No. But I've grafted tomato to pepper and vice versa. And tomato to tomato.

I'm curious as to why you want to do this?

to have several types of peppers on a single plant

That's why I first grafted tomato to tomato about 10 years ago. Called the plant my "twomato".

which way did u graft it? Did you stick an extra branch on there?

Why not simply have 2 plants????

I must be missing something here.

Yes, grafted a very small branch to a node area on another plant where I removed a branch. Also grafted main stalk of small pepper seedlings to a very vigorous tomato variety that is grown only for root stalk and disease resistance.

Some of us try things that aren't really practical just because we are curious if we can do it.

I never knew you could graft chiles....guess it makes sense though. I have a grapefruit tree that has tangelos on it, and a lemon tree with limes. I call it my "7-Up" tree ;-)

pepper plants have the same vascular system as one another, it would be cool to have multiple types of peppers on one pepper plant
