Plant

Fall-plant bare-root divisions. CRITICAL: eyes must be 1–2" below the soil surface. Deeper and they'll never bloom.

Care

Ants on buds are normal — they eat sweet exudate, don't harm the plant. Cut foliage to ground in fall. Almost immortal once established.

Harvest

Cut when buds are soft (the 'marshmallow' stage) — they'll open in the vase and last a week. Store dry in fridge for weeks.

Preserve

Cut buds can be stored dry in the fridge for up to 6 weeks — a florist trick to extend the short season.
