I got it from Kobakoba who got it from Crug Farm Plants (BSWJ 312b).
It is large growing and quite vigorous, producing these jolly flowers in September. My plant
is entirely green leaved, but I have seen photographs of a spotted form.
When I first got it, I thought it would be a rather delicate grower, but it has turned into a muscular thug, which is very gratifying.
