Got Scurvy?

This plant was everywhere along the coast of California. It's called an ice plant and was planted along Californian highways to avert erosion. According to Wikipedia it's extremely pervasive and it's now a bit of a problem. It looks rather alien and the big mats of it make it seem like it's invading. Maybe it is? Anyway I loved the vivid colors, in particular the buds that were turning yellow and red. Our seal guide, Ed, told us that sailors, in a pinch, would eat them to avoid scurvy.
