Lovely Yellow Flowers in the Napa Valley

We were in Napa Valley and saw lots of yellow flowers after the rains in late December.
Grape Vines are planted in orderly rows and in between each row are layers of mustard flowers.It's so beautiful.

as soon as it rain , the wild mustard sprouts and before you know it we’ve got a lovely carpet of yellow flowers.

Mostly, we just enjoy the mustard but it does have some benefits. It has a thick, carrot-like root which helps with drainage. And, when you mow it down and turn it under it adds very nice organic matter which improves the soil structure. And there have actually been studies that show that mustard can help control soil pests – nemetodes in particular.

The mustard season is fleeting – usually just from about late December to March, so enjoy the pretty yellow flowers while you can !!
