Hi Roland, I've made it through all 32 pages now.  If you want, I can delete all those guesses, since they were long answered already.  Let me know.
I hope you do LOTS of NAME THAT PLANT.  I would love that game.  That was really fun.  I haven't gardened in a few years, so it draws on recently unused parts of my brain.
What a gorgeous garden, and really good photographs, too.
I had no idea....
No wonder your sig line - I thought you were just referring to Le Petit Prince.  (And do you know the Gil Bécaud song too?)
