Specifications & Description
Life Cycle:
Perennial.
Habitat:
Rocky places, Garigues, Steppes, and valley tops. Commonly found along waysides.
Frequency:
Very Common
Localities in Malta:
Very Common throughout the garigues and upper valley sides of the Maltese Islands. Cannot be missed during November and December.
This plant is usually described as annual but in Malta (as in certain places in Zone 9 and 10), climate conditions are favourable, and the plant can live all year long. Thus in Malta its life cycle is described as perennial. The plant has an ascending or prostate stem which is glabrous and has many short sub-branching stems. They form long raceme inflorescences with planty of scented flowers that are produced in most months of the year.
The leaves are quite small (about 30mm long) and simple, arranged alternately along the lower part of the stem. They have a fusiform shape, smooth outline, and have shiny greyish green colour due to the presence of many flattened fine white bristles.
The lying stems arise erect few centimetres below the location where the inflorescence starts. The plant produces racemes of very small flowers which can be few centimetres short or grow fairly long. The tiny flowers of about 5mm in diameter, are almost always white in colour in Malta, but there are plants described with lavender or pale purple flowers. As in racemes, the small flowers are densely clustered at the tip of the stem, and further down they get more spaced as they develop to the fruit,
The flowers have 4, small, circular white petals; 4 sepals; 6 tetradynamous stamens (4 long and central, 2 short and lateral) which are yellow and a central very small pistil deep inside the flower which can hardly be seen by the naked eye. The flowers give off a pleasant scent similar to honey and particularly noted when flowers are in plentiful clusters.
After fertilisation, the petals and other parts fall off, leaving a small, circular seed pod of 3.5mm across which is attached to the stem by a long stalk. This structure is called a silicule. At its apical edge the silicule has a characteristic small rod-shaped projection, which previously was the style+stigma of the flower. There can be only two seeds present per silicule. When the fruit is ripe, the 2 walls forming the outer halves of the silicule fall off and expose the seed outside. These fall down without any means of dispersion leaving a translucent partition (called the replum).
The peach-brown seeds are very small (just about 1mm in diameter), circular in shape and flattened.
Information and Details
Cultivation Notes:
Succeeds in an ordinary garden soil in a sunny position [200]. Succeeds in sandy soils [188]. Grows well on dry walls [1]. Tolerates maritime conditions [200]. Although a short-lived perennial, it soon loses its compact habit if grown for more than one year and so is usually grown as an annual plant in gardens [245]. A very ornamental plant, there are several named forms developed for their ornamental value. This species usually self-sows in the garden if growing in a good position [1]. A fast-growing plant [188], it makes a good edging to a plant bed. The forms of this species with white flowers have the refreshing scent of new-mown hay - flowers of other colours having little or no scent. [245] A good bee and butterfly plant [17, 30].
Medicinal Uses:
The plant is commonly used in Spain as an antiscorbutic ( can be used to treat scurvy = lack of vitamin C [271] ) and diuretic ( promotes the flow of urine [271]) . It is also highly esteemed as an astringent ( causes shrinkage and drying of surface membranes [271]) in the treatment of gonorrhoea. [240]
Edible Uses:
The young leaves, stems and flowers are sometimes used as a flavouring in salads and other dishes where pungency is required. [183]
Other Uses:
In his book "The Omnivore's Dilemma" Michael Pollan talks about an organic farm that plant sweet alyssum between every few rows of lettuce since it attracts the lacewings & syrphid flies that eat the aphids that molest the lettuces. [Personal communication by Kirk M. Wuest]
Personal observations:
Miscellaneaous
It has been reported that there are violet and apricot coloured flower variants of this plant. In Malta these are very rare or more probably do not grow at all. Only the white form predominates in Malta. [SM]
The scent of this flower is very sweet and is very similar to honey. [SM]
The flowers of this plant is mostly observed in November when most of the wild plants are not yet in blossom. During late winter and spring these low plants may be masked by other dense and higher plants. They are often easily seen in Winter and Spring in rocky waysides where there is not much high or dense plants (for example the invasive Oxalis pes-caprae) growing around [SM]
