Given that this is short-lived (biennial) and difficult to transplant or grow from seed, this is perhaps best encouraged in places where it grows naturally. Minimizing competition from other plants, and perhaps burning the garden area, may be useful. This plant appears to have a seedbank with seeds that may sprout over an extended period of years if conditions are right.
The range of this plant in Florida appears to be disjunct though how much of this is due to site conditions and how much could be an artifact of forestry practices is unknown.
