Black-eyed Susans will grow in almost any soil, as they are native to dry fields where the soil is not rich and fertile. They must have a well-drained soil and a sunny location but will tolerate partial shade. In a partial shade garden, you will have to stake plants, as they will stretch for the sun. The plant will produce fewer flowers in partial shade but is still worth the effort.

Cutting flowers for the house will also stimulate the plant to make more flower buds and continue to flower. Removing some of the mature black cones on the plant will do the same and you can crush up those cones for seeds for your garden. Just sprinkle them on the ground, as it is not necessary to cover the seed. You can plant seeds in the spring or fall but fall-planted seeds have a better chance to flower the following summer. You can also divide the plant in the spring to make several new plants.
