My Spring BarometerMy Spring Barometer

Daffodils (Narcissus sp.) are classics of spring but not so common outdoors in San Diego gardens because of our warmer climate.  Many years ago, I planted the bulb from a (supermarket) potted gift bouquet into my garden.  Each year if it flowers (like this year) I know it has been cooler and wetter than normal.  Most years only the leaves emerge without a flower.
