Lobularia maritima ‘Royal Carpet.’ Grow for a low-growing carpet of lovely, mauve, scented flowers that stays only 5-10cm (2-4″) tall. Sow Dwarf Purple Alyssum seeds around the edge of veggie beds to improve pollination, or sprinkle them between cracks and paving stones to fill in with a moss-like appearance, followed by scores of tiny purple flowers. This Alyssum works well in containers and window boxes. It has a spreading habit, so is useful as a plant to fill in spaces between others. It is attractive to both pollinators and beneficial insects, making it generally useful to have in the garden.

Let us show you how to grow Alyssum from seed using these tried and true techniques. Alyssum is an easy-to-grow annual that is both decorative and useful. It plays a key role in Companion Planting and can be used as a cover crop to attract insects, smother weeds, and increase fruit set in vegetable beds.

Annual plants also known as Sweet Alyssum.

Lobularia maritima
Family: Brassicaceae


Season & Zone
Exposure: Full sun or partial shade.
Zone: 3-10, not winter hardy

Start indoors 6-8 weeks before the last frost, around the beginning of March to early April here on the coast. Transplant out after all danger of frost has passed. Or, direct sow while some danger of light frost still exists. It’s very easy, either way.

Sow seeds on the surface of the soil. If starting indoors, use a sterilized seed starting mix and maintain a soil temperature of 12-21°F (55-70°F) under bright lights. Seeds require light to germinate, so do not cover them. They should sprout in 5-14 days.

Transplant 20-30cm (8-12″) apart once all risk of frost has passed. Watch for slug damage in the early spring. Alyssum prefers a moist loamy soil with a pH in the 6.0-7.0 range, but it’s adaptable. It is tolerant of dry soil, and can be used for xeriscaping. If growth slows in mid-summer due to heat, shear plants back by half to encourage compact growth and a second bloom. May self sow.

Companion Planting
Alyssum is very attractive to pollinators, and useful as a mulch to keep weeds down between rows.

    Very good indoors germination rate. Absolutely all I planted came out and they are growing super strong under lights and even braving some disturbances such as early mildew.

    I just wanted to provide an update: The flowers make lovely clumps that really fill out the space and self sow. They keep on producing and, boy, this smells so good! I have tons of bees going at it and my garden is absolutely stunning with those. I saw a similar effect with the Snow Cloth as well.
