Laguna de Santa Rosa
Chicory is a non-native plant in the Aster Family that has become naturalized and decorates roadsides everywhere. Various varieties are cultivated for salad leaves, chicons (blanched buds), or for roots (var. sativum), which are baked, ground, and used as a coffee substitute and additive. It is also grown as a forage crop for livestock. The Wikipedia entry for Chicory goes into great detail about the interesting uses for this plant.
