Our mystery seeds last week were from the common annual flower, yellow cosmos (Cosmos sulphureus).
The flowers of this species are yellow to deep orange in color.
Yellow cosmos supply nectar to pollinators and are sometimes listed as good plants for butterfly gardens.
Because they tend to reseed prolifically, however, they have been listed as invasive weeds in the southeastern United States.
With plants, it is all about location, location, location.
