oh yes lizards tail and Yerba are different all together...yerba mensa is an medicinal herb that grows well in boggy conditions...so it does well with wet feet/dry ankles...dirt is fine to plant them in also can use cheap kitty litter or pebbles....it will get it's nutrients from the water...Lizards tail can take a few inches of water over the roots and it can be grown in the same kind of medium as the Yerba Mensa....Yerba tends to be a bit picky at first but, once it gets established it does quite well...
