This Coreopsis is a Florida native and is also called Tickseed. It blooms bright yellow flowers all year long but is considered a short-lived perennial or long-lived annual so it is best to let the plants reseed in order to have continuous coverage. It can tolerate occasional periods of flooding or more damp areas. Coreopsis is the state wildflower.
How to care for Coreopsis
Light. Full sun gives the most flowers.
Water. Keep the soil fairly moist, since it has low drought tolerance. It handles occasionally wet spots.
Soil and feeding. Grows in sand, loam or clay, acidic to slightly alkaline. Well-drained soil that is not too rich keeps plants upright, so go easy on fertilizer.
Size. Grows to about 2 ft, spreading 1–3 ft.
Pruning. Remove spent flowers promptly to extend blooming. Leave some flower heads to set seed for the next generation.
Problems to watch. No serious pests or diseases are known. Plants usually last only 3 to 4 seasons, so let them reseed.
Good to know. A Florida native that attracts butterflies and bees. In South Florida it may keep blooming through winter. Seedlings can come up outside the bed.
