Feijoa sellowiana, pineapple guava. Thought of as a tropical plant, but we get a large crop of guavas every year in Shingle Springs. The flower petals are also edible.
Escallonia spp, redclaw. White, red or pink-flowered shrubs are available.
Callistemon citrinus, red bottlebrush. Hummingbirds love these flowers, bees too.
