Germination & Seedling
3-6 weeksSeeds germinate in 10-20 days under warm conditions; seedlings develop fine, feathery cotyledons and delicate true leaves
Keep soil barely moist; provide bright light; avoid fungal issues with good air circulation. Some species benefit from scarification or stratification.
Juvenile Growth
6-12 monthsPlant develops fine-textured foliage and compact branching structure; growth is relatively slow in first year
Water sparingly; provide full sun; avoid excessive fertilizer. Thin or prune lightly to encourage bushiness if desired.
Pre-flowering
6-12 monthsPlant reaches near-mature size and begins to develop flower buds; foliage becomes fuller and more established
Reduce watering further as plant establishes; no fertilizer needed. Ensure full sun exposure for flower initiation.
Flowering
4-8 months (spring through fall, depending on species)Delicate flowers appear in dense spikes or clusters, typically in shades of purple, pink, yellow, or white; flowers are often fragrant
Maintain dry conditions; deadhead spent blooms to extend flowering if desired. No supplemental water needed except in severe drought.
Seed Production & Dormancy
Variable; continues through winter in warm climatesFlowers fade and develop small seed pods; plant may defoliate partially or fully in winter or during extreme drought stress
Leave seed pods if wildlife and self-seeding are desired. Minimal care needed; no watering or fertilizing in dormant period.
