I got some seed when on holiday in Crete, and have finally given
up on it (after about a decade!) It grows and is lovely in flower,
but I have got it to do that ONCE - every other year, aphids stop
the flowers and shoots developing. Perhaps I would have more if
I sprayed heavily with the nastiest sort of persistant insecticide,
but I don't want to do that. Merely spraying to eliminate the
worst of the aphids doesn't help.

Heaven alone knows why. L. x tellmanniana was as bad when it
didn't get significant sun, but it (and this) get a fair amount
of sun - and it is only L. etrusca that is hopeless.
