Most Baptisia bloom in March, April or early May, but it varies depending on species, region and weather. Bloom typically lasts between 3 and 6 weeks. Flowers are held in impressive upright racemes (flower spikes with a short stem attaching each flower to the main stalk) of blue, white or yellow flowers.

Why is my Baptisia not blooming?

The plant does not bloom well in acidic soils, so adding lime in those conditions can improve flowering. Keep well-watered until established, after which time it is drought tolerant. Overwatering may cause the stems to flop over.

Does Baptisia bloom all summer?

All these baptisia are hardy to zones 4 and can grow well in full to part sun. Although they only bloom in spring, the shrubby, pea-like foliage stays green all summer providing a perfect backdrop to other, lower growing and later blooming perennials.
