I took this before sunrise in my friend Erika's Sacramento Valley garden last week. I'm pretty sure it's a variety of Agapanthus, but I'm going to have to rely on some of you more knowledgeable gardeners out there to help me out. It looks for all the world like Agapanthus africanus 'Dwarf Lily of the Nile', except for the prevalent stamens and the cone-like nature of the still-closed buds in the middle of the umbell. I'll bet Makiko will know. ^^
Ed. note: Makiko did know - The correct name for this flower is Scilla Peruviana. Thanks Makiko!
