Here is a spectacular plant that forms small bright bushes that you will see during your holidays in the Mediterranean scrub (or during all its flowering if you live there) or like us in a garden. Roland
Scientific name: Linum campanulatum L., 1753
Origin of the name: comes from the Greek “linon”, flax and from the Latin “campanulum”, which means “bell-shaped”.
German/ dialect: Glöckiger-Lein
English: yellowflax
Date and place of observation: July 8 at the botanical garden of Saverne (67), photos taken on June 10 near Sisteron (Alpes-de-Haute-Provence)
Family of plants: Yellow Flax is part of the Linaceae family which includes 290 species divided into 10 genera, flowers, lianas and some trees. These plants are present almost everywhere but rather in cold to tropical areas. They have a similar appearance to caryophyllaceae, the carnation family. The leaves are entire and arranged in a spiral. Their symmetry is of order 5, 5 free petals, 5 free or fused sepals at the base, 5 stamens or 5 fertile and 5 sterile stamens, 2 to 5 fused carpels. Linaceae are important especially for cultivated flax, Linum usitatissimum, widely used for its fiber and its seeds.
Category: perennial Habit: medium bushy plant with large yellow flowers Height: 10 to 30 cm high.
Stem: woody, glabrous, branched with long annual branches
Leaves: the leaves are entire, subopposite and sessile (without the small stalk that usually holds the leaves). They are lanceolate, or oval, and measure about 4 cm long and 1 wide. Towards the top of the stem their width decreases to become linear.
Flowering: April to June
Flowers: yellow in color, 3 cm long and made up of 5 petals, the end of which is oval and not indented. The calyx surrounds the corolla with its 5 free, linear sepals, and twice as small as the petals. The pistil ends in 5 stigmas carried by 5 styles of 0.5 mm. The flowers are bent before flowering and then straighten.
Pollination: by insects Fruits: round fruits called capsules. It is through ten slits that the seeds of less than 1 mm, smooth, escape at maturity.
Habitat: sunny places with poor or stony soil rich in alkalines such as limestone lawns, scrubland, embankments and edges of roads up to 1400m.
Possible confusion: no, it is really typical but there is a sister species, very close, Linum flavum in Mediterranean countries
Protection status: common plant without protection status but classified Znieff in the Midi-Pyrénées region. The ZNIEFF, Natural Areas of Faunistic and Floristic Ecological Interest aim to identify and describe sectors with strong biological capacities and a good state of conservation.
Food and medicinal use: nothing found In the Linaceae of our country, it is the cultivated Flax, with large blue flowers, Linum usitatissimum which has remarkable food and medicinal value.
