'''''Alyssum''''' is a [[genus]] of about 100-170 species of [[flowering plant]]s in the family [[Brassicaceae]], native to [[Europe]], [[Asia]], and northern [[Africa]], with the highest species diversity in the [[Mediterranean region]].
 +
 
 +
The genus comprises [[annual plant|annual]] and [[perennial plant|perennial]] [[herbaceous]] plants or (rarely) small [[shrub]]s, growing to 10–100&nbsp;cm tall, with oblong-oval leaves and yellow or white flowers (pink to purple in a few species).
 +
 
 +
The genera ''[[Lobularia]]'' and ''[[Aurinia]]'' are closely related to ''Alyssum'' and were formerly included in it. The widely cultivated species popularly known as &quot;Sweet Alyssum&quot; is ''[[Lobularia maritima]]''. The common rockery plant is ''[[Aurinia saxatilis]]''.

Alyssum (classical name). Cruciferae. Low plants with many small clustered flowers, grown in the open and often used in rock-gardens.
 +
 
 +
Plants branching, often tufted: fls. white or yellow, sometimes varying to rose; filaments often notched: fr. a small orbicular pod, with 1 or 2 wingless seeds in each of the 2 compartments; valves of pod nerveless, flattened at the margins.—As many as 100 species in middle Eu., Medit. region and the Caucasus.
 +
 
 +
The sweet alyssum is one of the commonest annuals, grown both in the open and forced in benches, beds or pots. It is of the easiest culture, either indoors or out. The compact varieties are most prized for pot culture. Under glass, it requires temperature of a carnation house. It will stand considerable frost in the open, and may be sown early; it blooms all summer, and until killed by winter. Useful for window-gardens and baskets. For winter bloom, sow seeds late in August or in September. When blooms begin to fail, cut back the plant, and it will bloom again.
 +
 
 +
The perennial alyssums require no special treatment. They are usually propagated by dividing the roots; also by cuttings and seeds.

For the plant with the common name Alyssum, click here.

Alyssum is a genus of about 100-170 species of flowering plants in the family Brassicaceae, native to Europe, Asia, and northern Africa, with the highest species diversity in the Mediterranean region.

The genus comprises annual and perennial herbaceous plants or (rarely) small shrubs, growing to 10–100 cm tall, with oblong-oval leaves and yellow or white flowers (pink to purple in a few species).

The genera Lobularia and Aurinia are closely related to Alyssum and were formerly included in it. The widely cultivated species popularly known as "Sweet Alyssum" is Lobularia maritima. The common rockery plant is Aurinia saxatilis.


Read about Alyssum (genus) in the Standard Cyclopedia of Horticulture 

Alyssum (classical name). Cruciferae. Low plants with many small clustered flowers, grown in the open and often used in rock-gardens.

Plants branching, often tufted: fls. white or yellow, sometimes varying to rose; filaments often notched: fr. a small orbicular pod, with 1 or 2 wingless seeds in each of the 2 compartments; valves of pod nerveless, flattened at the margins.—As many as 100 species in middle Eu., Medit. region and the Caucasus.

The sweet alyssum is one of the commonest annuals, grown both in the open and forced in benches, beds or pots. It is of the easiest culture, either indoors or out. The compact varieties are most prized for pot culture. Under glass, it requires temperature of a carnation house. It will stand considerable frost in the open, and may be sown early; it blooms all summer, and until killed by winter. Useful for window-gardens and baskets. For winter bloom, sow seeds late in August or in September. When blooms begin to fail, cut back the plant, and it will bloom again.

The perennial alyssums require no special treatment. They are usually propagated by dividing the roots; also by cuttings and seeds.

Many other species of alyssum are likely to be found in choice rock-garden collections. A. alpestre. Linn. 3 in., grayish: fls. yellow, in simple raceme.—A. atlánticum, Desf.-A. montanum.—-?. Bertholonii, Desv.-A. argenteum.—A. cuneifolium, Tenore-A. montanum.—A dasycarpum, Steph. Annual: fls. yellow.—A. diffùsum, Tenore-A. montanum.—A. mocrocarpum, DC. Shrubby, somewhat spiny, 8 in.: Lvs. oblong, silvery: fls. white.—A. orientale, Ard. 1 ft.: Lvs. lanceolate, toothed, downy: fls. yellow, in corymbs.—A. tortuosum, Rupr. 6 in., at. twisted: lvs. narrow, hoary: fls. yellow, in corymbs.
