Coreopsis UPTICK™ RED 'Baluptred' tickseed
Symbivit Tric (arbuscular)
Symbivit (arbuscular)Coreopsis
The genus Coreopsis, described by Carl Linnaeus in 1753, comprises nearly forty predominantly North American species that evolved in open prairies, on dry slopes and along moist margins of wetlands, and this ecological breadth explains their present-day reliability in gardens. Linnaeus chose a name derived from the Greek koris and opsis, meaning “the appearance of a bug”, because the dry achenes resemble tiny insects, a small example of his observational humour. The taxonomy of the genus was not always settled and in 18th and 19th centuries various synonyms appeared, such as Calliopsis and Acispermum, before modern revisions unified the group, particularly the work of Ernest E. Sherff (1882–1966). Coreopsis holds strong place in American culture: Coreopsis tinctoria was used by Indigenous peoples for dyeing textiles, and several US states have chosen different species as their official flowers – Florida, Mississippi, Tennessee and Maryland.
Hybrid tickseeds represent a broad group of interspecific hybrids created by combining several North American species, each contributing specific traits to the final genetic mix. C. grandiflora increases flower size and ensures an early start to flowering, C. lanceolata adds stem strength, drought tolerance and the ability to grow in poor soils, C. tinctoria provides genetic variability and a wide colour range, C. rosea contributes pastel shades and a finer texture, and C. verticillata supplies a fibrous root system that improves winter survival and reduces the risk of rot. Breeding and selection are carried out under conditions of high humidity, summer drought and temperature fluctuations in order to eliminate lines prone to the typical weaknesses seen in some coreopsis. Most modern hybrids are partially or fully sterile, which prolongs the flowering period and maintains a more compact habit without self‑seeding. The result is a group of plants well adapted to variable European climates, where winter moisture, summer heat and irregular rainfall alternate throughout the season.
UPTICK™ RED showcases rich, dark red flowers that shift in appearance over the season — the initial flush is nearly solid red, while later blooms feature golden-yellow petal tips. The daisy-like flowers have smooth, slightly rounded petals and appear from early summer until the first frost. Upright stems reach 30–35 cm in height and form compact, dense clumps. The foliage is narrow, medium green, three-lobed, and highly resistant to powdery mildew and common diseases. Thanks to its intense coloration and exceptionally long blooming period, UPTICK™ RED reliably fills the role of annuals that fade after a single season.
The UPTICK™ series of perennial tickseed originates from Ball Horticultural Company in Santa Paula, California, where it is bred by Blair Winner. With over four decades of experience in the ornamental plant industry, Winner has contributed to the development of dozens of popular cultivars — from geraniums and gazanias to tickseeds — for renowned companies such as Bodger Seed, PanAmerican Seed, and Ball Horticultural. Beyond ornamental breeding, he has also worked on nutrition-related projects, including marigold varieties with high levels of zeaxanthin used in dietary supplements that support eye health. His work has shaped modern horticulture across continents, and the UPTICK™ series reflects his pursuit of compact, floriferous, and disease-resistant plants with vibrant flower colours. The variety is protected under U.S. Plant Patent PP33866, granted in 2022.

Thread‑leaf tickseed and their hybrids are reliable perennials provided their origins are respected: they require sunny, open and well‑ventilated sites. They need full sun and a free‑draining soil that must never remain permanently wet, as this leads to loss of vigour and makes the plants prone to winter rot. Watering is necessary only during periods of extreme drought, since they are naturally adapted to alternating wet and dry conditions. They do not require feeding, or only a light application of compost in spring, because overly rich soils and the use of artificial fertilisers result in lush but unstable growth and eventual weakening of the plant. Removing spent flowers together with their stems helps to prolong the flowering period and maintains a clean, tidy appearance. The entire plant should be cut back to about 3–5 cm above ground level in spring once all frosts have passed. They are not reliably long‑lived in containers. Wind and exposed positions do not trouble them. Hardiness varies slightly between cultivars, but most tolerate around minus 29 °C (USDA zone 5), which means they overwinter without difficulty in typical Central European conditions and require no special protection.

- STANDARD QUALITY - Plants of this group are 1st class quality with number of branches and overall density adequate to their size and age, considering they were container grown.
- DE LUXE QUALITY - This label guarantees a luxurious quality of manually selected plants that, compared to their height and age, are exceptionally dense and beautiful.
- EXTRA - These plants are usually mature and bigger specimens with exceptional overall appearance.
- STANDARD (as described in the plant form) means a tree with a trunk of 190-210 cm and a crown at the top, unless specified differently. The commercial size for trees is their girth measured in the height of 1m from ground.
- HOBBY - These plants are of the same quality as our standard-quality plants but younger and therefore cheaper.
- SHRUB - a woody plant with branches growing bushy from the ground level.
- HALF-STANDARD or MINI-STANDARD - a small tree with shorter trunk, its size is usually specified.
- FEATHERED - These are trees with branches growing already from the base of the trunk and up along the stem.
- GRASSES and PERENNIALS - Sizes given usually read the diameter of the pot or the clump, as specified.
