- As a resident of a place that has been almost completely overrun by
- exotics - Hawaii - I say No! It is not ethical. People here plant
- lantana (from Malaysia?), maleleuca (= paperbark, from Australia), kiawe
- (= mesquite = thorn tree, from Africa), and a whole abundance of other
- Gondwana flora such as gum trees. These things are taking over. No
- plant you might associate with Hawaii - hibiscus, ginger, orchids,
- shower trees - got here naturally, with the sole exception of the
- coconut. The local plants - giant thornless raspberries, sandalwood,
- and a zillion others whose names you'd never recognise - are all
- receding before the more robust intruders and many are extinct. Stay
- at a bed and breakfast on the cool slopes of Haleakala and the oaks and
- irises and laburnum will have you swearing you are in England:
- delightful, but completely out of place. The same thing is happening
- everywhere. We are condemning the world to a stultifying homogeneity.
- Afghan pines are taking over the desert southwest of the US (and being
- plugged by that idiot organization Global Releaf), water hyacinth clogs
- streams in the southeastern US, eucalypts march up hillsides in
- California, the list is endless.
-
- Years ago there was an organization in England trying to get azaleas
- and rhododendrons banned because they were "not British." Some of the
- more militant actually tried to saw down some rhododendrons or spray
- them with defoliants (which is appropriate: rhododendron leaves are
- packed with toxins which poison the ground for other plants; did you
- ever wonder why there is no ground cover in the Rhododendron Dell at
- Kew?). I used to think those people were a bunch of whackos. Now I'd
- like their address (if they still exist), as I'd like to sign up and
- start an overseas branch.

- Bravo. Would that more gardeners were so sensible.
