Alyssum may be sown directly in the garden after frost or planted as a potted plant.

Sowing Directly in the Garden:

  • Direct sow seeds in average soil in full sun to part shade after danger of heavy frost.
  • Sow seeds 6 inches apart and barely press in; light aids germination.
  • Firm soil lightly and keep evenly moist. 
  • Seedlings will emerge in 8-10 days.

Planting Potted Plants:

  • Select a location in full sun with good rich moist organic soil.
  • Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
  • Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
  • Dig a hole for each plant large enough to amply accommodate the root ball.
  • Set level with the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand leaving a slight depression around the plant to hold water.
  • Water thoroughly, so that a puddle forms in the saucer you have created. This settles the plants in, drives out air pockets and results in good root-to-soil contact.
  • Use the plant tag as a location marker. 
  • Keep soil evenly moist but not wet.
  • Shear plants back by one-half after the first flush of flowers has ended to encourage new buds to form.
  • Plants self-sow so allow some to set seeds.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Remove plants after they are killed by heavy frost in fall to avoid disease issues the following year.
  • Alyssum performs best in areas with relatively cool summers, but can grow anywhere.
  • Alyssum makes a great temporary ground cover and grows nicely with dianthus, violets, and thyme. Plant alyssum between stepping stones or in paving cracks, or grow it in containers. Alyssum also makes a great addition to a butterfly or seaside garden.
  • Alyssum has a sweet fragrance. Plant where you can enjoy this, such as in a window box. Because of the fragrance it will also attract bees, butterflies and many beneficial insects such as lady bugs.

Alyssum, Carpet Of Snow is rated 4.3 out of 5 by 14.
Rated 5 out of 5 by from Even better than the picture! I am extremely happy with my alyssum. I started it indoors from seed and it's been blooming since late May (today is Aug 1.) I planted it in the edge of a 1.5 × 2 × 1.5 ft container to compliment my four o'clocks. As you can see from the pictures, about midsummer it started draping beautifully over the edge of the container, giving the impression of hanging lace. Very easy, attracts pollinators. I am delighted and will definitely plant again.

Rated 4 out of 5 by from So far, so good I bought alyssum seeds a few months ago and sprinkled them in hanging baskets in between my violas, kept them moist, and it took ~one week for germination. Tons of seedlings have popped up already! Can't wait to see these in bloom :)

Rated 5 out of 5 by from Best seed buy ever I've never been one for planting annuals - too fussy and wimpy for me. Except that this alyssum totally beat out the variety from the local garden center. I sprinkled Carpet of Snow seeds in front of my eggplants, weeded a few times, then sat back and relaxed. It is now the best looking little garden I have! Quick to fill in and flower, chickens trample it and it pops right back, edges get mowed but don't turn brown, never quits flowering. I'm buying a packet of these seeds for each of my gardens next year!

Rated 5 out of 5 by from Excellent cover I really didn't know what to expect when I germinated these, but it didn't take long to realize these would be a winner. They grow quickly, and spread fast (be careful what you wish for, it became a little too much cover). My flowers never seem to get as large as the picture, but they are small and delicate and pleasing to look at.

Rated 4 out of 5 by from Are these fast growers? I am interested in starting these indoors to be used in containers to decorate a tables at a bridal shower in April. Can someone tell me if they are fast growing and would bloom in 8 weeks if grown indoors? Thank you for your help!
