Everything that I've read about Itohs says they're sterile but who knows? The corals seem to multiply pretty rapidly so it'd be an easy thing to trade for, Kayleigh. I'm pretty sure I saw one of the corals advertised in Gilbert Wild's spring 2016 catalog as well, their prices are great. I don't think all of the offerings are up there yet so I'm waiting a while to put in an order.
It's funny, I've had Bartzella for several years but have not had a single bloom, nor has the root increased. I decided last fall to move it to an area that I've had better success with Itohs, hopefully I'll see some growth next spring! Also ordered another one from Solaris Farms for next fall, just in case the teeny roots I got before aren't really Bartzella....
