History: The first cross, Dypsis cabadae, was likely the second Dypsis hybrid to be reported in cultivation. A specimen of unknown origin appeared on the Palm and Cycad Societies of Australia website and created some buzz. Since then, this particular hybrid has been successfully grown in California, Hawaii, Florida, and some other tropical countries. It is usually discovered growing among batches of pure Dypsis cabadae at nurseries in Florida and Australia. The second cross, Dypsis pembana, is extremely similar and was first developed by Seabreeze Nurseries in Florida in 2012.
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 Cabada Palm or similar Pemba Palm (Dypsis cabadae: also native to Madagascar but found in tropical rainforest or D. pembana native to nearby Pemba Island) the resulting hybrid seed becomes a White Triangle Hybrid or TriBana Palm. The percentage of viable seeds is fairly low probably due to the fact that both parents do not have similar chromosome counts and one has a clustering habit while one has a solitary habit. Both have ramenta present on and above the crown shaft and neither is in the vonitra complex so alludes to their proposed compatibility.
Benefits: This palm is much more robust than the pure Cabada or Pemba palms. It also features a turquoise trunk with beige rings, a white crown shaft with the signature triangular frond arrangement which is highly ornamental, and a little bit of rusty-red ramenta at the base of the fronds. It is generally faster and more drought-tolerant than either parent, making it a great palm for Tropical, Sub-Tropical, and coastal Mediterranean 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 first couple of leaves of this hybrid are bi-fid and dark green- a trait inherited from its Dypsis decaryi father which generally has thick, leathery leaves compared to other rainforest palms of the same genus.
