Baptisia - Blue False Indigo

Baptisia australis
Native to the eastern half of the country and once known as Blue Sophora, by 1758, false indigo was comfortably settled in gardens. The pinnate leaves are blue-gray and look great all season long, and the dark lavender blue spires of pea-like flowers add much to the overall lushness of the June garden. Low maintenance and long-lived, it becomes a small bush in time and a classic companion to peonies and roses.

PLACEMENT & CULTIVATION
False Indigo is native to North America and attracts butterflies and bees. Since it is somewhat toxic, it is also deer and rabbit resistant, making it an excellent selection for naturalized borders, cottage gardens, or even more refined, formal settings. Shear by 1/3 after bloom to regrow bushy foliage for the rest of the season, or keep full size to enjoy the large seed pods. Caution: all parts contain some toxic elements.
Final Spacing:
1.5-2.5'
Water Requirements:
Medium Water Use
Watering Details:
Baptisias develop deep taproots and once fully established in 2-3 years, little additional water is needed.
Soil pH:
Prefers slightly acidic pH levels. Do not apply lime.
Fertilizer:
While Baptisia does well even in soils lacking fertility, it is helpful to provide an organic balanced fertilizer or a layer of compost in early spring
Diseases & Pests:
No major pests or diseases. If insect or fungal problems arise, treat with neem once per week until the problem is resolved.
When to Cut for Bouquets:
Harvest when florets are 1/3 open.
