No way is Trachycarpus martianus nearly as cold hardy as a Washingtonia... mine was defoliated completely this winter, and my neighbor's Washingtonias has no damage at all.  Rhapis humilis is probably less cold hardy, too, but not sure about that.  I seriously doubt Hyphaene petersiana is more cold hardy, either, but no personal experience with that one... the other Hyphaenes sure aren't.  To me, this is a very narrow zone, as I rarely see damage on Washingtonias without similar damage to P canariensis... I personally would rate them equal, with most of the plants listed here as being less hardy than either.

Seems odd to include Juania in a subtropical list as I know of no subtropical climate in which this species can be grown.. do you?[[User:Palmbob|Palmbob]] 16:53, 22 July 2007 (PDT)

Ranking is from more hardy to less hardy.
If a Washingtonia robusta is hardy in your area, so is everything else on this page.

  • Phoenix canariensis (20.8/-6.3)
  • Sabal causiarum (20.9/-6.2)
  • Dypsis decipiens (21/-6.1)
  • Hyphaene petersiana (21/-6.1)
  • Rhapis excelsa (21.2/-6)
  • Rhapis humilis (21.3/-6)
  • Guihaia argyrata (21.7/-5.7)
  • Trachycarpus martiannus (21.6/-5.8)
  • Livistona australis (22/-5.6)
  • Butia paraguayensis
  • Washingtonia robusta (22/-5.6)
