The state wildflower of Florida, Coreopsis is a great summer bloom. Be sure to choose single-petal varieties, which allow bees to access the flower's pollen.

Recommended Species

In general, when selecting Coreopsis species, choose those with wide, open, single-petal platforms. Cultivars with multiple petals sacrifice pollen for the sake of showy petals and make it more difficult for the bees to access what pollen stores may be available.


Coreopsis lanceolata (lanceleaf tickseed), which is found coast to coast, is routinely available and can be grown in most parts of the U.S. and Canada. It is a vigorous perennial that will grow in most soil types and will attract many of our late summer native bees.


Coreopsis grandiflora (large-flowered tickseed) is found in natural settings along the east and west coasts, and is also distributed throughout the central states, though absent from the Midwest. This species is, however, carried by most nurseries throughout the U.S. and does well in most garden settings.


Coreopsis tinctoria (golden tickseed), an annual species with deep red centers, is native to most regions of the U.S. and Canada. It is routinely available and grows well in most gardens.
