Luminous, upward-facing chalices glow in the spring garden. Tough and easy, California Bluebells, also called desert bluebells, laugh off the most inhospitable conditions like cold weather and drought. For the greatest impact, sow this heirloom in large numbers. Grow in spaces between paving stones, in rock gardens, and in the front of flower beds. Sow narrow strips of bluebells and violas between vegetable rows! These beautiful, little flowers will charm you, and are loved by native bees.
