The Triangle Palm, or Dypsis decaryi, is an eye-catching specimen with a tropical appearance. This ornamental palm holds a certain mystique that is difficult to fully discern at first glance. With closer examination, it becomes apparent that the leaves emanate from three fixed points in a meticulous, wonderful triangular pattern. An uncommon sight in Southern California, the Triangle palm is a head turning specimen and a stunning centerpiece for any landscape project.
A native to a small area of Southern Madagascar, the Triangle palm thrives in moderate climates and on the coast. In fact, examples of this tree can be found on the Southern California coast within feet of the water, and seem to enjoy the the cool, salty coastal breeze.
Although young Triangle palms will not appreciate the full sun and heat of California's inland areas, we do have many dozens of specimens in Riverside growing in shaded areas, with large trunks and a hearty robust appearance. In maturity, these palms will better tolerate the inland summer heat, provided they have adequate water and a bit of shade.
That said, some tinkering is need to keep these the Triangle palm shielded from the extreme heat of the inland and desert areas. Younger specimens will not survive when planted in the full desert sun or in winter freezes, and most of the 100 or so older palms at our Riverside property now remain in partial shade, long overdue for a home near the beach!
