I've been sowing it for 3 years now, it self-seeds, we easily collect the seeds, it's gorgeous, it grows into beautiful long stems of 25-30cm (10-12in), and some stems even resist frost! You just need to cut the straw it forms during winter.

Description

Lobularia maritima or Scented Alyssum Crystallina, also known as Sweet Alyssum, is an annual groundcover with very attractive flowering. Indeed, its multiple small flowers of pure white colour appear as early as June and continue until October. They are abundant, fragrant, and attract many insects.

This Alyssum has many features: its compact habit forms a ball of flowers that allows it to cover the edges of flower beds, but also to blend with hanging annuals and in containers. It easily fits in with plants that grow a little more vertically, thus filling their base. It is an annual that prefers a sunny exposure and adapts to various soils. This Sweet Alyssum will easily find its place everywhere: in the garden, in rock gardens, on walls, and in containers to add a touch of volume. You can sow it directly in situ, by broadcasting the seeds, as soon as the temperatures are mild, or start it undercover to then use it in all your pot or container compositions.

Its brilliant white colour will provide special lighting to certain areas of the garden. You can create patches of light by grouping the plants together, or even highlight the edges of flower beds by assembling them in a ribbon. It will also naturally fit in with other companions, regardless of their colour.

The Alyssum Crystallina is therefore an essential annual: it fits into all compositions, is very floriferous, and requires no maintenance.

Planting and care

Sweet Alyssum Crystallina is preferably sown under shelter in a seed tray from March onwards. If frost is still persistent in your region, wait until April as the seeds will prefer a temperature close to 18°C (64.4°F). Just cover the seeds with a thin layer of substrate that you will keep slightly moist. The seeds will germinate in about fifteen days. When the seedlings are large enough to be moved, you can separate them and place them in planters if the frost period is not over and keep them warm. Otherwise, you can plant them directly in the ground. You can also sow them directly in the soil from April, if your climate is mild, or in May if you still fear the cold. Once they have germinated, you can thin them out by removing any excess plants if necessary.
