To learn a little about palms, I went to palmsonline. On this site is also a Palm Growth Chart, where you can see at a glance some relevant information.
After our experience with overgrown conifers, I am treading carefully in choosing palms, some of which are known to grow to twenty metres.
First thing I checked was suitability for our climate, then the palm’s maximum height. The spread of the tree, rate of growth, whether it drops its fronds, and general attributes. I don’t intend having a huge amount, but enough to make a collection. One random palm does not a tropical garden make.
Chinese windmill palm, Chamaedorea cataractarum, and Cocos palm Sygrus romanzoffiana, with a potential height of 15 metres are perhaps a little tall. In Brisbane I believe, the latter is classified as a weed, due to its rapid growth in a tropical climate, something in Melbourne that is not an issue.
European fan palm, Chamaerops humilis, is a smaller 4 metres by 4 metres with a clumping style.
Foxtail palm, Wodyetia biturcata, is a moderate growing 10 metre palm with a 3 metre spread, fairly hardy variety with a feather type leaf, but can grow to 20 metres in Queensland.
Kentia Palm, Howea forsteriana, indicates 18 metres for outdoors, so definitely not.
Majestic palm, Ravenea rivularis, 12 metres by 4 metres is a possibility.
Wine palm, Butia capitata, a slow grower 5 by 4 metres has potential.
Now it’s raining; just the day I wanted to go shopping with my list, to get some friends for my Pygmy Date Palm or Miniature Date Palm, Phoenix Robelenii, which is not listed on this site, maybe merely meaning they don’t sell it.
