Caulerpa ashmeadii

[Wasabiroot]

Picked these up from Gulf Coast Ecosystems. They didn't do much at first but have shown some new rhizomatous growth.

Gorgeous specimen! How long and wide are the blades?

Currently they're pretty small. This was a closeup. I'd say 4-5 inches long and about 1.5 inches across.
