Establishment
First 4-6 weeksYoung plants have limited root systems and small leaf growth. New foliage emerges with bronze or red tones.
Keep soil consistently moist. Apply 2-3 inches of mulch around plants. Avoid transplanting stress by protecting from wind.
Vegetative Growth
4-8 weeks in springHeart-shaped leaves expand and form dense mounds. Foliage may display variegation or color changes with temperature fluctuations.
Cut back old foliage in late winter before new growth emerges. This encourages fresh foliage and better flower displays. Water moderately.
Flowering
4-6 weeks, typically April-MayDelicate, orchid-like flowers with prominent spurs appear above foliage. Flowers bloom in shades of white, pink, purple, red, or bicolor combinations.
Flowers appear on new stems. Do not deadhead if you want seeds to develop. Provide consistent moisture to support flowering.
Seed Development
6-8 weeks after floweringFlowers fade and develop seed pods. Foliage matures and thickens.
Allow flowers to mature if seed collection is desired. Seeds can be collected when pods dry and split.
Dormancy
October-MarchPlants die back in fall and remain dormant through winter. Some foliage may persist in milder climates.
Remove old foliage in late winter to ground level. Apply light mulch for insulation in cold zones. Reduce watering.
