Native Range

Endemic to Florida. Coreopsis leavenworthii is found from north Florida south throughout the Keys.  It is native to Alabama and Florida.

Grows in zones 8 to 11.

Landscape Use

In the home landscape it grows in full sun with average to moist soils. It needs a good source of sunlight in order for it to produce flowers and keep the plants from becoming too leggy.

It does well along the edges of natural areas where it can create a splash of color along the boundary.

The best scenario is to plant it near a water source, or wet problem area such as a drainage ditch, so that it won’t require any watering.

Wildlife Uses

The flowers are a source of nectar for many insects including bees, beetles, butterflies, flies, and wasps.


Can be grown easily from seed, naturally occurring seedlings can be easily transplanted.
