Coreopsis leavenworthii is a commonly seen wildflower found growing in wet flatwoods, wet pinelands, disturbed sites, roadside ditches and fields.

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. Seedlings and immature plants can be easily transplanted.  Learn to identify it when it’s young and you can place them where you want them.

Since Leavenworth’s tickseed is an annual wildflower you have to be a little more careful about transplanting them.  Make sure to keep as much soil as you can around the roots disturbing them as little as possible.  Usually you can cut out a chunk of soil with the seedling within the clump.  If the area is especially dry then take the time to water for a few days before you try to transplant them and the soil will stay together better. Be sure to cut off any flower stalks as well.  Water until established.
