Growth Stages

Seedling/Transplant

2-4 weeks

Small rosettes of thin, green needle-like leaves emerging from soil; minimal branching

Keep soil consistently moist but not waterlogged; provide bright light; protect from strong wind; pinch back lightly to encourage bushiness

Vegetative Growth

4-8 weeks

Rapid horizontal spreading with increasing leaf density; stems beginning to trail outward along ground; foliage dark green to gray-green

Reduce watering frequency as roots establish; thin out weeds carefully to avoid damaging trailing stems; no fertilizer needed; trim lightly after winter to remove dead tissue

Pre-flowering

2-3 weeks

Dense mat formation with visible flower buds appearing at stem tips; foliage lush and compact; plant may show slight reddish tinges in cool weather

Maintain minimal watering; do not fertilize; ensure full sunlight exposure to maximize bloom; remove any dead sections

Flowering

4-8 weeks (typically late spring to early summer)

Profusion of tiny, bright crimson-red flowers clustered on spike-like inflorescences above foliage; blooming covers most of plant; peak ornamental display

Do not deadhead if you want seeds; allow bees and pollinators free access; maintain dry conditions to prevent fungal issues; water only at soil level, not foliage

Post-flowering/Maintenance

Ongoing through fall and winter

Flowers fade to brown seed heads; foliage remains evergreen and decorative; plant ready for light trimming or deadheading if desired

Light shearing after bloom promotes bushier growth next season; remove dead flower heads for tidier appearance; transition to minimal watering; no pruning needed for evergreen maintenance

Harvest Tips

Harvest leaves anytime during the growing season by pinching or cutting off the top 1/3 of stems; best flavor occurs in morning after dew dries. Cut stems just above leaf nodes to encourage bushier growth. For drying, harvest just before flowering when essential oils are most concentrated; bundle and hang upside down in a warm, dark place for 1-2 weeks. Can be harvested lightly even in winter if plant is actively growing.
