Now is my favorite time of year in one of my favorite places in the city: Spring in Crissy Field. To be clear, though, not the grassy part of Crissy. That’s boring. Give me the living, blooming sand dunes any day. But especially in the spring. The Silver Lupins (in the Fabaceae – or pea – family) are exploding purple. White Crowned Sparrows flit in and out of Lizard Tail. While Coyote Bush finally has shed its fur, the irises are just starting to poke out. And Beach Strawberries are everywhere in flower. To this New England native, these are the surest signs of San Francisco spring I have found.
