The Zagreb Coreopsis (Coreopsis verticillata 'Zagreb') is a perky little prolific bloomer that fills gardens with bright yellow blooms! With a bonanza of blossoms that flower from June through October. Also known as a Threadleaf Coreopsis, these feature incredibly fine-textured leaves that appear as green mist along sunny borders and beds!
With a deeper golden-yellow flower on a more compact plant than other Tickseed, this sunny flower readily reblooms! The bright ray petals around a tufted center seem to shine in the sunlight.
The lacy, fine-textured foliage is a wonderful deep-green, forming rounded, spreading clumps of even branching. Remaining lovely until frost when these herbaceous perennials die back to the ground. Zagreb is a little shorter than the rest of the Coreopsis family. Meaning you can always fit one or two into your garden!
And your pollinators and butterfly population will thank you! Flocking in droves to these sunny blooms, they are a nectar boon for hungry bees that desperately need our help! Just as hardy and tolerant as their native cousins, these tough plants can handle the heat, sun, cold and poor soil.
How to Use Zagreb Coreopsis In The Landscape
These are full sun perennials and are a great choice for poor, rocky soils. Tough plants when used as a mass planting in tricky locations along the roadside ‘hell-strip’ or your driveway. But graceful enough to line paths and walkways with misty greenery and yellow blooms.
Incorporate into mixed borders and as edging along your other plantings where the fine texture and compactness provides a clean, finishing touch at the front of your landscaping beds.
Use as definition and as a low hedge to provide a visual barrier along roadsides and sidewalks. Their hardiness and love of the sun, plus the neat mounds Zagreb forms, make them wonderful additions to Rock gardens and Cottage gardens.
Small cut flowers, you can add these as filler to both your bouquets as well as in containers and planters! Zagreb should be planted in full sun and looks great on sunny patios, porches and balconies!
Coreopsis Zagreb looks great with any type of grass or other fine-textured perennial. Fantastic in naturalized, prairie areas wildflower gardens.
No garden should be without it and with its diminutive size, you'll easily find a place for it!
#ProPlantTips For Care
Enjoying the full sun, Coreopsis thrives in hot sunny sites. Be sure to provide at least 6 hours of direct sunlight, favoring morning sun, per day. Hardy in USDA growing zones 3 through 9, these are very cold hardy!
Plant these in poor to average garden conditions to soils of moderate fertility with a focus on well-drained soils. It is drought-tolerant once established and tough, thriving in poor, rocky or gravel soil, but it does need to be well-drained.
Water moderately and consistently while young plants are establishing, but afterward, these are very water-wise Xeriscaping plants. Deer resistant and resistant to powdery mildew, these easy-to-grow beauties!
It is recommended you deadhead the spent flowers, by cutting them back early and late summer to extend the bloom period and promote a fall flush of blooms. By pruning to the ground each year in early spring, this perennial will produce all new fresh growth from the roots.
This long-lived Winner of the 2001 RHS Award of Garden Merit, the Zagreb Coreopsis has been proven as an outstanding perennial to add to your landscape this year! Order at NatureHills.com today!
