Are both Nigella and Leucanthemella both plants?
Leucanthemella Leucanthemella is a genus of flowering plants in chamomile tribe within the sunflower family.
Lippia Lippia is a genus of flowering plants in the verbena family, Verbenaceae. It was named after Augustus Lippi, (1678-1705), a French naturalist and botanist (with Italian origins). He was killed in Abyssinia. The genus contains roughly 200 species of tropical shrubs that are found around the world. Plants are fragrant due to their essential oils, which vary between species but may include estragole, carvacrol, linalool, or limonene. The leaves of certain species, such as "L. graveolens", can be used as a culinary herb similar to oregano.
