Potted dragonfruit plant.
2nd picture is just an example of a larger specimen and not for sale.
They grow fast and are easy to care for. This one is already rooted and has new growth so it has a head start. If you have it in the sun outside next summer it should grow about one more foot by the end of summer. This one is about 10 inches.
I also have another larger plant that i can sell cuttings off of if you want .
