Ceratostigma willmottianum, commonly known as Chinese Plumbago, is a deciduous shrub native to rocky slopes and open woodlands in Central China. It typically grows to about 1 meter in height and width, with a mounding form. The plant is known for its striking pale blue flowers, which resemble those of the true plumbago and appear from late summer to autumn. As the flowers bloom, the leaves begin to turn a vibrant red, adding to the plant’s ornamental appeal. The contrast between the rich blue flowers and red foliage in the fall makes it a standout in the garden.

Chinese Plumbago is valued for its late-season interest and is often used in borders, rock gardens, and as a ground cover. It is relatively low maintenance, requiring only occasional pruning to maintain its shape. This shrub prefers full sun to part shade and thrives in well-drained soils. While it is drought-tolerant once established, it benefits from medium amounts of water during the growing season. It is not commonly afflicted by diseases but can suffer from root rot if planted in poorly drained soils.CC BY-SA 4.0
