Dormancy
June-AugustCorms rest underground in summer after foliage dies back completely.
Plant new corms in fall (September-November). Ensure soil remains cool and dry during summer dormancy. No watering needed.
Root Development
September-FebruaryRoots emerge from the corm during autumn and winter as soil temperatures cool.
Plant corms in fall when soil temperature drops below 60°F. Ensure good drainage to prevent rot. Light autumn watering helps root establishment.
Emergence
Late February-MarchMottled leaves and flower buds push through soil as temperatures warm in early spring.
Ensure adequate moisture as growth accelerates. Apply balanced fertilizer once shoots appear. Protect from late frosts if needed.
Flowering
March-AprilPurple reflexed flowers bloom on 4-6 inch stems, typically producing one flower per corm. Marbled foliage is prominently displayed.
Allow flowers to fully develop and fade naturally. Deadhead spent flowers but leave foliage intact to feed the corm. Keep soil consistently moist.
Senescence
May-JuneFoliage gradually yellows and withers as the plant redirects energy back to the corm for next season.
Continue watering until foliage completely dies back. Do not cut foliage prematurely. Stop fertilizing and allow natural senescence.

Fun Facts
- 🌱 The common name 'dog's tooth violet' refers to the fang-like pointed corm, not to the flower's resemblance to a violet. The name is misleading—it's actually a lily relative, not a true violet.
- 🌱 Purple King corms require a period of cold temperatures (winter chilling) to bloom properly, making them ideal for northern gardeners but challenging in warm climates.
- 🌱 The mottled or marbled foliage pattern is unique among spring bulbs and provides ornamental interest even before and after flowering.
