Seedling
2-4 weeksTiny green cotyledons emerge and develop true leaves. Plant is fragile and low-growing.
Keep soil lightly moist; provide bright light; protect from frost if sown outdoors in fall. Thin seedlings to proper spacing.
Vegetative Growth
6-10 weeksCompact mound of small, narrow, dark green leaves develops. Plant grows slowly but steadily.
Water moderately; deadhead any early flowers to encourage foliage establishment. Ensure excellent drainage.
Flower Bud Formation
2-3 weeksDense clusters of small buds form at branch tips, creating a crowded appearance.
Reduce nitrogen fertilizer to avoid excessive foliage at expense of flowers. Ensure adequate sunlight for best bud production.
Flowering
4-8 weeks (spring into early summer)Abundant small, white flowers bloom in tight, fragrant clusters, creating a snowy appearance across the mound.
Deadhead spent flower clusters to extend bloom time into early summer. Water if drought occurs. Avoid fertilizing.
Post-Bloom & Dormancy
6-8 monthsFlowers fade; foliage remains evergreen but may look less vibrant. Plant enters semi-dormant state in winter.
Light pruning after bloom maintains compact shape; shear back by one-third to encourage bushier growth next year. Reduce watering in fall/winter.

Cut flower sprays in the morning after dew dries for use in fresh arrangements or drying.
