Baptisia australis - Blue False Indigo
Best hardy perennial for attracting pollinators to sunny gardens.
Blue False Indigo is a striking wildflower known for its clusters of dark indigo blue flowers that bloom in early summer. Its handsome bluish-green foliage is also attractive and makes for beautiful floral arrangements. This plant is a host for many butterfly species and is also deer resistant. Baptisia australis thrives in full sun to partial shade and is easy to grow from seed, though it develops a deep tap-root that makes transplanting difficult once established. All seeds from Wildflower Farm are hardy through growing zone 3, organic, and non-GMO.

Know before you buy
No, this plant is not suitable for containers. Baptisia australis develops a very deep taproot that requires significant ground space to establish properly.
You can sow these seeds in late fall, winter, or spring. Planting in late fall or winter often helps the seeds undergo the natural cold stratification process that can improve germination rates.
Yes, Blue False Indigo is considered deer resistant. While no plant is entirely immune to hungry wildlife, it is generally avoided by deer compared to other garden favorites.
You can expect this perennial to reach a mature height of 3 to 5 feet. Be sure to account for this height when choosing a location in your garden beds.
