Growth Stages

1

Establishment (Spring - Early Summer Year 1)

6-8 weeks

Plant emerges with heart-shaped variegated leaves. Small delicate blue flower sprays appear.

Keep soil consistently moist. Apply 2-3 inches of mulch around base, leaving crown uncovered. Deadhead spent flowers to encourage longevity.

2

Vegetative Growth (Summer Year 1)

6-10 weeks

Foliage expands significantly. Leaves become larger and variegation becomes more pronounced as temperatures stabilize.

Maintain consistent moisture. In hot climates, ensure adequate afternoon shade. Remove any non-variegated reversions to preserve cultivar appearance.

3

Dormancy (Fall-Winter Year 1-2)

8-16 weeks

Foliage dies back after first frost. Plant retreats below ground level as roots establish.

Leave dried foliage in place for winter protection or cut back to ground level in late fall. Ensure good drainage to prevent crown rot. Apply winter mulch in zone 3.

4

Mature Growth & Flowering (Year 2+)

Ongoing annually

Plant emerges with multiple growth points. Profuse heart-shaped variegated foliage (12-18 inches tall) with abundant airy blue flower sprays in spring.

Deadhead spent flowers for extended bloom. Divide every 3-4 years in spring to rejuvenate. Mulch annually with compost.

5

Senescence (Late Summer-Fall Year 2+)

4-8 weeks

Flowers fade and foliage may decline in intense summer heat. Plant prepares for dormancy.

Cut back dried foliage in late fall. Water deeply before frost. Reduce nitrogen to discourage soft new growth before dormancy.
