Bacopa caroliniana has been around in the hobby for many years. Its origins lie in the southeast of the USA, where it is found in marshes, submersed as well as emersed. Several forms of this species are in cultivation, among others a smaller-leaved form and a variegated form. The latter is not too different from the standard form, though. One of the most striking characteristics of this plant is the lemon scent the leaves emit when crushed. The basis of the ovate leaves encloses the stem entirely.
