Sub-Tropical Presentation from Gavin

At the January 2016 meeting Gavin gave a presentation of images from his family's recent visit to Hawaii.

Heliconia, and a very nice one too! 

This following image created a lot of comment and discussion from the membership so thought it best to write a little about it.

Rainbow eucalyptus (Eucalyptus deglupta) is the only eucalyptus tree indigenous to the northern hemisphere. It grows in the Philippines, New Guinea and Indonesia where it thrives in tropical forests that get a lot of rain. The tree grows up to a mighty 76 metres tall, so perhaps not one for the suburban backyard. In Hawaii, these trees do so well because of the plentiful rainfall.

It is the multi coloured trunks that show deep red, orange and blue stripes, changing as the bark sheds during the year. Particularly attractive after rain, it does require a frost free environment, however it is now grown as far south as Sydney and could survive further south if the area is frost free. 

The tree has a habit of peeling bark which reveals a white to pale green colour and this then ages to the 'rainbow colour' which is just so popular.Although the tree's colour isn't as intense outside its native range, rainbow eucalyptus bark colour makes it one of the most amazingly colourful trees you can grow.

This gorgeous pink Ginger is Alpinia purpurata.

A beautiful hibiscus. Gavin mentioned that the weather was a bit wet however, the moisture droplets on this flower are just lovely.
