Growth Stages

1

Establishment

Spring through summer of first year

New plants develop roots and basal foliage; heart-shaped leaves emerge from soil

Keep soil moist; apply 2-3 inches of mulch; protect from direct sun and wind

2

Vegetative Growth

First full growing season through year 2

Foliage expands; plants form dense clumps; leaves may display bronze or red tones

Water consistently; allow foliage to grow naturally; deadhead spent leaves in early spring if desired

3

Flowering

4-6 weeks in spring (April-May in northern zones)

Delicate flowers with backward-facing spurs appear on thin stems above foliage; colors range from white, pink, red, to bicolors

Blooms typically appear in mid to late spring; flowers last 3-4 weeks; deadheading extends blooming

4

Seed Development

Late spring through summer

After flowering, seed pods develop and ripen; foliage continues to mature and deepen in color

Leave seedpods for self-seeding if desired; allow foliage to fully develop through summer

5

Dormancy

Fall through early spring (October-March)

Foliage yellows and dies back; plant enters winter rest; minimal above-ground activity

Cut back old foliage in late winter before new growth emerges; maintain mulch layer; reduce watering
