I planted these Veitchia joannis as small 4" pots last year and they are rockets in our cool montane tropical conditions growing next to our coast redwood trees.

    They are a nice palm the joannis. And will take temperatures down to 0 degrees celcius, not that you will see those temps in sunny Hawaii.

    I wonder why these are not more common in places like California and the mild parts of Europe. Our lowest temperature here is around 48 to 52. So no chance of testing its hardiness, but it does not seem to need a lot of heat.

    They're probably about 3-5 degrees more sensitive to cold than arecina. So definitely a collectors palm around here. That said, pending an unusual freeze, they do pretty well. Definitely not like trying to grow Carpoxylon or Cocos.

    The tree in my home town of Grafton even sets seeds that are viable from a single tree. Don’t underestimate the joannis, even possibly minus 2 temps have been recorded now and then. Where there is white frost patches in low lying areas. And I do remember the morning of the black frost that gave the town a flogging of col, killing the local sugar cane fields. The palm lived.

    That’s about two years growth down here on the coast.
