Coreopsis
Tickseed
is the common name for the plant Coreopsis, a group of 35
species of flowering plants in the Family Asteraceae and Genus
Coreopsis. Twenty-eight species are native to North America and
the others come from Central and South America. The flowers are
usually yellow with a toothed tip. The name is derived from the
Greek word koris, meaning Bug. The plants are also popularly
called "Calliopsis." This genus is primarily native to North
America. Many cultivars are available for gardens. Coreopsis
species are used as food plants by the larvae of some Lepidoptera
species including Coleophora acamtopappi. Since it can
tolerate soil of low fertility and withstand intense heat,
coreopsis will succeed in urban environments and in roof gardens.
Tickseed is also able to tolerate salt and wind in a seaside
garden. Does not usually live more than two to three years unless
clumps are divided.
