Thanks GreatTeacher. I love flowers too, particularly growing them from seed. So magical watching seedlings pop up then later flower. My hydrangeas are really slow too but the Viburnums I bought in March are flowering, so exciting. Will try and post pictures but I find it it very slow posting photos on here from my iPad. Sometimes I leave it going round and round but come back hours later and it's posted.
Edit - worked ok this time!
