- Types of Sweet Alyssum Flowers
The word “alyssum” comes from the Greek word “lyssa,” which means “rage” or “bitterness.” It’s quite a contrasting name when you think about it, as this flower looks pretty and full of life. In the past, it was used as an antidote to treat diseases like rabies and was effective in calming angry souls. However, it is no longer used for these purposes and thus, has no further use in medical terms.
Alyssum belongs to the “yellow mustard” family. Its botanical name is “Lobularia maritima” (Lobularia, its genus name, means small pod, and Maritima refers to its natural coastal habitat), and its common name is “sweet alyssum.” The order it belongs to is “Brassicales,” and it is part of the Brassicaceae family.
The plant grows once a year and usually has a life span of more than two years. It exists as small shrubs and grows about 5-30 cm long and 20-30 cm wide. It has a very vast branch system with little flowers on each of its branches. The leaves are 1-4 mm long and 3-5 mm broad. They are alternate, sessile, quite bushy, oval, and with a complete margin.
The flowers are very small in diameter, about 5 mm, and have a sharp and sweet-smelling aroma. They are available in various colors, such as lilac, rose-red, violet, and pink. The six stamens have yellow anthers. Lobularia maritima blooms all throughout its growing season, or year-round in regions liberated from ice. They’re pollinated by bugs (entomophily). The seedpods are fuzzy and oval, with each containing 2 seeds. The propagation of these seeds is usually done by the breeze (anemochory).
They Attract pollinators
Due to their attractive colors, these flowers are used to attract pollinators and beneficial insects such as butterflies, hoverflies, ladybirds, hummingbirds, etc. Its strong, sweet smell attracts hoverflies towards it for nectar. One of the benefits of working with insectary plants is that new flowers start to sprout as others wither away, so the insects consistently have a trustworthy supply of nectar and pollen. This ensures that the offspring of these insects are well-fed, which will ultimately result in better protection for the gardens.
These insects prove to be useful in pollination. Bees, butterflies, moths, flies, and even certain beetles can carry pollen from flower to flower. Insects transfer pollen to the areas of the flower that need it for self-pollinating plants. Some insects can carry long pollen over long distances, which can assist in the distribution of genetic diversity within a population of plants. During this process, the insect picks up the pollen on its body and rubs it off on another flower, thus helps spread the pollen from one flower to another.
Uses in Medicine
It is used for various medicinal purposes. In Spain, this plant is used as an antiscorbutic and a diuretic. It was formerly used to treat rabies, colds, and abdominal pain. According to popular belief, it is also effective in the treatment of gonorrhea. Along with all of these amazing uses, it can be used to treat scurvy and to stop the bleeding of gums, helps in the retention of fluids, and can be used in the treatment of kidney diseases and for relief from urine pain.
