Zagreb Coreopsis
Coreopsis verticillata 'Zagreb'
Zagreb Coreopsis is the one I’d choose when you want the fine texture of threadleaf Coreopsis but with a stronger golden-yellow flower color than Moonbeam. It is tough, bright, and easy to work into sunny borders, especially with coneflowers, salvia, yarrow, catmint, and ornamental grasses. I especially like it planted in groups near the front of a bed, where the color can repeat and carry the garden through summer with very little maintenance.

Golden Yellow Blooms for Sunny, Low-Maintenance Gardens
Golden yellow flowers with long summer color.
Zagreb Coreopsis produces bright golden-yellow, daisy-like flowers that bring cheerful color to sunny gardens from early summer into late summer. The flower color is deeper and bolder than Moonbeam Coreopsis, making Zagreb a great choice when homeowners want a stronger yellow impact in borders, pollinator beds, and low-maintenance perennial gardens. Its open, sunny blooms pair beautifully with purple, blue, orange, white, and grass-like textures, giving gardeners a dependable color anchor through the warm season.
Fine threadleaf foliage with an airy look.
This threadleaf Coreopsis forms a bushy yet lightweight clump of fine, needle-like green foliage, giving the garden a soft, airy texture. The foliage helps the plant blend easily with bolder perennials and ornamental grasses, preventing sunny borders from feeling too heavy or crowded. Even before and between bloom cycles, Zagreb Coreopsis adds a relaxed, meadow-like quality that works beautifully in cottage gardens, naturalistic plantings, pollinator borders, and rock gardens.
A pollinator-friendly perennial for full sun.
Zagreb Coreopsis attracts butterflies, bees, and other beneficial pollinators during its long bloom season, making it a useful addition to wildlife-friendly landscapes. Planting it in groups creates a stronger visual display and provides pollinators with a clearer landing zone in sunny beds. Its bright flowers and compact mounding habit make it especially useful near the front or middle of pollinator gardens, where it can repeat through the planting and carry color for weeks.
Tough, drought-tolerant, and deer-resistant.
Once established, Zagreb Coreopsis handles heat, humidity, dry soil, and lean garden conditions better than many fussier flowering perennials. It thrives in full sun and well-drained soil, including sandy, rocky, poor, or dry sites where richer-soil plants may flop or decline. It is also considered deer resistant, making it a practical choice for homeowners who want long-blooming color with better-than-average browsing resistance.
Easy to refresh for rebloom and tidy growth.
Zagreb Coreopsis is naturally low maintenance, but a little seasonal trimming helps keep it looking its best. Deadheading spent flowers or lightly shearing the plant after its first heavy bloom cycle can refresh the foliage, reduce legginess, and encourage additional bloom later in the season. Use it in masses, sunny borders, edging, containers, rock gardens, and dry garden plantings where bright color and easy care are both priorities.

How to Care for Zagreb Coreopsis
Before you buy a Coreopsis Zagreb Plant, make sure to read about the recommended care instructions to keep this plant healthy and thriving.
How should I plant Zagreb Coreopsis?
Plant Zagreb Coreopsis in full sun with well-drained soil. It can tolerate light shade, especially in very hot climates, but the strongest flowering usually happens where the plant receives at least 6 hours of direct sunlight per day. Dig a hole about twice as wide as the root ball and set the crown level with the surrounding soil. Backfill, water deeply, and space plants about 18 to 24 inches apart to allow the mounds room to mature and maintain good airflow.
How often should I water Zagreb Coreopsis after planting?
Water Zagreb Coreopsis regularly during the first growing season while the roots establish. Keep the soil lightly moist after planting, but avoid soggy conditions because Coreopsis performs best in well-drained soil. Once established, Zagreb Coreopsis becomes drought-tolerant and usually needs less supplemental water than many flowering perennials. During extended heat or drought, water deeply as needed, then allow the soil to dry slightly between waterings.
When should I fertilize Zagreb Coreopsis?
Fertilize Zagreb Coreopsis lightly in spring only if your soil is very poor. In most garden beds, compost or a light application of balanced, slow-release fertilizer is enough to support healthy growth and flowering. Avoid heavy fertilizing, which can encourage weak or floppy growth. Zagreb Coreopsis often performs best in average to lean soil with full sun and good drainage.
When and how should I prune Zagreb Coreopsis?
Prune Zagreb Coreopsis by deadheading spent blooms or lightly shearing the plant after its first heavy flush of flowers. This helps refresh the foliage, keep the mound tidy, and encourage additional bloom later in the season. Cut the plant back in late fall after frost or in early spring before new growth begins. If the clump becomes thin in the center after several years, divide the plant in spring to refresh growth.
