Alyssum can tolerate temperatures as low as 28 degrees Fahrenheit, and the plants will do well in a temperature range of 50–60 degrees Fahrenheit.
Cold, wet weather – Cold, wet weather can induce fungal disease and subsequent root and crown rot. Poor Irrigation before establishment – Newly planted annuals need even moisture and good care while they are becoming established. If they are not properly watered from the start, they can dry out and die quickly.
- Keep sweet alyssum in full sun. The plants do best in full sun but can also survive in partial shade. ...
- Water sweet alyssum sparingly. Give the plants one inch of water per week and make sure the soil dries out completely between waterings. ...
- Deadhead the plants to encourage growth.
Almost any vegetable, flower, herb, shrub, or small tree can grow successfully in a container. Dwarf and compact cultivars are best, especially for smaller pots. Select plants to suit the climate and the amount of sun or shade the container will receive.
Sweet alyssum, Lobularia maritima, is a common annual flower plant. Lobularia maritima is a mat-forming annual or short-lived perennial native to the Mediterranean, Canary Islands and Azores, where it grows along the coast in rocky, sunny areas.
Both alyssum and creeping phlox are low-growing, flowering plants. The common name, “alyssum,” however, can refer to more than one kind of plant. Sweet alyssum, usually grown as an annual, has the botanical name Lobularia maritimum. It belongs to the Brassicaceae plant family.
Extremely heat tolerant, it is noted for its spreading, mounding and cascading habit.
Alyssum is non-toxic to dogs and non-toxic to cats.
Can sweet alyssum survive a freeze?
Alyssum seedlings can tolerate light frost, but plants are often killed by freezing temperatures.
Annual-grown Alyssum does not require any winter protection. The plants will die back with the first frost of the fall. They can then be composted or thrown away. The cooler fall weather will spur the plants into another flush of vigorous growth in the zones where Alyssum is perennial.
Glyphosate, a non-selective herbicide, will also control hoary alyssum (Jacobs and Mangold, 2008).
Water. Provide your sweet alyssum plants with at least an inch of water every week, watering them more frequently during hot weather days or dry spells. The water should drain well.
In cold-winter areas, plant after all danger of frost has passed in the spring. Most varieties will bloom through fall. In mild winter areas, plant during the fall and winter for blooms until it gets hot in the summer.
Sweet alyssum plants require full sun to partial shade. Give sweet alyssum at least 6 to 8 hours of sunlight. Alyssums are hardy to USDA zones 5 through 9 and handle cold temperatures down to 20 degrees Fahrenheit. Alyssum prefers cooler conditions and generally doesn't do well starting at 85 degrees.
Alyssum will grow leggy if it's given inadequate sunlight, or if you don't cut it back. Photo by Allison Sidhu. It prefers to be placed in an area with well-draining soil, but only needs extra watering the hottest and most dry periods of the summer.
Flowers can last for about a week or two in a vase if cared for properly. Here are some tips to make your flowers last longer in a vase: Choose long vases for the light and delicate flowers, and put massive bouquets in small wide containers. Trim the flowers short.
Alyssum flowers grow in mounds that are three to six inches tall, and some varieties can spread up to 24 inches, producing gorgeous mounds of color. Thankfully delicate nature is such that the alyssum plant is not one to choke out its neighbors by overcrowding them.
Sweet alyssum flowers best with at least six hours of full sun, but can tolerate partial shade. In warmer climates, plants perform best with protection from hot afternoon sun.
Where is the best place to plant alyssum?
Where to grow alyssum. As long as the ground is free-draining and doesn't remain damp, alyssum will grow in any reasonable garden soil. Full sun gives the best flowers although light shade still gives good results. Grow at border edges, in pots and window boxes, on banks, rockeries, or at the edges of vegetable beds.
Sweet alyssum flowers attract beneficial insects which then move on to other plants in the vicinity. Having sweet alyssum as a food source could help to enlarge beneficial insect populations, providing more opportunity for these beneficial insects to attack pests. A classic example is aphid management using ladybugs.
Specifically, sweet alyssum is known to attract three main categories of beneficial predator insects (those that eat pest insects in the garden): 1) Minute pirate bugs (who eat aphids, thrips, mites, psyllids, and insect eggs), 2) Parasitic wasps (who lay eggs in aphids, beetles, flies, moths, sawflies, mealy bugs, and ...
Alyssum is not a plant that takes to dividing well. The best way to propagate it is to allow the plants to self-seed or save the seed so that the plant can be started indoors for the following spring. Alyssum will seed heavily in most growing zones.
This invasive stink bug is now established throughout Southern California, and if alyssum is growing in your yard, there is a good chance the bug has infested it. The Bagrada bug, also called painted bug, is a small, colorful insect.
In this case, the Swiss chard taproot can extend up to 6 feet deep, while sweet alyssum roots are shallow and fibrous. The roots of the two plants are active at different levels of the soil, and are therefore not in competition.
Cool-season bloomers larkspur (Consolida), sweet William (Dianthus), snapdragon (Antirrhinum majus), sweet alyssum (Lobularia maritima) and lobelia (Lobelia erinus) all are reported to be deer resistant annuals.
This enjoyable bloom boasts a fragrant scent and a serene, spiritual energy, which is said to provide an emotional balance in the home or office. Asides from symbolising beauty, the Sweet Alyssum is said to protect an individual from heated encounters.
Will alyssum come back? The answer is yes in most garden zones. Once the tiny flowers are spent, they will release seeds right back in to the ground. The easiest way to assure they reseed themselves is to do nothing when they die back.
A: A few so-called annuals go dormant over winter and survive in an unheated garage. I've done that myself with 'Black and Blue' salvia, geraniums and agapanthus. I keep the plants in their pots, move the pots into the garage and cut back the foliage once it browns.
What do you do with potted annuals in the winter?
Many “annuals” can be brought inside, even tender plants that need a winter dormancy period. These should ideally come indoors before nighttime temperatures dip below 45°F (7°C). As fall approaches and night temperatures reach about 50°F (10°C), start bringing the plants inside for the winter.

Some growers use sweet alyssum to promote biological defenses but a new dangerous agriculture pest to California is also showing to be attracted to the plant. Sweet alyssum has been used by producers for a long time to attract natural defenses for agriculture pests.
The Bagrada bug, Bagrada hilaris, also called the painted bug, is a stink bug that attacks various vegetable crops, weedy mustards and several ornamental plants within the mustard family (Brassicaceae) such as sweet alyssum, stock, and candytuft.
Your alyssum plant may wilt with too much water or too little. Keep in mind that an alyssum plant that is wilting does not necessarily always need water. Sometimes alyssum plants wilt when they have too much water. Always check the soil dryness to determine if you should give the alyssum plant some water.
Pots absorb heat, which can stress plant roots, and the soil in them dries out much faster than soil in the ground. Container plants generally need to be watered daily. During really hot weather, you may need to even water twice a day, especially smaller containers.
Cut back the top of the plants by one-half of their height, using small shears. Beneath the leggy stems lusher, greener foliage grows. Pruning back to the green foliage encourages more flowering.
Alyssum Growing Tips
Keep alyssum well-watered during hot, dry weather. It has few pests and diseases. In mid summer to stimulate more growth and flowering shear your alyssum plants by 1/3rd of their height. Fertilize afterward with a balanced product and water and they will regrow for a late summer flower show.
Alyssum needs deadheading through the summer months and shearing back done once or twice during the primary growing season. Deadheading will extend flowering and delay seed ripening. Alyssum can ripen seed at a fast rate all season long, and deadheading will help to curb excessive self-seeding.
