Peduncle — Echinacea purpurea

In breeding and variety testing, the height of the Echinacea peduncle is measured in centimeters. Compact ornamental forms reach 30–60 cm, while typical species plants and medicinal varieties range from 70–120 cm, growing up to 150 cm under favorable conditions. An important characteristic is the strength of the peduncle, which determines the plant's resistance to lodging from wind and rain.

For the industrial cultivation of medicinal raw materials, peduncle height and its foliage are directly correlated with the yield of aerial biomass and determine the choice of mechanized harvesting technologies. In ornamental gardening, shoot strength is important for maintaining the plant's habit and use in cut flowers, as well as preserving its ornamental value during the winter period. When growing young plants, removing the peduncle in the first year is used as a technique to optimize root system development and ensure successful overwintering.
