Orange crush — The Year of the Echinacea
In recent years echinacea has undergone a dramatic redesign. Long revered as a valuable native herb as well as a stalwart garden staple, gone are the days you could simply refer to it as purple cone flower. A veritable rainbow of colors are now represented in the echinacea palette, resulting in the National Garden Bureau naming 2014 as the Year of the Echinacea.
Today, more and more gardeners are seeking out perennial plants as long-term investments that offer good value at an effective cost. Perennials are the building blocks of any home garden and echinacea is at the top of the list.
According to the NGB, echinacea has been one of the varieties seeing a significant growth in breeding activity. It remains a “top five” perennial in terms of retail sales. Several advances have produced plants that have set a new standard in compact-growing, well-branched echinacea.
This good news means that breeding trials have resulted in bringing free-flowering plants to market that overwinter successfully in cooler zones — like right here for instance. Poor winter hardiness is a source of frustration with some gardeners. Historically, echinacea with bolder color hues (red, yellow, orange) have been grown from tissue culture liners. This propagation can lack good winter hardiness and may not bulk up in size in subsequent seasons. However, recent breeding has developed seed-grown varieties selected specifically for their bold coloring and trialed for overwintering success to USDA Zone 4.
One that has excelled in my garden is a yummy, fluffy-headed orange variety Secret Lust, bred by Terra Nova Nurseries of Oregon.
The NGB says that the coneflower is a native to central and eastern North America and is a member of the Asteraceae family. The U.S. Department of Agriculture recognizes nine distinct species of echinacea. Other flowers in the Asteraceae family include daisy, sunflower and aster. The name “Asteracea” finds its origin from the Greek word for star. The main family feature is its composite flower type: Its capitula (flower head) is surrounded by involucral bracts. Most echinacea blooms are oversized bright disks atop rings of downward-curving petals. The name “echinacea” is also derived from the Greek word “echino,” which means spiky or prickly, referring to the plant’s floral center. The florets are hermaphroditic, with both male and female organs on each flower. Pollination occurs most often with the help of butterflies and bees.
The plant prefers loamy, well-drained soil, but it is little affected by soil pH. Cultivated echinacea offer reliable performance as a perennial plant under a wide variety of conditions. Echinacea can be propagated from seed or vegetatively using various techniques, such as division, basal cuttings or root cuttings. Echinacea are generally low maintenance. Plant in full sun. Dividing every few years will keep the plants healthy. No additional fertilizing is necessary as heavy fertilization leads to tall, leggy plants that flop. Also, avoid over-watering as echinacea prefer drier conditions once established. While most home garden echinacea is ornamental, it can be grown as a fresh or dried cut flower. Allow flowers to mature on the plant before harvesting. Dry by hanging upside down in a well-ventilated, dry area. Fresh echinacea has a short vase life of seven days.
Echinacea may be affected by slugs, Japanese beetles, Bacterial Leaf Spot, Powdery Mildew, or botrytis. And are generally considered to be deer-resistant. For best visual impact, plant in masses. Deadhead florets to encourage further blooms. Echinacea flowers through the summer (June through August). Its seed heads can be left to dry on the plant to feed wild birds through the fall and winter. Echinacea plants will reseed in the fall, with new flowers growing the following season. Hardiness zones vary by variety, with a range from USDA Zone 4-9.
Started from seed, echinacea will flower in 11-15 weeks so if started indoors early enough, it is possible to get flowers in the first season. With most varieties, sow seeds indoors 8-10 weeks before outdoor planting date. Plant the seeds 1/8-inch deep in soilless growing medium. Cover lightly with 1/4-inch fine soil and keep moist at 65-70 F. Seedlings should emerge in approximately 10-20 days. As with most seedlings, you can transplant them to larger containers when seedlings have at least two pairs of true leaves. Before transplanting the young plants to the outside garden, harden off by exposing the plants to outdoors for gradually increasing time frames.
According to NGB: Herbalists use the roots/rhizomes and herbs of Echinacea to treat or ward off various infections and maladies. It offers a general boost to the immune system, and has antidepressant properties. Echinacea angustifolia was used by Native Americans to soothe sore throats, headaches or coughs — symptoms of the common cold. They first saw the benefit of using echinacea medicinally by observing elk that sought out the plant and ate it when wounded or sick. In the mid-19th century echinacea was used as a pain reliever and increased in use as an herbal medicine through the 1930s in America and Europe. The plant E. purpurea contains the chemical compounds cichoric acid and caftaric acid. These phenols are common to many other plants. Other phenols include echinacoside (found in E. angustifolia and E. pallida roots). These phenols can serve as markers for the quantity of raw echinacea in the product. Other plant components that contribute to health effects include alkylamides and polysaccharides.
