Is there a source for seeds for blood oranges, or are they the product of a
graft, and therefore only available as plants?

Just curious, because I had my first experience with them and now am ruined
for "regular" orange juice for the rest of my life! :-)

I am moving to ten acres in a couple of months. Among the many other trees
I want to plant, I would like to plant a small orchard (ten or so) of blood
oranges, but at $30+ per plant, am wondering if there is a less expensive
way to go.

TIA,
