Collection: Alyssum Seeds (Heirloom)

The best heirloom alyssum to grow at home

The genus Lobularia gets its name from a Greek word that means "little pod," alluding to the shape of the fruits. The name maritima refers to the species' favored coastal environment. Sweet alyssum is its popular name, but it is often known as plain alyssum. For many years, gardeners have relied on alyssum as a go-to plant. The low-maintenance nature, drought tolerance, and beautifully fragrant blooms that will quickly cover grounds and borders with a burst of color are just a few of the reasons for its popularity.

Planting information for heirloom alyssum

Heirlooom alyssum grows three to nine inches tall and produces a continuous abundance of sweet-smelling flowers from spring through mid-summer, making it an excellent container flower. Our heirloom alyssum seeds can be planted directly outside after the last frost of the spring season, or they can be started indoors five to six weeks before the last frost and then transplanted outside. Ground cover, borders, and even the cracks of a rock garden are all ideal places for alyssum. Many other plants would find slopes and rocky settings unfriendly, yet Alyssum thrives. Choose an area that gets plenty of sun if at all possible six to eight hours a day).

Best conditions for growing heirloom alyssum

Alyssum can withstand some shade (four to six hours a day). Look for a site with acidic, well-draining soil. Soils that are rocky or sandy are permitted. Once you've chosen a location, lightly push the seeds into the soil's top layer, no more than 1/8th of an inch deep. Make sure the seeds aren't buried because they need to be exposed to sunshine to germinate properly. Keep in mind that alyssum is a plant that spreads.

How to care for heirloom alyssum plants

Once your plants have established themselves, you'll discover that alyssum to bed is a low-maintenance addition to your garden. Simply water the roots deeply but sparingly, allowing them to dry out between waterings. This is especially true when the tree is planted in a partially shaded area. Root rot is encouraged by consistently moist soil, so avoid overwatering. Throughout the growing season, some mild trimming and deadheading can be done to encourage more blooms. Even if you don't deadhead, you'll have a seemingly endless parade of flowers to admire. Despite the fact that they are classified as annuals, alyssum will self-sow and return year after year, adding vibrant hues to any garden or container.
