Other info. - This brilliant little plant can be found mainly in the southwest 1/4 of Missouri but is scattered in a few more southern counties also. The plant is an annual but is quite prolific under the right conditions. It likes full hot sun and well drained soils.
S. pulchellum produces much seed and grows easily from seed so it would make a great garden subject. Why isn't everyone growing this plant?
