Possible re-post. I posted on this yesterday via Gurgle Gropes,, but
it has not appeared there today.

Yesterday I was driven under an arching avenue of Jacaranda trees in
full blossom, an endless corridor of lavender-blue against a dark and
thundery african sky. It was heartbreakingly beautiful, and set me
wondering.

Can I grow the thing in Lincolnshire? Our ever-changing climate is
making me wonder about lemons and peaches, but what about Jacaranda?
