Seedling
3-4 weeksTiny, delicate needle-like leaves emerging from soil; very slow initial growth
Maintain consistent light moisture (not wet); provide bright light; ensure excellent drainage; be patient—germination is slow (2-4 weeks) and growth is gradual
Vegetative Growth
2-3 monthsPlant develops multiple stems with increasingly dense needle foliage; horizontal growth pattern becomes apparent
Water sparingly once established; ensure full sun; no fertilizer needed if planted in decent soil; prune tips lightly to encourage branching and spreading
Flowering
6-8 weeks or longer (spring and fall mainly, can flower year-round in warm climates)Small, delicate flowers appear along stems in clusters; colors range from blue, purple, pink, to white depending on variety
Continue regular (but sparse) watering; full sun encourages blooming; flowers attract pollinators; no deadheading necessary but removing spent flowers tidies appearance
Established Maturity
Indefinite (perennial)Plant forms a dense, spreading mat or mound; fully trailing or cascading habit; continuous foliage and periodic blooming
Minimal care; water only during dry spells; drought-tolerant once rooted; occasional light pruning maintains shape; remove any dead wood; no fertilizer needed

Harvest Tips
Pinch or snip fresh leaves and tender stems as needed year-round once plant is established (after 3-4 months); harvest in morning after dew dries for best flavor and aroma. For drying, cut sprigs just before flowering, tie in bundles, and hang in warm, well-ventilated space. Avoid harvesting more than 1/3 of plant at once. Can be harvested even in winter in mild climates.
