I have three tickseeds planted an inch apart from each other and they are growing very well with alot of hard rain. they also did well with little water in my garden, although i did not let them get completely dry.

This plant is very showy when in full bloom. Usually the heaviest bloom is in the early spring, but it will continue to bloom. This plant can bloom at any time during the year, but it's not common to see it in bloom in the winter time. C. leavenworthii likes moist soils and well-suited to bogs or water gardens. It is easy to cultivate. This plant is endemic to Florida.
