Research has found a signal of one more transfer event. This had introduced chloroplasts from an ancestral member of the ''Verbena'' lineage nowadays found in South America into ''Glandularia''. Although all members of the present genus can be distinguished to have a

hybrid ''Glandularia'' are very widespread from northern Central America northwards. The second genetic introgression must have occurred before the genus spread north, as species with the ''Verbena''-like chloroplasts are found all over the Americas. Since the new chloroplast genes replaced the old ones, it may be that the possibly hybridogenic ''G. bipinnatifida'' actually underwent horizontal chloroplast transfer twice in its evolutionary history.

Though tender perennials, they are usually grown in temperate areas as half-hardy annuals (sown under glass), or sold as young plants for planting out after the danger of frost has passed. They are still widely referenced in the British horticulture trade as verbenas. The following have gained the
