How to Grow White Wild Indigo in Your Garden

If you’re interested in growing white wild indigo in your garden, you’ll find that it is a relatively low-maintenance plant once established. Here’s a step-by-step guide to help you get started:

a. Choosing the Right Location

White wild indigo prefers full sun but can tolerate partial shade. It thrives in well-drained soils and is drought-tolerant once established, making it an excellent choice for xeriscaping or areas with poor soil conditions.
