Seedling
6-12 monthsTiny rosettes with silvery, finely divided foliage emerge slowly. Growth is minimal in first season.
Provide consistent moisture without waterlogging. Protect from excessive heat and humidity. Keep in cool conditions if possible.
Establishment
1-2 yearsLow mats of finely textured, gray-green leaves spread slowly across the soil surface.
Ensure excellent drainage to prevent rot. Water moderately during dry spells. Apply thin gravel mulch around base.
Pre-flowering
Spring months (varies by zone)Mature rosette forms, still compact and low-growing, with visible flower buds beginning to develop in late spring.
Maintain good air circulation. Do not overwater. Light feeding with balanced, low-nitrogen fertilizer optional.
Flowering
4-8 weeks (late spring to early summer)Delicate white or pale pink eight-petaled flowers appear on short stems above the silvery foliage, followed by decorative feathery seed heads.
Deadhead spent flowers if you prefer continuous blooms, or leave for ornamental seed heads. Maintain moderate watering during bloom.
Post-flowering
Summer through winterFoliage remains attractive year-round; seed heads persist and add winter interest. Plant enters dormancy in fall.
Allow seed heads to mature for visual appeal and self-seeding. Reduce watering in late fall. No heavy pruning needed.
