Alyssum Growing the Colorful Carpet Flower

Alyssum plants have been cultivated for centuries. In Spain, in the 1500s, a sweet alyssum was discovered that bordered edible gardens or grew wild on Mediterranean beaches. Alyssum flowers are not only beautiful, but also attract a lot of useful pests that will help you grow a garden.

The short-lived Alissum has been cultivated long enough to produce heat- and drought-resistant varieties. These small flowers are sown singly and can be biennial in temperate climates. As alissum does not grow very tall, it is a great way to delimit a garden of a few square feet or to create a barrier between the rows.

Alyssum is a powerful propagator thanks to its small flowers. There are many varieties of different shades and colors. On the garden plots of alyssum lavender, pink, yellow and white flowers grow. Plant white snow crystals or try a pink variety that blooms in spring and autumn, such as the Royal Carpet. Whether you choose snow-white or pink, you don’t need to go far; there are seedlings in every nursery.

All about Sweet alyssum

Sweet alyssum was originally grown in southern Europe, mainly in Spain. The first mentions of sweet alyssum date back to the 1500s. The main species of alyssum, Lobularia maritima, was hybridized and bred over a period of 1800 ans.Il is not surprising that these white flowers are still used in gardens to grow edible plants, as they attract beneficial host insects. They are also relatively unpretentious in care.

Alyssum is known as a carpet flower due to its low, wide size and its use as a litter. The root of the scientific name Lobularia maritima comes from the Latin words meaning “seed pod” and “coast”. The plant has a genus synonym called alyssum. Some alyssums are annuals. Some are short-lived and persistent. In optimal climatic zones, this plant is a short biennial.

Alyssum plants, belonging to the Brassicaceae or mustard family, have simple gray-green leaves arranged alternately on the central stem. The leaves cover the trichomes. The small symmetrical fragrant flowers of alyssum have four petals and grow in clusters. The color of the flowers varies from sapphire to purple or from red to pink. The most common alyssum plants have white flowers. If you want to grow an old alyssum, pay attention to the white variety.

The sweet plants of alyssum are small and herbaceous. They bloom from summer to autumn. When the flowers bloom and fall, seeds called silicones are formed. With the approach of winter, the pods dry up and open, scattering the seeds on the ground. Then, in early spring, the sweet alyssum begins to bloom again.

Since alyssums are no more than 12 inches tall and 12 inches wide, they are often used to delimit gardens and individual areas. This border is used for design purposes or to attract beneficial insects to an edible garden. They also attract host pollinators, which stimulates pollination for food production.

Some varieties of sweet alyssum reproduce well and may need to be stored in containers. Contact your local agricultural consulting office to determine the best varieties for your area. If you are not sure which variety you have harvested from the nearest nursery, grow them in hanging baskets or containers. However, there are many species adapted to different regions of the world, so it should not be difficult to find plants.

Gentle care for alyssum

Alyssums are easy to care for, and many modern varieties are resistant to drought, heat and frost. Choose the appropriate variety for your region. Let’s discuss the basic requirements for alyssum.

Lighting and temperature

Sweet alyssum plants need full sun in the penumbra. Let the sweet alyssum stay in the sun for at least 6-8 hours. Alyssums are resistant to USDA zones 5 to 9 and can withstand low temperatures of up to 20 degrees Fahrenheit. Alissum prefers cooler conditions and usually grows poorly at temperatures above 85 degrees. There are frost-resistant varieties that tolerate the cold well, and some in hot weather.

In order for the alyssum to overwinter, cut it for the winter, cover it with a matte cloth or place the containers inside. In non-heat-resistant varieties in summer, a shading cloth should be present.

Water and humidity

Alyssum Sweet plants like moist soil with at least 1 to 2 inches of watering per week. Avoid overwatering the alyssum, as it is prone to root and crown rot. If you water the sweet alyssum, do it in the morning until the soil warms up. In hot weather, water alyssum with cool water in the morning and at dusk. Dusk offers the best water protection, as your plants have more time to absorb moisture before the sun evaporates.

Drip irrigation protects the leaves and flowers of alyssum damaged by air watering. Submersible tubes are also suitable. Since sweet alyssum is a drought-tolerant plant, do not water it too much. Maintain soil moisture, but don’t water it too much. If it rains regularly for a while, do not water.


Sweet alyssum prefers slightly acidic, loamy and well-drained soil. It easily takes root in containers of potted soil. In the soil, Sweet alyssum likes a simple and slightly modified garden soil, but it will work great on poor soil too if that’s all you have to work with. Alyssum prefers a pH of 6.0 to 7.0, so keep the soil on this bank.


Lobularia primorea, which grows in the ground, does not require fertilizers on prepared soils, but it is better to use slow-release granular fertilizers when planting. On poor soils and in containers, apply water-soluble fertilizers once a month. Apply fertilizer for the soil cover every year. To do this, use a balanced 20-20-20 formula.


The flowers of sweet alyssum benefit from a small size. To encourage prolonged flowering, pinch the first flower(s). This will give you the start you need to attract beneficial insects to your edible garden.

Once the flowers of alyssum (Lobularia maritima) bloom and fall, cut them to get more flowers. Some varieties of carpet flowers bloom very quickly and bloom several times in one season. If you have a lot of pretty alyssum flowers, cut them to a third of their size. Then the alyssum flowers will return to your garden stronger next season.

Sweet alissum pleases with a stable harvest. Herbaceous plants that do not interact with humans do not have a long life cycle. Visit your garden regularly to chat with this plant and treat yourself to free greens for salad.

Alyssum plants like to be pruned and mulched in anticipation of snow and frost. The mulch retains heat and protects the alyssum roots from snow and ice from the first to the last frost. Although this is not necessary, as they will return in the spring, you can cut them and compost them just before the first frosts. This also applies to soil plants and container plants.
