Snowdrops are just my favorites! They are the first bulbs to show up in the middle of winter (thus their name) and they naturalize here very easily.
Lilies of the Valleys don't do well here because it doesn't get cold enough for them, but these are a lovely alternative, although they aren't really fragrant. This little patch in Laguna has been there for eight or nine years at least and they still show up to our delight every year! I always forget to plant more! I must remember next year because I absolutely adore them.
