Coreopsis leavenworthii, commonly known as Leavenworth's Tickseed, is a cheerful, native wildflower essential for any Florida-friendly landscape. It is particularly valued for its ability to thrive in moist conditions where other flowers might struggle.
Plant Profile & Characteristics
- Growth Habit: An upright annual (sometimes short-lived perennial) that grows 18–36 inches tall. It features slender, wiry stems and fine, deeply lobed foliage.
- The Bloom: Bright yellow, daisy-like flowers with a distinct dark brown or burgundy center disk. The petals often have a notched or "pinked" edge, giving them a jagged look.
- Ecological Value: This is a major pollinator plant, attracting a wide variety of butterflies, bees, and beneficial insects. It is also the species of the Florida State Wildflower (collectively with other Coreopsis species).
Growing & Care Essentials
- Sunlight: Performs best in full sun but can handle very light afternoon shade. More sun generally leads to more blooms and sturdier stems.
- Watering: Unlike many other Coreopsis varieties that prefer dry soil, C. leavenworthii loves moisture. It is naturally found in wet prairies and pinelands, making it perfect for rain gardens or low spots in the yard.
- Soil: Tolerates a wide range of soils, including sandy, loamy, or even clay-heavy soils, provided they stay relatively moist.
- Hardiness: Primarily grown in USDA Zones 8–11. It is very heat-tolerant but will die back after a hard frost.
Quick Facts
Bloom Time: Year-round in South Florida; Spring–Fall in North Florida.
Maintenance: Low; deadheading encourages more blooms but isn't strictly necessary
Self-Seeding: Strong; it will readily drop seeds to create a new colony next season.
Salt Tolerance: Moderate; can handle some coastal influence but not direct salt spray
