Chrysanthemum zawadskii
Chrysanthemum zawadskii is a hardy, clump‑forming species with clean white daisies and yellow centers. It stands out for earlier bloom that can start in midsummer and continue into early fall. It performs best in full sun and moist, well‑drained soil. Plants stay compact and branch well if pinched once in early summer. It overwinters reliably in much of the northern U.S. where many florist mums do not.

Care in one minute
- Plant in full sun with fertile, well‑drained soil.
- Water during dry spells to sustain bloom.
- Pinch once in early summer to keep compact and delay peak bloom to late season.
