Purple coneflower Echinacea purpurea 'Rubinstern'
ABOUT
Echinacea purpurea 'Rubinstern', also known as Ruby Star coneflower, is a striking perennial known for its showy flowers and robust constitution. It boasts a clump-forming habit with sturdy stems that distinctly hold up its flower heads without drooping. The leaves of Ruby Star coneflower are dark green, broad, and coarsely toothed, providing a lush backdrop for the blossoms. The most captivating feature of this coneflower is its radiant and large daisy-like flowers. Each bloom consists of a prominent, raised cone center that's deep orange to reddish-brown in color, which gives a rich, textured look and lends the plant its common name. Surrounding the cone are petals that are typically a deep pink to ruby red hue, radiating outward and slightly drooping, creating a sense of elegance and softness. This coneflower variety is particularly noted for its vibrant and long-lasting blooms, which generously adorn the plant throughout the summer months and often into fall, providing a continuous display that brings life and color to the garden. The flower heads also attract butterflies and bees, adding movement and interest, and later on, they become a food source for birds that feast on the seeds. When not in bloom, the plant maintains a lush mound of foliage that remains attractive through the season, making it a valuable addition to the garden even when not displaying its striking flowers. Its overall appearance is one of resilience and enduring beauty, making it a popular choice for gardens aiming for a natural, yet refined aesthetic.

WaterConeflowers, such as the 'Rubinstern' Echinacea purpurea, should be watered deeply but infrequently to encourage deep root growth. Provide at least 1 inch of water weekly if there has been no rain, which equates to roughly 0.623 gallons per square foot. During hot, dry spells, increase watering to twice a week. Avoid overhead watering to reduce the risk of fungal diseases, and instead aim the water at the base of the plant. Ensure that the soil drains well, as coneflowers do not like to be waterlogged.
LightConeflowers like 'Rubinstern' Echinacea purpurea thrive in full sun, requiring at least 6 hours of direct sunlight daily. A spot in the garden that receives bright, unfiltered light for most of the day is ideal. They can tolerate some partial shade, especially in hotter climates, but flowering may be reduced in less than full sun.
TemperatureConeflowers, such as the 'Rubinstern' Echinacea purpurea, do well in a wide temperature range and can tolerate summers with high temperatures above 85°F. They can survive winter temperatures down to at least -20°F. Ideal growth occurs in temperatures between 65°F and 70°F during the growing season. Coneflowers are hardy and adaptable to various weather conditions, but prolonged exposure to extreme temperatures outside their tolerance range can be harmful.
PruningPruning 'Rubinstern' Echinacea purpurea encourages further flowering and helps maintain a tidy appearance. Deadheading spent flowers throughout the blooming season can stimulate new blooms. After blooming has finished in the fall, you can prune back the stems to the ground, although some gardeners leave the seed heads to provide winter interest and food for birds. Clean, sharp shears should be used to make precise cuts.
CleaningAs needed
SoilConeflower prefers well-draining soil enriched with compost; it thrives in a soil pH of 6.0 to 8.0.
RepottingConeflowers are typically not repotted as they are perennials that are best grown outdoors; dividing every 3-4 years is recommended.
Humidity & MistingConeflower is tolerant of a wide range of humidity levels and thrives in outdoor conditions without requiring special humidity adjustments.
Suitable locationsIndoor
Ensure full sun, well-draining soil; coneflower seldom grown indoors.
Outdoor
Plant in full sun, well-draining soil, space 1-2 feet apart.
Hardiness zone
3-9 USDA.
Life cycleThe life of the coneflower 'Rubinstern' begins with seed germination, which occurs in late winter to early spring when the soil temperature reaches an appropriate level, usually between 65-70°F. Once the seeds germinate, the seedlings emerge and start to develop their first true leaves, entering the vegetative growth stage during which they establish a strong root system and foliage. After a period of vegetative growth, typically in its second year, the coneflower reaches the flowering stage in summer, producing striking ruby-red to purplish flowers with a prominent central cone that attract pollinators. Following pollination, the flowers develop into seed heads that dry out as the plant matures, marking the plant's reproductive phase. These seeds can be dispersed by wind or wildlife, promoting the spread of new plants for the following season. In fall to winter, the coneflower enters dormancy, with the above-ground parts dying back and the plant surviving as roots or basal rosettes until the next spring.
PropogationPropogation time
Spring-Early Summer
Echinacea purpurea 'Rubinstern', commonly known as Purple Coneflower, is frequently propagated through seed sowing. This method is popular due to its simplicity and effectiveness. Seeds can be sown in fall or early spring, directly into a well-drained soil mix. Covering the seeds with a thin layer of soil—about 1/4 inch (approximately 6 millimeters)—and ensuring consistent moisture without waterlogging, will promote germination. Seedlings will typically emerge in 10-20 days, after which they can be thinned out and transplanted when they’ve developed a few true leaves. It should be noted that while seed propagation is commonly used, it might not always yield offspring that are true to the 'Rubinstern' cultivar's specific characteristics due to genetic variability.
