Can anyone advise me of best garden to visit on
(a) Kauai and (b) Hawaii?

Can't give you any advice on gardens but when I
make it to Kauai within the next year or so, I'm
going to be checking out the protea farms. They
should be easy to find.

As far as plumeria on Oahu, hmmmm.........There's
a garden very close to Waikiki very close to the
zoo but I can't think of the name of it. Also,
check out Senator Fong's gardens on the windward
side of the island.
