Growth Stages

1

Seedling

2-3 weeks

Tiny cotyledons emerge within 5-10 days; first true leaves develop within 1-2 weeks.

Keep soil warm (70-75°F) and consistently moist. Provide bright light. Thin seedlings to prevent crowding.

2

Vegetative Growth

3-4 weeks

Plant develops multiple sets of true leaves and establishes a bushy form with increasingly fragrant foliage.

Pinch off growing tips regularly to encourage branching. Maintain consistent moisture and nutrients. Begin harvesting leaves once plant has 6-8 true leaves.

3

Maturation

Ongoing throughout season

Plant reaches full size and develops dense foliage with strong anise fragrance. Leaf production peaks.

Continue pinching flower buds to extend leaf production. Apply balanced fertilizer every 2-3 weeks. Remove any yellowing leaves.

4

Flowering

6-8 weeks (if allowed to flower)

Small white or pale lavender flowers form in terminal spikes at stem tips. Flowers are edible and fragrant.

Pinch off flower buds to maintain leaf quality and extend harvest season. Allow some flowers if you want seeds or want to attract pollinators.

5

Decline/End of Season

Variable; until frost in cold climates

Plant slows growth in cooler weather or after extended flowering. Leaves may become less tender and aromatic.

In mild climates, cut back severely to rejuvenate. In frost-prone areas, harvest abundantly and dry or preserve leaves before first frost.

Harvest Tips

Begin pinching leaves once plant has 6-8 true leaves. Harvest regularly from the top to encourage bushier growth. Pinch off flower buds to prolong leaf production.

Harvest up to one-third of the plant at a time to maintain vigor.

Fun Facts
