The living roof at the California Academy of Sciences in San Francisco's Golden Gate Park is now pretty much grown in. And in the spring sunshine this last weekend it was abuzz with bees and looking quite splendid.
For some reason I was expecting it to consist mostly of succulents, but that's not at all the case. There were some dudleyas but otherwise it was a mass of thrifts, grasses, sages, daisies, and wild strawberries with the occasional California poppy dotted around.
