I've grown purslane for many years in various pots & planters around the place because it's such a good hot-weather plant. The house finches are really feasting on them this year & just within the last month. Hardly a bud comes up that a finch doesn't get. They're eating the leaves too but doesn't seem to be enough to hurt the plant. There's just no blooms left anymore. I don't recall them ever making this much of an impact before. Could this be due to the extremely hot weather we've been having? They're also feeding on blackoil seeds & are regulars at the birdbath.
