Growth Stages

1

Dormancy & Emergence

March-May (varies by zone)

Plant is dormant underground over winter; new shoots emerge from crown in spring as soil warms

Remove old foliage in early spring before new growth appears. Watch for slugs as new shoots emerge. Apply fresh mulch.

2

Vegetative Growth

May-June

Rapidly expanding heart-shaped green leaves unfurl, creating a mounded plant form with increasingly lush foliage

Keep consistently moist. Monitor for slug and snail damage. Remove any flower buds if you want to redirect energy to foliage. Fertilize monthly with balanced fertilizer.

3

Flowering

July-August

Tall flower stalks (scapes) emerge from the center of the plant bearing delicate white or pale lavender flowers

Flowers appear in mid-to-late summer. Deadhead spent flowers unless you want seeds. Flowers attract pollinators and hummingbirds. Continue regular watering.

4

Maturation

August-September

Plant reaches full size and density; foliage deepens in color as plant settles into its environment

Foliage reaches peak lushness. Continue regular watering and feeding through summer. Prepare for dormancy by reducing fertilizer in late summer.

5

Dormancy

October-March

Foliage yellows and dies back as temperatures cool; plant retreats underground for winter

Cut back dead foliage in late fall or early spring. Apply 1-2 inches of mulch for winter protection in colder zones. Do not disturb the crown.
