Ensure adequate moisture as growth begins. Remove any winter mulch if it blocks emerging shoots. Watch for slugs and snails.
Vegetative Growth
2-3 weeksDelicate, fern-like blue-green foliage develops on slender stems, reaching 6-10 inches tall

Flowering
3-4 weeks (March-April typically)Distinctive pink and white bicolor flowers bloom in tight racemes; petals have pink coloring with white-tipped upper petals
Deadhead spent flowers to encourage continued blooming, though plants may decline naturally as temperatures warm. Keep soil moist.

Fun Facts
- 🌱 Corydalis solida tubers are sometimes confused with miniature crocus corms but can be distinguished by their irregular, knobby shape and the presence of basal leaves.
- 🌱 The name 'Corydalis' comes from the Greek word 'korydalos,' meaning lark, because the spurred flowers resemble a lark's head.
- 🌱 This species is a spring ephemeral, evolving to complete its above-ground cycle quickly before tree canopy leafs out and blocks light in woodland habitats.
