That is an interesting question. Are you asking because of the leaf color?

Good question, I bought one off eBay that was labeled a "Concinna," but when I got it home and researched it, it turned out to be a "Subspicata"... maybe they are one and the same? here's a pic of it from last year.

very nice plant!

Yours is definitely subspicata. Concinna has many forms, but all of them spoon leafed.

Vitorama, I was retagging and verifying names and one of the descriptions (internet of course) came up as S. Subspicata var concinna and I wanted to verify.
