Common Name: TriBana Palm; White Triangle Palm

Sun: Full Sun to Shade

Growth Rate: Slow to Moderate when young, Fast once trunking

Fertilizer: None

Water: Very Low

Cold Tolerance: unknown, probably 24-28degF

History: This hybrid was first produced by Seabreeze Nurseries in South Florida in 2013.  It has been distributed to California and Australia.

Production: The seed parent is Dypsis pembana (Pemba Palm) and the pollen parent is Dypsis decaryi (Triangle Palm).  Production numbers are: out of 15,000 female flowers (three inflorescences carry 15,000 pistillate [female] flowers, once pollinated these flowers yield about 50 seeds, out of these seeds about 10-12 germinate and grow to healthy seedlings.  Often, 10% of the seedlings come up as true Dypsis pembana (see Identification below).

Benefits: This hybrid should be able to take a few more degrees of cold than the pure  Dypsis pembana.  As a young palm, the hybrid is slightly slower growing than pure Dypsis pembana, but speeds up quite a bit when older, the fronds are a bit more silver and upright, and also seem more resistant to spotting and yellowing than the pure mother plant.  Also, the hybrid tends to split a couple times, producing two or more trunks, whereas the pure species produces new young stolons (stems) from the base.  This hybrid is a pretty palm with a tristichous (vertical rows of three) leaf arrangement, elongated crown shaft, and an emerald-green trunk that is reminiscent of bamboo.

Identification: Prophyll (first spike/tube) is typically very short- about ¼” or so and colored differently than the eophyll (first leaf).  Eophyll is dark, emerald green and very stiff and upright (unlike pure palm which is lime-green and rabbit-eared).  Hybrid seedlings are also noticeably slower growing than pure Dypsis pembana.
