Overview
Coreopsis (Coreopsis spp.), also called Tickseed, is one of the longest-blooming perennials available, often flowering from late spring all the way through fall with minimal care. The Uptick series — Gold & Bronze and Red — features semi-double blooms with distinctive bicolor markings on compact, mounding plants. Native to North America and extremely adaptable.
Sun & Exposure
- Ideal: Full sun (6+ hours daily)
- Tolerated: Light shade, but flowering will be noticeably reduced
- Thrives in hot, sunny conditions that stress other plants
Watering
Coreopsis is a true drought-tolerant perennial once established.
- Water regularly during the first growing season to establish roots
- Established plants need watering only during extended drought
- Excellent drainage is important — will not tolerate wet feet
Soil & Planting
- Tolerates poor, sandy, or rocky soils — thrives where other plants struggle
- Does not require rich soil; too much fertility causes floppy growth
- Plant in spring or fall; space 12–18 inches apart
- Slightly acidic to neutral pH (6.0–7.0)
Fertilizing
Coreopsis rarely needs fertilizing. Rich soil or excess fertilizer leads to floppy plants with fewer flowers.
- A light application of balanced fertilizer in early spring is sufficient if soil is very poor
- Generally, no feeding is needed in average garden soil
Pruning & Deadheading
- Deadhead regularly to keep plants blooming through the season
- Shear plants back by one-third in midsummer if flowering slows — this triggers a flush of new blooms
- Leave some seed heads in fall for goldfinches
Winter Care
Hardy in zones 4–9. Leave foliage in place over winter for some crown protection; cut back in early spring. May die out in very wet winters — good drainage is the best prevention.
