Discussion

Lindernia grandiflora has been introduced into the horticultural trade in the southern United States as a container plant or groundcover for wet areas or in bogs or water gardens. It is sometimes sold under the name "Ilysanthes floribunda," which has no standing in botanical nomenclature, or as blue moneywort or angel's tears.
