* Outside zones 3 to 9, the hardiness range our sources give for coneflowers. Plants there may not survive the winter or get enough winter chill, and are usually grown as annuals or in pots.

Where frost is rare

UF/IFAS notes that not every purple coneflower does well across Florida: some last only a year or two and then decline. Enriched, well-drained soil helps them last longer.
