I've just come back from my honeymoon and it was excellent! We went on a cruise (with P&O) to the South Pacific. I was quite amazed with the vegetation. In parts, I saw Callistemons, Acacias, She-oaks and a lone Dianella longifolia in the midst of Cocos nucifera (Coconuts), which looked odd. It was also behind a dis-used toilet block which I thought might have something to do with it. There were many plants I know for a fact, as a gardener, we use in our gardens. We pay exhorbandant amount of money to have them in our gardens and they are running havoc over there. Most amusing. Tradescantia pallida is a prime example. People love it over here because its purple. I remember the first time I had anything to do with it and I whooped out loud. A purple plant, how fabulous! Blechnum nodum or annoyingly known as Fish Bone was another such plant that was everywhere in New Caledonia. I hate that thing with a passion. You can't get rid of it. I have a client by the beach and she had it everywhere - as a border - and I've dug it all out. Or so I thought and guess what? Its still coming up.
The following are some of the plants I saw whilst in Vanuatu and New Caledonia.
1. Plumeria rubra 2. Hibiscus 3. Tradescantia spathacea 4.Cocos nucifera
5. Araucaria heterophylla
