Royal Carpet Alyssum Seeds For Planting (Lobularia maritima)

Sowing The Seed

Alyssum flowers are best established directly outdoors, when the weather is warm and all danger of frost has passed. Begin by clearing your sowing area of all unwanted plant life. Turn the dirt, or replace it with fresh soil. Scatter your Alyssum seeds (in groups of 4) to the surface of the soil, lightly covering the seed with 1/16” of topsoil.

Alyssum seeds can also be started indoors, in peat pots, 6 to 8 weeks prior to the last frost. Sow 3 to 4 seeds per pot, at a shallow depth of 1/16” under topsoil. Transplant when all danger of frost has passed, later in the season.

Growing Conditions

Alyssum seeds & plants aren’t too picky on growing conditions. An area of full sunlight is recommended, as well as temperatures of at least 65F to 70F. The soil doesn’t need to be rich in organic matter, but it will need to be well drained for successful growth. It is best to add a light compost to any areas that contain hard, compact soil to improve drainage. Water daily with a moderate moisture setting until germination occurs.

Germination & Growth

Your Alyssum seeds will begin to sprout within 7 to 21 days after sowing. The plants will grow to a short height of only 2 to 4 inches tall and can be spaced roughly 12 to 18 inches apart from one another. Royal Carpet produces lovely clusters of violet flowers. Because of its short height, it is perfect as a ground cover and is also great in rock gardens as well.
