Does anyone know of this type of small (Korean origin) tree flowering
out-of-doors in England ?
If so, at what age does it start to show flowers in our summertime ?

It seems to be quite tricky to get success with.
The tree doesn't seem to mind cold and damp winters in the garden, but is
very reluctant to grow any leaves at all until daily temperature is peaking
well above 20C ( ie very late May or June ).

A greenhouse environment may also be unsuited as peak daily temperature over
40C seem to cause rapid death to most of the above ground growth.

There seem to be many of these trees available in local garden centres (
typically at 5 - 10 feet high, in pots ) ~ so presumably someone somewhere
is having success with them in England ?
