Leavenworth's Tickseed Coreopsis, Southeastern Native

Leavenworth’s Tickseed is a proud native of the Southeastern United States, specifically Florida, where it is almost entirely endemic. It is named in honor of Melines Conklin Leavenworth (1796–1862), a prominent 19th-century botanist and army surgeon who spent his life documenting the unique flora of the American South.

Historically, the Coreopsis genus has such deep roots in the region that it was designated as the Official State Wildflower of Florida. While other tickseeds are found across the continent, the Leavenworth variety is special for its adaptation to the humid, subtropical environments of the coastal plains. It represents the resilient beauty of the pine flatwoods and wet prairies, standing as a symbol of the untamed Southern wilderness.

Leavenworth’s Tickseed is widely considered one of the most important plants for supporting biodiversity in the garden. Because of its long bloom cycle, it provides a consistent and reliable food source when other plants may be dormant.

• Native Bee Magnet: It is a primary pollen source for specialized native bees, particularly Leafcutter bees and Sweat bees, who rely on the flat, open faces of the flowers for easy landing.
• Butterfly Hotspot: A favorite nectar station for Monarchs, Queens, and Zebra Longwings. Its bright yellow hue acts as a visual beacon, drawing butterflies from great distances.
• Songbird Banquet: Once the flowers fade, the small, "tick-like" seeds provide a high-energy snack for small granivorous birds like finches and sparrows.
• Beneficial Insects: Attracts syrphid flies and predatory wasps that help naturally control garden pests like aphids.

• Prolific Bloomer: Capable of blooming year-round in frost-free climates and throughout the entire summer and autumn in cooler regions.
• Moisture Tolerant: Unlike many wildflowers that demand dry soil, Leavenworth’s can handle "wet feet" and is a premier choice for rain gardens or low-lying areas.
• Effortless Self-Sower: Will naturally drop seeds to thicken your wildflower patch year after year.
• Elegant & Airy: The fine-textured foliage and wiry stems create a soft, "misty" look in the garden that sways beautifully in the breeze.

1. Sowing the Seeds:
Tickseed is incredibly easy to grow and has a high germination rate.

• When: Direct sow in early spring as soon as the danger of frost has passed. In the South, sow in the fall for winter and spring blooms.
• Depth: Surface sow and press firmly into the soil. Do not cover deeply, as the seeds require light to germinate.
• Germination: Expect sprouts in 10–15 days.

2. Choosing the Perfect Spot:
Select a location with Full Sun. While it can tolerate very light shade, the stems will be sturdier and the blooms more numerous in the brightest spot of your garden. It is the perfect choice for the edges of ponds, ditches, or garden beds that stay a bit damp.

3. Maintenance:

• Spacing: Thin seedlings to 8–12 inches apart. They look best when planted in dense "drifts."
• Watering: Keep the soil moist during the first few weeks. Once established, they can handle brief dry spells, but they prefer consistent moisture.
• Deadheading: To keep the plant looking tidy and to encourage even more flowers, snip off the faded blooms.

Leavenworth’s Tickseed looks breathtaking when paired with the deep blues of Ohio Spiderwort or the purple spikes of Lance Selfheal. The golden-yellow "stars" of the Coreopsis provide a high-contrast pop of color that makes a native meadow look professionally designed.

Garden Tip: If your plants get too tall or "leggy" mid-season, don't be afraid to shear them back by one-third. They will quickly respond with a flush of fresh green growth and brand-new flowers! ✂️☀️
