Seedling
2-4 weeksTiny, delicate seedlings with fine cotyledons and early true leaves. Very fragile and susceptible to damping off.
Provide excellent drainage, minimal water, bright light. Avoid overwatering. Thin seedlings early to prevent competition.
Establishment
6-12 monthsYoung plants develop deeper root systems and accumulate biomass. Foliage remains silvery-green and relatively compact.
Water regularly but allow soil to dry between waterings. Protect from competing vegetation. No fertilizer needed. Mulch lightly with gravel if desired.
Vegetative Growth
1-2 yearsPlant develops branching structure and woody stems. Foliage becomes denser and plant gradually increases in height and width.
Reduce supplemental watering as plant matures. Remove competing weeds. Prune only if necessary to shape. Full sun exposure critical.
Flowering
4-8 weeksSmall, inconspicuous yellow flowers appear in terminal panicles. Flowering occurs in late summer to early fall.
No special care needed. Allow flowers to mature for seed production if desired. Flowers attract pollinators.
Mature/Seed Production
Multiple yearsPlant reaches full size (3-10 feet depending on subspecies and conditions). Seeds mature and are dispersed by wind.
Minimal maintenance needed. Allow natural senescence. Plants decline after 40-50+ years but self-seed if conditions favor germination.
