How much sun does Campanula persicifolia need?
I have two of these in large pots that urgently need dividing. Currently in a sunny spot by the house and this year didn't flower as too congested!
So I'm going to divide them (in London and it's still sheltered and warmish) but Ive nowhere to put extra plants except borders. However because of trees both east and west only get part sun (I'm south east facing). I could put them nearish the front but one gets bits of morning sun but quite full on afternoon sun at the front but only for a few hours. The east facing one gets morning sun but not for that long. Maybe 4 hours?
Or should I just divide them up, put them in different places and see what happens?
I've got the same problem with geums. I love them but as sun varies so much through the year it's difficult to find a reliable sunny spot.
