A few weeks ago I finished reading a book that my friend, Aruna, gave to me sometime last year (possibly even longer ago than that).
The Language of Flowers was purchased at a secondhand bookshop (during a visit to Santa Fe, I think) and, as you can see, Oleander is given the meaning Beware.
I was told several years ago that it is highly toxic, but through online research, found lots of conflicting information on just how poisonous it is. I don't plan on eating any part of it to find out. :) It grows well in our climate and has a lovely, sweet smell.
