I really wasn't sure I was going to be able to do it today - gusty winds aren't conducive, however ... the wind dropped and I did a bit of gardening - and then I went round with my secateurs. I was surprised how many I'd got - didn't get one from every hydrangea, nor every fuchsia, and didn't get the only sunflower, but there are 40 (tbc) here.
@chrisiow like I say, I was surprised - but on the way out tonight I saw two more in neighbours' gardens - and that was without trying, so it could be a much greater number! Are you going for it?
