Tiny pure white blossoms blanket the ground like new-fallen snow. Dwarf plants are uniform and compact, spreading rapidly. A fragrant choice for well-drained soils in rock gardens and borders. One of the finest cool weather performers. Blooms again and again if trimmed back to remove faded blossoms.

Instructions Chevron Down Chevron Forward
    Growing Instructions:

    Start annual Alyssum seeds indoors 6 weeks before the last frost in your area. Follow the seed depth and spacing guidelines indicated below. Once all danger of frost has passed, seedlings should be hardened off before planting into their growing location. Seedlings should be transplanted according to the plant spacing directions below. Pick a location sheltered from the wind and receives at least 6 hours of sun per day. Regularly monitor your plants and ensure that the soil remains moist, but not soggy while they establish themselves in their new environment.

Suggestions Chevron Down Chevron Forward
Growing Suggestions:
  • Alyssum has the tendency to experience a decrease in flowering activity amidst the scorching heat of summer. However, it quickly rejuvenates and resumes its blooming cycle once the temperatures begin to cool down.
  • Regularly removing spent flowers, known as deadheading will promote continuous blooming and encourage the growth of fresh buds. If you have a large cluster of plants, trimming them by around one-third is a simpler alternative to deadheading.
  • During periods of wet weather, downy mildew can occur as a coating on the leaves that is whitish or white with a slight purple tinge. To prevent this, it is important to plant alyssum in soil that is well-drained and follow the recommended spacing guidelines. This will allow for adequate air circulation around the plants and help mitigate the risk of downy mildew occurrence.
