To replace a flowering crab, I was thinking of using Bud 9, not as rootstock, but as the tree itself. It has been called red-leafed paradise. What I haven’t been able to find is a description of its blossoms – color and abundance. Fruit is not an issue, but I’ve seen no description of Bud 9’s fruit either. Anyone have answers?

I personally dont find Bud9 root stock all that attractive. Plenty of other red leafed apple trees that make a prettier tree in my opinion. Many of those have showier blossoms as well.
You will have to stake an own-root Bud 9 tree, just as you have to stake a scion variety on Bud 9. That would detract from it for me, for ornamental use.
I staked my one tree on Bud9 with one of those flimsy green plastic coated 8’ stakes when I first planted it. This year the stake was clearly not strong enough, and I had to go back in and put in a t-post. The tree was wobbling around in the wind.
I have a JF Schmidt Royal Raindrops crab. It is a nice crab, but patented, so it is more expensive. Nice tree. If only most of our fruiting apples varieties had its branch structure.
Thanks for the responses. The chief advantage of the Bud9 for me is that I have Bud 9 available due to failed grafts.
