It's a true dwarf Syngonium Lynn and Holly. It's called 'Mini Pixie' and only one of my top ten favorite tiny plants on the planet. They are so durable and tiny with no leave ever getting past 1 inch! They grow in small mounds at maturity and only to 3 or 4 inches high and wide. Love them.
any well drained mix works and I always add Pine Bark fines to all my soil mixes which they love.
I wrote a little about them here:
