Hybrids between Echinacea purpurea (L.) Moench and Echinacea paradoxa (Norton) Britton
The frost resistance of these hybrids is assessed via USDA zones and is characterized by varying levels of winter hardiness. The primary factor for survival is the resistance to crown rot resulting from the combination of low temperatures and soil waterlogging.
In the reference 8 varieties crop Hybrids between Echinacea purpurea (L.) Moench and Echinacea paradoxa (Norton) Britton, where this is mentioned in the description.
The trait of frost resistance in E. purpurea × E. paradoxa hybrids is evaluated primarily through long-term field observations rather than instrumental measurements. While E. purpurea provides high resistance (zones 3–4), hybrids often inherit lower frost resistance traits from E. paradoxa (zones 5–8), which makes them less perennial in cultivation.
A critical condition for the overwintering of hybrids is not so much the minimum temperature as it is soil moisture. Waterlogging during the winter period leads to crown rot, so to increase survival rates, ideal drainage must be ensured and deep planting of the crown must be avoided.
