Alyssum, known scientifically as Lobularia maritima, is a versatile and easy-to-grow annual that adds both beauty and utility to your garden. With its decorative blooms and usefulness in companion planting, Alyssum is a valuable addition to any garden landscape.
To grow Alyssum successfully, consider timing and exposure. Start seeds indoors 6-8 weeks before the last frost date or direct sow while some danger of light frost still exists. Alyssum is adaptable and thrives in full sun or partial shade.
When starting seeds, sow them on the surface of the soil and maintain a soil temperature of 12-21°C (55-70°F) under bright lights. The seeds require light to germinate, so do not cover them. Expect sprouting within 5-14 days.
Once seedlings are established, transplant them 20-30cm (8-12 inches) apart after all risk of frost has passed. Watch for slug damage in the early spring and provide freely draining, loamy soil with a pH in the 6.0-7.0 range.
Alyssum is tolerant of dry soil and hot weather, making it suitable for xeriscaping. If watering is abundant, Alyssum responds by growing rapidly. To encourage compact growth and a second bloom, shear plants back by half if growth slows in mid-summer due to heat.
In companion planting, Alyssum is highly attractive to pollinators and beneficial insects. Use it as a cover crop to attract insects, smother weeds, and increase fruit set in vegetable beds. Alyssum also serves as a useful mulch to keep weeds down between rows.
With these essential tips, you can cultivate Alyssum in your garden and enjoy its beauty while enhancing your garden's ecosystem. Start planting today and experience the joys of growing Alyssum in your garden!
