it's not prolific - but I think I counted 15 buds. - the one in the garden has five flowers
- the other on the patio has about seven buds [actually can't remember what I counted]
- this is nasty quality - but for a while my phone was refusing to meter this at all, so beggars can't be choosers
PS today I learned that what I think is a hydrangea is actually a guelder rose [which looks absolutely nothing like a rose in any way, shape or form] - and I think I might remember!
