybrid is also sterile- meaning it does not produce viable seed- which can be of benefit in a landscaping application because it will not foster a colony of unwanted seedlings at the base of the tree which often have to be sprayed or removed.
Identification: The Dypsis leptocheilos mother plant produces pinnate eophylls (feather-leafed first leaves) when the pure seed is germinated. When hybridized, the Dypsis leptocheilos mother plant will instead produce seedlings with a bi-fid eophyll (first leaf forked in two), which it inherits from its Dypsis decaryi father. The first few leaves are very dark green and sometimes open red like some New Caledonian palms (this goes away with age).
