Las Cruces, N.M., is at an elevation of 3,891 ft (1, 186 m) and has an average of 220 frost free days per year, whereas Alcalde, N.M., is at an elevation of 5,719 ft (1,743 m) and averages 152 frost-free days per year. Active ingredients in Echinacea include polysaccharides, flavonoids, caffeic acid derivatives, essential oils, polyacetylenes, and alkylamides.įield studies were conducted to determine the production potential of echinacea (Echinacea purpurea), valerian (Valeriana officinalis), mullein (Verbascum thapsus) and yerba mansa (Anemopsis californica) medicinal herbs at two sites in New Mexico. Leaves are a source of valuable active ingredients, but no information is available in the literature on leaf harvesting. The best stage to harvest flowers has yet to be determined. Roots are harvested in the fall after 3 to 4 years of cultivation. Echinacea thrives under cultivation in moderately rich and well-drained loam or sandy loam soft with regular irrigation and weed control. ![]() Seed stratification for 4 to 6 weeks at 34 to 40 ☏ (1 to 4 ☌) before planting can improve germination. Echinacea can be propagated from seed, crown division, and root sections. Better cultural methods and standardization and quality control of the value-added products are needed to increase the confidence of growers, producers, and consumers in this promising medicinal herb. The cultivated acreage in the United States and Canada is increasing because of the great demand for Echinacea products. Fresh yield of herb, fresh yield of stem, fresh yield of leaf, dry yields of stem, dry yields of leaf, number of seconder buds (kg ha-1) had differences according to plant densities and years.Įchinacea species, a popular medicinal herb throughout the world, have been used by indigenous Americans for hundreds of years as an effective immunostimulant. Also, fresh weight of herb (g plant-1), dry weight of flowers (g plant-1) and number of main stems (number plant-1) were not changed in pertinent to years and plant densities. Although the weight of different aerial parts and roots per plant (g plant-1) were not changed according to different plant densities (30×90, 45×90, 60×90 cm) these parameters were changed according to the years. Purple coneflower were harvested at the aerial parts when the flowering time at the 2nd and 3nd season, roots were harvested in fall. ![]() Since flowering plants were not available for one-year-old plants in 2010. ![]() Plants were harvested in June, 20 as second and third seasons of growth in Cukurova. Here, Purple coneflower plants were grown in the Cukurova Region of Turkey and the effect of plant density and year on the herb yields were studied. Purple coneflower, one of the most popular medicinal plants, is not naturally found in Turkey.
