Growth Stages

1

Germination

7-14 days

Tiny seedlings emerge with cotyledons; very delicate and slow-growing initially

Keep soil consistently moist but not waterlogged. Maintain 65-75°F. Provide bright light immediately upon sprouting.

2

Seedling

2-3 weeks

First true leaves appear; plant develops narrow, linear foliage characteristic of alyssum

Thin seedlings to proper spacing. Provide bright indirect light. Begin fertilizing weekly with diluted liquid fertilizer once true leaves appear.

3

Vegetative Growth

3-4 weeks

Plant forms dense, compact mound of fine foliage; bushy branching begins

Water regularly but allow soil to dry slightly between waterings. Pinch growing tips if desired to encourage bushier growth. Apply balanced fertilizer every 2-3 weeks.

4

Flowering

8-12 weeks or until frost

Dense clusters of tiny, fragrant flowers bloom in pink, purple, or white; continuous blooming throughout season

Deadhead spent flowers to encourage continuous blooming, though not essential. Reduce nitrogen fertilizer to promote more flowers. Water during dry spells. Fragrance intensifies in warm weather.

5

Decline/Senescence

Variable; until killing frost

Plant may become leggy and less floriferous in peak heat or after first frost

Cut back by half in mid-summer to rejuvenate and promote fresh blooming. In mild climates, plant often reseeds for next season. Annual plants decline after frost.

Harvest Tips

Alyssum is primarily ornamental and not harvested in the traditional sense. Cut fresh clusters of flowers for small bouquets and arrangements.

Allow some flowers to mature and dry on the plant if you want it to self-seed for the following year.

Fun Facts

  • 🌱 Easter Bonnet Alyssum blooms prolifically without deadheading, though removing spent flowers extends the bloom season even further—some gardeners report continuous blooms for 4-5 months.
  • 🌱 Sweet alyssum's fragrance is strongest in warm weather and early morning; a single plant can perfume an entire garden area on a calm, warm evening.
  • 🌱 The name 'maritima' refers to the plant's original Mediterranean coastal habitat, where it grows in rocky, salt-spray-exposed areas, making it naturally drought and salt-tolerant.
