sure you can .
variegated escalate not that rare? 2023 , what a time to be alive.
I tried to graft a super rare plinia I can't say the name of for now, but then it didn't make it
...
I did successfully graft variegated scarlet, but I mean, it's not that rare. I think it's a clutch graft cause I had to give away the plant for graftatree so before I sent it off I took a scion...I regret that but at least I have it 
New variety name...can't let them know yet

The plant matrix won't let me.
I hope to post it soon though when I'm not too busy with school and work.
Hint - the name is after another tree with long leaves.
The variegated scarlet is still rare, but at least a few collectors made it more common after a few large trees made it in. LOL
I think the variegated coronata is more rare...and btw if anyone is looking for a plant, I do have one spare.
