It happens every year. As soon as the last garlic cloves are tucked into the ground, I start thinking about how one can never have enough spring-blooming bulbs, so why not plant a few more? As with all decisions about pretty flowers, I keep in mind the permaculture notion that plants should serve multiple purposes. Ring the bells and call the people, because very early bloomers like crocus and scilla provide pollen and nectar for bees on mild late winter days, when little else is in bloom.
