The hibernating vineyards are worth of visiting by the end of winter when its beds are densely covered with mustard blooms. The flowers resemble a blanket that warms up bare vines with yellow, orange and golden colors. It is not clear whether these plantations have wild origins or maybe they were planted by some thoughtful vineyard managers. Anyway, there is a legend which says that those were Christian missioners who brought the mustard seed to California. According to the narration, they were carrying bags full of the seeds on their backs, and the seeds were scattering upon the ground through the holes made in the sacks.
