RE: Eucalyptus calophylla

E. callophylla is the classic Gumnut tree
the large nuts are very distintive 
(and lethal if you ride a bike through them)
They form a globe up to two inches across then just as they 
are about to close up flair out again 

Big trees drop hundreds every year and and the bigger trees overhanging the
roads
litter the ground with nuts causing me some worries when riding past.

Colour is very variable with E. ficifolia from creams and almost whites to
reds and the most 
ghastly 1970's orange... erk!   I know there has been a lot of research
looking at tissue culturing the red forms as these are quite rightly the
most popular.  Some nurseries will hold back on selling the plants untill
they set a few flowers, the reds are dearer obviously,  but heh I'd pay
