Growth Stages

Establishment

1 year

Young plant with 3-5 leaves emerging from crown; slow initial growth

Keep soil consistently moist; provide afternoon shade; mulch around base; avoid transplanting for first season

Vegetative Growth

1-2 years

Expanding clump with progressively larger, deeply veined heart-shaped leaves; plant fills out

Water regularly; fertilize in spring with balanced fertilizer; apply organic mulch; monitor for slugs

Pre-Flowering

1 year

Full-sized mature clump with dense foliage; flower buds begin to form in late summer

Continue consistent watering; reduce nitrogen to encourage flowering; deadhead any early flower attempts if desired

Flowering

4-6 weeks (late August through September)

Tall flower spikes (24-30 inches) emerge with fragrant white trumpet-shaped blooms opening in evening

Increase watering during bloom; enjoy evening fragrance; allow some flowers to remain for seed production if desired; deadhead spent flowers

Dormancy

4-5 months (November through March)

Foliage yellows and dies back after frost; plant enters winter rest period

Cut back dead foliage to ground level in fall; apply 2-3 inches of mulch for winter protection; do not fertilize
