Establishment
First 4-6 weeksYoung plant develops shallow rhizomatous root system and unfurling heart-shaped leaves with serrated edges
Keep soil consistently moist, provide shelter from wind and hot afternoon sun, apply mulch to retain moisture and regulate soil temperature
Vegetative Growth
2-3 monthsPlant spreads via rhizomes, foliage becomes dense and mounding, bronze-tinged new leaves emerge continuously
Maintain consistent moisture, light feeding in spring with balanced fertilizer, monitor for slugs, thin out dead foliage in late winter if needed
Flowering
4-6 weeks in spring (March-May depending on zone)Airy panicles of small, pale yellow flowers with delicate spurs emerge above foliage, creating an ethereal spring display
Do not deadhead unless plants are overcrowded; flowers attract pollinators, maintain moisture, avoid fertilizing to prevent excessive foliage at expense of blooms
Post-Flowering & Summer Growth
May-AugustFlowers fade to seedpods, foliage becomes the main ornamental feature with deep green color and fine texture
Allow seedheads to dry if self-seeding desired, maintain moisture during hot summers, apply shade cloth in zone 9 to prevent scorching
Dormancy & Fall Transition
September-FebruaryFoliage may take on burgundy or bronze tones in cooler zones; evergreen in warmer zones, foliage persists year-round
In colder zones, do not cut back until late winter; in warm zones, trim old foliage to encourage fresh spring growth, avoid disturbance
