“…Many of these biologically designed landscapes incorporate herbaceous ornamental perennial cultivars due to their naturalistic style, comparative limited breeding history, and low input cultivation requirements 29 . Nonetheless, many of these varieties have undergone hybridization and artificial selection to create floral phenotypes based on consumer, rather than pollinator, preference 30 and thus their utility to pollinators remains to be determined. Human selection in ornamental plants has generated a diversity of cultivars that vary in color, bloom size and duration, and morphology, all of which are important regulators of pollinator learning and choice behavior 12 , 31 , 32 .…”

Human-designed landscapes can host diverse pollinator communities, and the availability of floral resources is central to supporting insect biodiversity in highly modified environments. However, some urban landscapes have relatively few pollinator-attractive plant species and management in urban environments rarely considers the function of these plants in generating and supporting a stable ecological community. Evaluations of 25 cultivars within five commercially popular herbaceous perennial ornamental plant genera (Agastache, Echinacea, Nepeta, Rudbeckia, and Salvia) revealed variation in the total and proportional abundance of visitors attracted. These varieties supported multiple pollinator functional groups, however bees were the primary visitors to in this system. Cultivars were assessed according to their function within a plant–pollinator network. Comparisons of artificial networks created with the six most attractive and six least attractive cultivars demonstrated that a planting scheme using the most attractive cultivars would attract nearly four times as many bee species, including several specialists and rare species. Plant diversity in the landscape was correlated with abundance and diversity of pollinator visitors, demonstrating that community context shapes a plant’s relative attractiveness to pollinators. We conclude that herbaceous perennial cultivars can support an abundance and diversity of pollinator visitors, however, planting schemes should take into consideration the effects of cultivar, landscape plant diversity, floral phenology, floral area, and contribution to a stable ecological community.

“…Botanic gardens are also actively involved in this work. The Chicago Botanic Garden has, for example, been using wild collected germplasm and cultivated plants from nursery sources to produce improved garden plants of false indigo (Baptisia) and coneflowers (Echinacea) that are more suitable for the Midwest (Ault 2003).…”

“…Conventional selective breeding techniques have traditionally led to the gradual improvement of many plant species. While industry will undoubtedly continue to develop “improved” varieties, published Echinacea breeding studies (and patents) have focused primarily on ornamentals (Ault 2002 ; Korlipara 2008 ) and reducing seed dormancy (Qu and Widrlechner 2012 ). Traditional selective breeding of Echinacea can make use of the existing genetic and phenotypic variation in commercial and wild collected plants and is widely accepted by the public, including within the organic farming industry.…”

Context: Plants of the genus Echinacea (Asteraceae) are among the most popular herbal supplements on the market today. Recent studies indicate there are potential new applications and emerging markets for this natural health product (NHP).Objective: This review aims to synthesize recent developments in Echinacea biotechnology and to identify promising applications for these advances in the industry.Methods: A comprehensive survey of peer-reviewed publications was carried out, focusing on Echinacea biotechnology and impacts on phytochemistry. This article primarily covers research findings since 2007 and builds on earlier reviews on the biotechnology of Echinacea.Results: Bioreactors, genetic engineering and controlled biotic or abiotic elicitation have the potential to significantly improve the yield, consistency and overall quality of Echinacea products. Using these technologies, a variety of new applications for Echinacea can be realized, such as the use of seed oil and antimicrobial and immune boosting feed additives for livestock.Conclusions: New applications can take advantage of the well-established popularity of Echinacea as a NHP. Echinacea presents a myriad of potential health benefits, including anti-inflammatory, anxiolytic and antibiotic activities that have yet to be fully translated into new applications. The distinct chemistry and bioactivity of different Echinacea species and organs, moreover, can lead to interesting and diverse commercial opportunities.
