The plant's common name is derived from its bright green, succulent leaves (Figure 1), which, when crushed, have a lemony scent. The leaves can also change color, turning red or bronze with increased light intensity,(Figure 2). Lemon bacopa is not very tall (4-6 inches), but its lateral growth is significant. It appears to creep across the surface, sprawling in all directions. Of the species found in Florida, it is the only one to produce blue flowers and these are typically found above water (Figure 2).
Looking for a plant to accent your home aquarium? Lemon bacopa is fairly easy to grow, so give it a shot. Contact the Florida Association of Native Plants to find a vendor near you. After you’ve got one, you can propagate it from the side shoots and share it with a friend!
