That's not definitive, Eric. We will only know by DNA analysis and/or, when someone manages to get viable seed from a selfing...and grows them up and blooms multiple clones. If there is much variation...it's likely a hybrid. If the flowers are all very similar, it's likely a species.
Whatever it is, it's hard to come by; which hopefully is a situation that will improve. It's a wondeful plant. It's vigorous and it readily produces side branches. It also frequently holds multiple flowers on the same growing point. So, a strong plant with a single stem with 2 side branches can have up to 9 flowers open at the same time! :clap:
