Ranunculus white is a rewarding summer flower. The creamy white flowerheads with a green centre are real eye-catchers in borders, gardens, or in pots on a patio or balcony, or as a cut flower. Ranunculus can be planted in the autumn and flowers best in full sun and combines well with perennials and other flower bulbs. Ranunculus are so-called dormant bulbs. They must soak in a bowl of water for a few hours before planting.
