My Tibouchina semidecandra had been a lot happier this summer than
most, and has really come into its own as the chill has started.
While it is tender, I get the impression that it doesn't like
temperatures of above 15 Celsius. It certainly likes mist, and
gets unhappy in dry conditions.

Will it grow outside (clearly not here), and would keeping it in
a large pot of free-draining J.I. compost help? It is certainly
happy with my mixture.

And, of course, it is spectacular and flowers for ages. But you
knew that!

A friend in Bristol has kept hers out for the last 3 winters, using
fleece in very cold weather. She does have a very sheltered inner
city garden. I shall not risk keeping mine outside, out of the city.
The friend is South African, and says they grew into"trees" in SA and
survived quite low temps.
