Mirabilis , a Winter-Spring grower and bloomer.  Usually looks withered/dead during the dry half of the year, or rather is not noticeable, since the stems are rather frail, and don't really hold up during the dry half of the year.  Yellow flower in middle is Calochortus weedii, and the pale pink flower spots amongst the grass and into the Mirabilis are Centaurium venustum, which occurs in both hot pink(most common) and pale pink.  White 'stemmy' plant immediately touching behind the Mirabilis is Euphorbia misera.  The grasses are apparently non-native annuals.  Location: Point Loma.
