yes, there are quite a lot of cultivars on my list that have an expected bud count of only 16-20...
That's the only reason why I would allow myself 25 different ones
That, and because I like the way they look on the photo
(I have no chance to see them in real life)
But not re-blooming might be a good point...
High ones would get a place at the back of a border, against a blank wall, so that's no problem
