Germination & Seedling
2-4 weeksTiny seedlings emerge with fine cotyledons and initial true leaves. Growth is slow in first weeks.
Keep soil lightly moist but well-draining during germination. Provide bright light. Cold stratification (2-4 weeks) may improve germination rates.
Vegetative Growth
4-8 weeksLow rosette forms with fine, wiry stems and needle-like foliage. Plant remains compact and near ground level.
Water sparingly, only when soil is dry. Ensure excellent drainage. Begin reducing water as plant matures. Full sun is critical.
Flowering
6-10 weeks (June-August typically)Delicate spire-like flower clusters emerge on thin stems in shades of pink to rose. Flowers are tiny, densely clustered on elongated inflorescences.
Continue dry conditions; do not fertilize. Support stems with small stakes if grown in containers. Deadhead spent flowers to extend blooming.
Seed Development & Dormancy
Ongoing into fall and winterFlowers fade and develop papery, three-winged seed pods. Foliage may persist or die back depending on climate.
Allow seed pods to mature for self-seeding. In colder zones, provide winter protection with sandy mulch. Reduce water to near zero.
Winter Dormancy (Zones 5-6)
December-MarchPlant may die back completely or remain semi-evergreen depending on zone and conditions.
Provide protection in zones 5-6 with a light mulch of gravel or sand (not organic matter, which promotes rot). Ensure excellent drainage before winter.

Common Pests
-
Prevent via excellent drainage and minimal watering. Remove affected plants. Do not amend soil with water-retentive organics.
-
Spray with water or insecticidal soap if infestations occur. Usually not a major problem in dry conditions.
-
Increase humidity around plant slightly or spray with neem oil. More common in very dry, hot conditions.
