On the 11/28/2015 walk at the (Indian River) Lagoon Greenway led by Ken Gonyo, interest abounded in the marvelous mat of sea purslane (Sesuvium portulacastrum). This native plant is related to “commercial” species of purslane with larger, showier flowers that are sold in garden center.

The purplish-pink flowers of sea purslane are smaller than a dime.
