I don't know why this did not occur to me before when we were talking
about LotV, but on my way back from the greenhouse just now I passed a
container that nudged my memory.
While sorting out one of my cold frames a few weeks ago I came across
several small pots of LotV that I had potted up last year but did not
get sold. Not needing any more in the garden, I stuck them all in an
empty container. They are now thriving and just coming on to bloom. Of
course I cannot say yet if they will continue to do well there but I
don't see why not. So if you have a garden that will not accept LotV
why not try them in a container?
