San Diego button celery is an annual herb from the parsley family and is often recognized by its low spreading appearance and greenish flowers. It once occurred in many vernal pool systems, but by the late 1980's 23% of vernal pool systems had been destroyed, leaving remaining populations impoverished.

Vernal pools, one of California's most threatened habitats, are natural depressions that fill with water during the winter and spring and dry up during the summer. Plants that live in the vernal pool ecosystem are specifically adapted to their ephemeral pool environment. The pools are too wet in winter for upland plants and too dry in summer for aquatic plants. Like other vernal pool plant species, Eryngium aristulatum germinates during the flooding period and blooms as the pools dries.
