California Poppies

California Poppy is a pretty native wildflower. It is very drought-tolerant and is excellent for xeriscapes. When the plant stops looking pretty, pull it up/break-it-off. The poppy seeds disperse widely so you will be surprised by the next year’s plants. I always have it in my Sunnyvale garden.
