Acacias and Baobabs
I pointed out to the little prince that baobabs were not little bushes, but, on the contrary, trees as big as castles; and that even if he took a whole herd of elephants away with him, the herd would not eat up one single baobab.
Now there were some terrible seeds on the planet that was the home of the little prince; and these were the seeds of the baobab. The soil of that planet was infested with them. A baobab is something you will never, never be able to get rid of if you attend to it too late. It spreads over the entire planet. It bores clear through it with its roots. And if the planet is too small, and the baobabs are too many, they split it in pieces . . .
