Baptisia 'Australis' is a robust long lived perennial known for its striking spires of indigo blue flowers and attractive blue green foliage that forms a dense shrub like mound. After flowering it produces ornamental black seed pods that persist into winter, adding structural interest and visual contrast. The plant is prized for its longevity, clump forming habit, and ability to enhance early season pollinator activity in native plantings and mixed borders.

WILDLIFE & INSECTS
Butterflies
- Provides nectar for butterflies such as Eastern Tiger Swallowtail and Silver Spotted Skipper during its spring bloom period.
Bees
- Attracts long tongued native bees including bumblebees and carpenter bees that are drawn to its deep pea like flowers.
Moths
- Supports the Wild Indigo Duskywing and other Lepidoptera species whose larvae feed on Baptisia foliage.
Birds
- Songbirds such as goldfinches and sparrows may forage the seeds from its dark pods and use the sturdy clumps for cover.
Spacing & Landscape Use
Spacing Recommendations
- Space 36 - 48 in apart to accommodate its mature size and upright branching habit.
Landscape Placement
- Excellent as a specimen plant, mid border anchor, or structural component in meadow and prairie inspired designs. Works well in large pollinator beds and resilient native plant landscapes.
Companion Plants
- Coreopsis verticillata 'Zagreb' (Threadleaf Coreopsis) - Compact yellow bloomer that offers vibrant contrast to Baptisia's blue spikes and fine textured foliage.
- Monarda fistulosa (Wild Bergamot) - A native aromatic perennial with lavender flowers that attract pollinators and complement Baptisia’s cool tones.
- Asclepias tuberosa (Butterfly Weed) - A bold orange native milkweed that thrives in similar dry soil and attracts butterflies and bees alike.
- Symphyotrichum oblongifolium (Aromatic Aster) - Fall blooming aster that adds late season color and pollinator support in prairie mixes.
- Echinacea purpurea (Purple Coneflower) - Sturdy native perennial with large central cones that harmonize with Baptisia’s upright form and feed finches in fall.
