The plant can grow in various soil types, including sandy, loamy, and clay soils. Gardeners should ensure that the soil is fertile and rich in nutrients for optimal growth.
Cultivation Methods:
Baptisia ×bicolor is best grown in medium moisture, well-drained loams in full sun to light shade. It tolerates a wide range of soils. Plants prefer cool, moist summers and dislike hot, dry conditions. However, once established, plants are generally drought tolerant. Baptisia is a slow-to-mature plant but has a long lifespan and is good for perennial borders, naturalized areas, and native plant gardens.
Watering Needs:
This plant is drought-tolerant, but when rainfall is less than 1 inch per week, they need to be watered deeply at the base of the plants. It is best to avoid overhead watering as it can increase the risk of plant diseases.
Fertilization:
Baptisia ×bicolor Greenm. & Larisey does not require regular fertilization. Too much nitrogen will result in lush growth, but will dramatically reduce flowering. However, during the initial planting, the soil can be amended with compost or well-aged manure and a balanced fertilizer can be applied, which will provide slow-release nutrients throughout the growing season.
Pruning:
Baptisia ×bicolor is a low-maintenance plant that does not require regular pruning. Each spring, however, it benefits from a light prune, removing dead or damaged stems to allow new growth for the season. After blooming, it is also useful to deadhead the spent flowers to promote additional foliage growth. The plant should be cut down to the ground in late fall or early spring.
Propagation of Baptisia ×bicolor Greenm. & Larisey
Baptisia ×bicolor Greenm. & Larisey is a deciduous perennial plant with an upright growth habit. The plant can be propagated using several methods.
Seed Propagation
Seeds should be sown in fall or early spring. To improve germination rates, seeds can be scarified (nick or file the seed coat) and then soaked in water for 24 hours. After soaking, the seeds should be planted in a well-draining soil mix and kept moist. Germination can take up to 4 weeks.
Division Propagation
Dividing the plant is a straightforward method of propagation. In early spring, the clump can be lifted and divided into sections using a spade or knife, making sure each section has at least one stem and a good root system. The divided sections should be replanted immediately in their new locations.
Cuttings Propagation
Baptisia ×bicolor Greenm. & Larisey can also be propagated using softwood cuttings taken in summer. Cut a 4- to 5-inch section from the tip of a stem, making the cut just below a leaf node. Remove the lower leaves and stick the cutting in a well-draining soil mix. Water regularly and keep the cutting in a shaded area. Roots should form in 3 to 4 weeks, and the new plant can be transplanted in fall or the following spring.

Using a fungicide treatment can also be effective in controlling Fusarium wilt.
Preventing bacterial leaf spot requires good sanitation practices like removing infected leaves as soon as possible and disposing of them properly. Keeping the plant dry can also be effective in preventing the disease from spreading, and using copper-based fungicides can help reduce the severity of an infection.
Common Pests
Like most plants, Baptisia ×bicolor Greenm. & Larisey can be vulnerable to pests, including aphids, spider mites, and thrips. These pests can damage the leaves and stems of the plant, causing stunted growth, wilting, and reduced productivity.
