Growth Stages

1

Seedling/Establishment

3-6 months

Young plants develop small, aromatic green leaves; growth is slow and steady

Water regularly the first season to establish deep root system. Provide afternoon shade in hottest climates. Do not overwater or fertilize heavily.

2

Vegetative Growth

6-18 months

Plant grows taller and wider, developing dense, bushy foliage with dark green, finely textured leaves

Minimal water after first year. Prune lightly to shape if desired. Avoid nitrogen-rich fertilizers which promote tender growth susceptible to disease.

3

Flowering

April-June (spring/early summer)

Small purple, lavender, or white flowers bloom in tight clusters along stems; flowers attract bees and hummingbirds

Deadheading is optional; allow some flowers to remain for seed production and wildlife. Provide full sun for best flowering.

4

Seed Production & Maturity

Ongoing (perennial)

Flowers fade and develop small seed capsules; plant reaches full mature size and shape

Allow seeds to develop naturally for self-seeding and bird food. Mature plants need minimal intervention.

5

Dormancy/Winter

2-4 months (minimal in zone 9-10)

Growth slows significantly; foliage may appear slightly reduced in cool-winter zones but remains evergreen

Withhold supplemental water. Avoid pruning in late fall; wait until spring. Mulch lightly in zone 8b for frost protection.

Harvest Tips

Harvest fresh leaves year-round for tea, cooking, or dried use. Pinch or cut stems in the morning after dew dries. For drying, cut stems, hang upside-down in a warm, shaded location for 1-2 weeks. Harvest flowers when fully open for herbal use. Mature plants tolerate moderate harvesting without harm.
