Coreopsis ‘Red Satin’

Coreopsis 'Red Satin' is a compact, clump-forming perennial tickseed with fine-textured foliage and wine-red to ruby-red flowers with golden centers. It belongs to the Permathread™ series and is valued for long flowering and low maintenance.

Coreopsis 'Red Satin' grows best in full sun, ideally with at least 6 hours of direct light daily. Light afternoon shade may help in very hot climates, but too much shade can reduce flowering and cause weaker growth.

Water Coreopsis 'Red Satin' regularly during its first growing season, then reduce watering once it is established. It is drought tolerant but benefits from supplemental water during prolonged heat or dry spells.

Use well-drained sandy, gravelly, rocky, or average loam soil for Coreopsis 'Red Satin'. Avoid persistently wet or heavy clay soil because poor drainage can lead to crown or root rot.

Coreopsis 'Red Satin' typically grows about 15 to 18 inches tall and 18 to 24 inches wide. Its compact, mounded habit suits border fronts, edging, mass plantings, and containers.

Yes, Coreopsis 'Red Satin' is generally grown as a herbaceous perennial in USDA Zones 5 through 9. Winter survival can be less reliable in exposed sites, poorly drained soil, or outdoor containers.

Coreopsis 'Red Satin' is commonly listed for USDA Hardiness Zones 5 through 9. Established plants may tolerate temperatures near 5°F, but local winter exposure and drainage strongly affect survival.

Yes, established Coreopsis 'Red Satin' is drought tolerant and performs well in dry to moderately moist soil. Water it more consistently while newly planted and during unusually long periods of heat and drought.

Coreopsis 'Red Satin' can tolerate some partial shade, particularly in very hot regions, but full sun produces the strongest flowering and best flower color. Plants in too much shade may become less floriferous or floppy.

Yes, Coreopsis 'Red Satin' is well suited to relatively poor, dry, sandy, rocky, or average soil. Excessively rich soil is unnecessary and may encourage lush, weaker growth rather than better flowering.

Yes, Coreopsis 'Red Satin' grows well in a container with drainage holes and a fast-draining potting mix. Container plants dry out faster than plants in the ground and may need winter protection in cold climates.

Coreopsis 'Red Satin' is generally considered resistant to deer and other browsing herbivores. Deer resistance is not absolute, especially when food is scarce.

Yes, the flowers of Coreopsis 'Red Satin' attract butterflies and other flower-visiting pollinators. Its sterile flowers do not produce viable seed, so it provides floral resources without readily self-sowing.

Give Coreopsis 'Red Satin' full sun, well-drained soil, and regular water while it establishes. After establishment, keep watering moderate and avoid excessive fertilizer or constantly wet conditions.

Insufficient sunlight is a common reason Coreopsis 'Red Satin' blooms poorly. Other possibilities include excessive nitrogen, drought stress, overly wet soil, transplant shock, or cutting the plant back before flower buds develop.

Coreopsis 'Red Satin' may sprawl in hot, humid weather, after heavy summer rain, or when grown in too much shade. Shearing after the first flush of flowers or using a discreet plant support can help maintain a compact shape.

Coreopsis 'Red Satin' usually needs little fertilizer when grown in average soil. If growth is weak, apply a light amount of balanced or slow-release fertilizer in spring, but avoid heavy nitrogen applications.

Yellow leaves on Coreopsis 'Red Satin' most often indicate overly wet soil, poor drainage, or normal seasonal decline. Check the root zone before watering again and improve drainage if the soil stays wet.

Coreopsis 'Red Satin' is generally resilient, but crown rot, powdery mildew, botrytis, fungal leaf spots, and aster yellows can occur. Good air circulation, well-drained soil, and removal of diseased plant material reduce risk.

Prevent crown rot by planting Coreopsis 'Red Satin' in sharply drained soil and avoiding frequent watering when the soil is already moist. Do not bury the crown deeply or place the plant where water collects.

Plant Coreopsis 'Red Satin' in spring after the soil can be worked or in early fall at least several weeks before the ground freezes. Spring planting is preferable in colder areas or sites with severe winter exposure.

Space Coreopsis 'Red Satin' about 18 to 24 inches apart, depending on whether you want individual mounds or quicker coverage. Allowing air movement between plants helps reduce foliage problems.

Plant Coreopsis 'Red Satin' at the same depth it was growing in its nursery container, with the crown level with the surrounding soil. Planting too deeply can restrict drainage and encourage crown problems.

Coreopsis 'Red Satin' can struggle in heavy clay unless drainage is improved. Plant it in a raised bed or amend the site appropriately, while avoiding a planting hole that becomes a water-holding pocket.

Coreopsis 'Red Satin' can gradually expand by rhizomes, but it is not usually considered aggressive. Its sterile flowers do not produce viable seed, so unwanted spread mainly comes from clump growth rather than seedlings.

The most reliable way to propagate Coreopsis 'Red Satin' is by dividing established clumps in spring. Seed is not a dependable method because this cultivar is sterile and does not normally produce viable seed.

Coreopsis 'Red Satin' generally cannot be reproduced reliably from seed because its flowers are sterile. Use division or nursery-propagated plants to maintain the cultivar's characteristic flower color and form.

Divide Coreopsis 'Red Satin' in spring as new growth begins, when the plant can recover quickly. Division may be useful every 2 to 3 years if the clump becomes crowded or loses vigor.

Deadhead Coreopsis 'Red Satin' to improve its appearance and encourage continued flowering. Removing spent blooms is optional because the cultivar is sterile, so it will not readily reseed.

Shear Coreopsis 'Red Satin' after the first major flush of flowers to remove sprawling growth and encourage rebloom. In late winter or early spring, cut the remaining stems back near ground level before new growth resumes.

Coreopsis 'Red Satin' is generally regarded as non-toxic to dogs and cats. Pets can still experience stomach upset after eating large amounts of any plant, so contact a veterinarian if concerning symptoms occur.

Coreopsis 'Red Satin' usually blooms from early or midsummer into late summer, and it may continue into fall when regularly deadheaded or sheared. Exact timing varies with climate, planting date, and weather.

Coreopsis 'Red Satin' produces deep wine-red to ruby-red daisy-like flowers with contrasting golden to orange-gold centers. Flower color is usually richest when the plant receives full sun.

Yes, Coreopsis 'Red Satin' can rebloom after spent flowers or the first flush of growth is cut back. Shearing in midsummer often produces a tidier plant and another round of flowers before frost.

Yes, Coreopsis 'Red Satin' can be used as a cut flower because its stems carry long-lasting daisy-like blooms. Cut stems when flowers are freshly open and remove foliage that would sit below the waterline.
