History / Discovery / Cultivator
Sweet Alyssum, scientifically known as Lobularia maritima, boasts a history deeply intertwined with the sun-drenched landscapes of the Mediterranean. Its origins trace back to the coastal regions surrounding the Mediterranean Sea, as well as the Canary Islands, where it thrives in sandy, well-drained soils close to the ocean’s edge. The plant’s early appeal likely stemmed from its profuse flowering, sweet fragrance, and relatively easy cultivation in these native environments.
While the exact date and discoverer of Sweet Alyssum remain somewhat obscured in historical records, its presence has been noted in botanical literature for centuries. Early botanists and plant collectors, captivated by its beauty and fragrance, recognized its potential for ornamental use. The plant’s journey from its native habitat to gardens around the world began with these initial observations and collections.
Cultivation of Sweet Alyssum outside its native range probably started in the 17th or 18th century, as European gardens embraced the exotic flora from various corners of the globe. Its compact growth habit, continuous blooming, and delightful fragrance made it a popular choice for borders, rock gardens, and containers. The plant’s adaptability to different climates and its ability to attract pollinators further contributed to its widespread adoption.
Over time, various cultivars of Sweet Alyssum have been developed, each with unique characteristics and aesthetic appeal. Plant breeders focused on improving traits such as flower color, plant size, and heat tolerance. ‘Snowdrift’, ‘Royal Carpet’, and ‘Easter Bonnet’ are just a few examples of the many cultivars that have been introduced, offering gardeners a diverse range of options to choose from. These cultivars often exhibit variations in flower color, ranging from pure white to shades of pink, purple, and lavender. Plant size can also vary, with some cultivars being more compact and others more spreading.
The popularization of Sweet Alyssum can be attributed to several factors, including its easy cultivation, continuous blooming, and sweet fragrance. Gardeners appreciate its versatility and its ability to thrive in a variety of conditions. The plant’s relatively low maintenance requirements also make it an attractive option for both novice and experienced gardeners. In addition, Sweet Alyssum’s ability to attract beneficial insects, such as bees and butterflies, has further contributed to its popularity.
Today, Sweet Alyssum remains a beloved garden plant, gracing gardens and containers around the world with its beauty and fragrance. Its long history of cultivation and its continued popularity are a testament to its enduring appeal. From its humble origins in the Mediterranean region to its widespread cultivation as an ornamental plant, Sweet Alyssum has earned its place as a garden classic. Its sweet fragrance, profuse flowering, and easy cultivation make it a welcome addition to any garden or landscape. Furthermore, it continues to evolve through breeding programs, offering gardeners even more options to choose from and ensuring its continued presence in gardens for years to come.

Botanical Insights
Adaptations
Sweet Alyssum’s adaptations are well-suited for its Mediterranean origins. Its compact growth habit and relatively small size allow it to thrive in exposed, coastal environments where wind and salt spray can be challenging. The plant’s ability to tolerate drought conditions is also an important adaptation, as rainfall in the Mediterranean region can be limited during the summer months. Furthermore, its profuse flowering and sweet fragrance attract a wide range of pollinators, ensuring successful reproduction.
The plant’s ability to self-seed readily is another important adaptation, allowing it to quickly colonize new areas and persist in disturbed habitats. Its tolerance of poor soil conditions also contributes to its adaptability, allowing it to thrive in areas where other plants may struggle. Finally, its relatively short lifespan can be seen as an adaptation, allowing it to quickly take advantage of favorable conditions and complete its life cycle before conditions become unfavorable.
Propagation Methods
Sweet Alyssum is most commonly propagated by seed. Seeds can be sown directly into the garden in early spring or started indoors 6-8 weeks before the last expected frost. Cuttings can also be taken in spring or summer, although this method is less common. To propagate from cuttings, take a 4-6 inch stem cutting from a healthy plant, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist until it roots.
Toxicology
Sweet Alyssum is generally considered non-toxic to humans and pets. According to the ASPCA, it is not listed as a toxic plant. However, as with any plant, it is always best to supervise children and pets around Sweet Alyssum and to prevent them from ingesting large quantities of the plant. While it’s not toxic, eating a lot could potentially cause mild gastrointestinal upset.
