>> sometimes you see lots of berries & sometimes not.
I have one very tall shrub that I keep pruning back: some years it has tons of red or red-orange berries and some years few. I never thoguht it might be a holly. I'll take a picture and ask for an ID.
If she is Holly, I wonder what neighbor, how far away, has a male Holly? Not me!
But I do have a tiny plant that has leaves that I think shout "Holly" and it might be male. I only noticed it 3 years ago, and it might be 16-18" tall now. It's growing on a slope of thick, solid, dense clay. I'll be loosening the soil around and below it to improve drainage.
Does anyone know how old or how tall a male Holly has to be before it can produce pollen? I've never seen anything that looks like a bloom on this little guy - just gloassy leaves with thorns on the tips.
