I'm by no means an expert... but I believe there are generally 2 types of ricordea: Ricordea Floridia and Ricordea Yuma. The former hails from the carribean and is generally more colorful than the yuma which come from the pacific.
Yep, its a west coast east coast thing. Yuma is typically larger and typically can have a wider assortment of colors. Floridia has the beautiful orange ricordia which is becoming harder and harder to find.
I have both and in my experience and from what I have read from others Fla Ricordea is easy to keep but Yumas especially the "rare" pinks and reds can be more difficult to keep happy.
