Dormancy
November-FebruaryUnderground corms rest in winter; no visible above-ground growth
Ensure adequate cold period (vernalization); no watering needed. Protect corms from rodent damage.
Emergence
March-AprilMottled, lance-shaped leaves emerge from soil in early spring; distinctive brown and white variegation on foliage
Keep soil moist as new growth appears. Mulch lightly to retain moisture and moderate soil temperature.
Flowering
April-MayDelicate, nodding yellow flowers (6 reflexed petals) appear above foliage; typically one flower per stem
Allow flowers to develop fully and set seed. Avoid disturbing plants during bloom. Maintain consistent moisture.
Seed Development
May-JuneFlowers fade and seed pods develop and mature; foliage remains green and active
Allow seeds to mature fully before deadheading. Seeds can be collected when pods split open.
Senescence
June-OctoberFoliage yellows and dies back as plant enters dormancy; corms build energy reserves underground
Allow foliage to remain until it naturally dies back. Continue light watering until plants yellow completely.

Uses
Early Pollinator Food Source
WildlifeProvides nectar and pollen for early spring bees, butterflies, and other insects emerging from winter dormancy. The flowers are particularly valuable in woodland gardens lacking other early bloomers. [source]
Woodland Garden Ornamental
HouseholdPrized for naturalized woodland plantings, shade gardens, and native plant landscaping. The mottled foliage and delicate flowers create elegant spring displays in shaded areas where few other plants thrive. [source]
Traditional Native American Uses
MedicinalHistorically used by Native Americans to treat skin conditions and wounds, though not commonly used in modern herbalism. Modern harvesting should be avoided to protect wild populations. [source]
Wildflower Seed Propagation
CraftValued by native plant enthusiasts for seed collection and propagation to establish new woodland gardens. Self-seeds readily when conditions are suitable, creating naturalized colonies. [source]

Harvest Tips
This is an ornamental wildflower not meant for harvesting flowers. Collect seeds in June when pods split open; sow immediately or store in cool, dry conditions. Corms can be divided in late summer after foliage dies back, but allow plants to establish for at least 3 years before division.
Fun Facts
- 🌱 The common name 'Canine's Teeth' refers to the pointed, tooth-like shape of the flower's reflexed petals and the mottled leaves that resemble spotted hunting dog coats.
- 🌱 Erythronium corms can live for several decades and produce only one leaf in their first years before developing the energy reserves needed to flower after 7-8 years.
- 🌱 Some plants in colonies produce thousands of seeds per year, yet population growth is slow because seeds require specific soil fungi and cold-moist stratification to germinate.
