This large native perennial, known for its profuse purple-blue spikes of pea-shaped flowers, is commonly referred to as False Indigo. In spring, False Indigo produces foot-long spikes of nearly blue flowers that are followed by seed pods. These pods turn black and can be used effectively in flower arrangements. The plant’s leaves range from green to dusty blue, and it typically grows into a full and bushy form.

False Indigo can reach a height and width of around 3 to 4 feet, making it ideal for placement at the back of borders. While it prefers full sun, it can tolerate light shade, though this may result in fewer blooms and a tendency to flop. The plant thrives in alkaline conditions, making it well-suited to the native soils of Kansas. With its deep taproot, False Indigo is challenging to transplant but becomes drought-tolerant once established.

This perennial has few pests or diseases and is relatively resistant to deer. Due to its size, False Indigo works best as an accent plant or in small groups at the back of perennial borders. It is also well-suited for naturalized and prairie gardens, where it can enhance the landscape with its vibrant spikes and resilient nature.
