The Edible Parts of Sweet Alyssum

Sweet alyssum, also known by its scientific name Lobularia maritima, is celebrated by gardeners for its dense, low-lying mats of fragrant blooms. Beyond its ornamental appeal, this plant offers a unique dual flavor profile. Both the flowers and the leaves are safe for human consumption, but they offer distinct tastes that can be used differently in cooking.

Sweet Alyssum Flowers

The tiny, clustered blossoms of sweet alyssum are the most popular edible part of the plant due to their delicate appearance and sweet, honey-like fragrance. Available in shades of white, pink, purple, and lavender, these flowers can be used to add both visual appeal and a gentle floral note to dishes. They are perfect as a final flourish on desserts, in cocktails, or scattered over salads.

Sweet Alyssum Leaves

The leaves of sweet alyssum provide a more robust flavor, which is a characteristic of its botanical family, Brassicaceae. They possess a pungent, peppery, or cress-like taste, reminiscent of milder mustard greens. The leaves can be used in savory applications to add a spicy kick, such as in salads, sandwiches, or omelets. For a milder flavor, younger leaves are generally preferred.

Culinary Applications and Recipes

The versatility of sweet alyssum in the kitchen allows for creative uses in both sweet and savory dishes. When harvesting, it's best to pick the flowers and leaves in the morning, when their flavor is at its peak. Remember to wash all plant matter thoroughly before consumption.

Sweet Uses:

Garnish for Desserts: Sprinkle the delicate flowers over cakes, custards, or fruit tarts.
Infused Beverages: Freeze blossoms into ice cubes to add a beautiful and subtle flavor to cocktails and other drinks.
Floral Butter: Whip the flowers into compound butter to spread on bread or pastries.

Savory Applications:

Salad Greens: Mix the peppery leaves and sweet flowers into a garden salad for a complex flavor and visual texture.
Omelets and Soups: Fold the flowers and leaves into omelets or sprinkle them over cold summer soups for a fresh, unexpected flavor.
Meat Garnishes: Use the flowers as a garnish for game meats or roasted dishes.

Sweet Alyssum Nutrition and Health Properties

As a member of the nutrient-dense mustard family, sweet alyssum offers more than just flavor and decoration. The leaves and flowers contain a range of vitamins and minerals.

Vitamins: Rich in vitamins A, C, and E, which support immunity, vision, and skin health.
Minerals: A good source of essential minerals like folate, iron, potassium, and phosphorus, all vital for tissue and cell repair.
Traditional Uses: Historically, sweet alyssum has been used in some herbal remedies as a diuretic to help prevent fluid retention. It was also traditionally used to treat ailments like colds, coughs, and scurvy, due to its vitamin C content.

Sweet Alyssum Safety and Important Distinctions

While sweet alyssum (Lobularia maritima) is safe to eat, it is crucial to follow safety guidelines to avoid any health risks.

Sweet Alyssum vs. Hoary Alyssum

It is vital to distinguish between edible sweet alyssum and toxic Hoary Alyssum (Berteroa incana), a different species in the same family. Hoary alyssum is particularly toxic to grazing livestock and should not be confused with sweet alyssum.

Other Safety Considerations

Pesticide-Free Source: Always consume sweet alyssum from a known, reliable source, preferably grown from seed in your own garden without chemical pesticides or fertilizers. Plants from nurseries may have been treated with chemicals not safe for ingestion.
Moderation is Key: Like other Brassicas, sweet alyssum contains goitrogenic compounds that can interfere with thyroid activity if consumed in very large quantities. Moderate consumption is safe, but excessive amounts should be avoided, especially by those with thyroid issues.
Potential for Upset: Overeating any plant can cause mild gastrointestinal upset, so start with small amounts to assess your body's reaction.
