I've got some geraniums which have been in full leaf for some time (most of the - ahem - summer) but no flowers have come or buds. I seem to remember they did flower last year. Two other varieties (one that was already in the garden, and a new one) have both flowered. I don't know what sort it is as it was something we managed to save in this garden when we bought the house.
Just wondered if anyone else had had this problem this year, in case it was something to do with the weather. The leaves all look perfect so not like something eating it, or mouldy or anything. Quite baffled.
