The image of the Begonia "exotica" was implanted in my memory 10 plus years ago while reading Alfred B. Graf's book "Tropica" borrowed from library. In fact, I probably borrowed the book more than ten times - it was a stress reliever and I literally hugged the heavy book to sleep. Anyway, this strange new species tentatively named Begonia "exotica" from the mysterious island of New Guinea, was so different from any Begonias I knew, psychedelically coloured leaves and all, that I set my sight to hunt it down at all cost, even to the dark depths of New Guinea ...
Luckily, I did not have to go that far. When I eventually saw it on the rack of a private collector a few years later, my heart was thumping.
I remembered he said, almost apologetically, that it would be a bit expensive as it was a rare plant
So how much ? I asked
8 dollars, he replied.
I grabbed it immediately and thanked him profusely. Nowadays, you can probably see them on sale in quite a few on-line sites but in those days it was indeed rare.
As it turned out, what I had was not exactly "exotica" but the subspecies Begonia brevirimosa brevirimosa (by the way, subspecies is a taxonomic term meaning naturally occuring variants of ths same species). In 2005, Mark Tebbitt formally described "exotica" to be a subspecies, rather than another new species, after considering the flowers and fruits characteristics. I acquired the real "exotica" only last year and finally had a chance to compare the two. Both of them are quite similar but not really the same - the dominating bright pink streaks for "exotica" really stood out.
Given some shade from full sun, warmth and high humidity, the plants thrived at my plot - but do not seem to flower freely. Unfortunately, snails and slugs cannot leave them alone and they cannot adapt to the drier balcony environment when I tried to bring them indoors.
