Topeka Purple Coneflower problems — and how to fix them
Topeka Purple Coneflower (Echinacea atrorubens) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slow establishment from seed
Seeds require 8 weeks of cold moist stratification and plants typically do not flower until year 2 or 3; impatient gardeners may mistake slow growth for failure — patience and correct stratification are key.
Eriophyid mite damage
Tiny mites feeding on developing buds cause misshapen, stunted flower heads and distorted foliage; infestations are invisible to the naked eye — treat with sulphur-based miticide or horticultural oil at first sign of distorted growth.
