Germination & Seedling
10-14 daysTiny seedlings emerge with first true leaves appearing within 7-10 days. Plants develop their characteristic narrow, fine foliage.
Keep soil evenly moist but not soggy. Provide bright light. Thin seedlings to proper spacing once they have 2-3 true leaves. Avoid overwatering to prevent damping off.
Early Vegetative
2-3 weeksPlants form a low, dense mounding shape with increasingly abundant fine, lance-shaped foliage. Growth is rapid and bushy.
Continue regular watering. Pinch back leaders when 2-3 inches tall to encourage bushier growth and more flower buds. Apply dilute fertilizer every 2-3 weeks.
Flowering (Early)
1-2 weeksFirst tiny white flower clusters begin to appear at branch tips. Initial blooms emerge as the plant approaches mature size.
Begin deadheading spent flowers to encourage continuous blooming. Maintain consistent moisture and light feeding schedule. Remove any weak or leggy growth.
Peak Bloom
4-8 weeks (often extends until frost)Plant is covered with dense clusters (umbels) of tiny, fragrant white flowers from top to bottom. Growth is full and well-branched.
Deadhead regularly to maintain continuous flower production. Water deeply but infrequently to encourage deep root development. Cut back hard mid-summer if growth becomes sparse or leggy to rejuvenate.
Decline & End of Season
Variable, until frost or extreme heatAs temperatures cool or grow too hot, flowering slows and plant vigor decreases. Foliage may yellow and blooms become sparse.
In hot climates, provide afternoon shade and increase watering. In cool climates, allow to bloom until frost. Can deadhead and rejuvenate with fertilizer for fall rebloom.

-
Increase humidity by misting foliage in hot weather; spray with strong water stream to dislodge; use miticide or neem oil if severe
-
Use yellow sticky traps; spray with insecticidal soap or neem oil; encourage natural predators like ladybugs and lacewings
-
Ensure excellent drainage; avoid overwatering; remove and destroy severely affected plants; improve air circulation

Harvest Tips
Alyssum is grown for ornamental flowers rather than harvest, but you can cut fresh flower clusters for small arrangements or bouquets. Snip 4-6 inches of stem with flowers. Cutting actually encourages more blooms. For seed saving, allow some flowers to mature and dry on the plant, then collect dried seed pods in late season.
Fun Facts
- 🌱 Despite its common name 'sweet alyssum,' it's actually in the Lobularia genus, not Alyssum. The name comes from Greek words meaning 'absent madness,' as it was historically believed to cure rabies.
- 🌱 Alyssum Wonderland White can self-seed readily in suitable climates, potentially returning year after year. In warmer zones, it may overwinter and bloom again the following season.
- 🌱 The plant produces copious amounts of nectar with a distinctive sweet honey aroma, making it a favorite of bees and butterflies. A single plant can attract dozens of pollinators throughout the day.
