(Tree Verbena)The genus Aloysia is a verbena relative containing about 35 species of intensely fragrant shrubs from the Southwest US to Chile. Some species (i.e., Aloysia triphylla aka Lemon Verbena) have fragrant leaves (when bruised) but other species, (i.e., Aloysia virgata) have powerfully fragrant flowers. Aloysia flowers attract butterflies. The genus Aloysia got its name the Spanish phrase "Herba Louisa" referring to Princess Louisa, the wife of King Carlos IV of Spain.
Aloysia prefers full sun and well-drained, consistently moist soil, although aloysia does not like to be too wet in the winter. In warm climates, Aloysia are evergreen shrubs, but in our Raleigh, NC garden, they are dieback perennials. Try combining aloysia with other summer perennials such as canna, tamarisk or hibiscus.
