Vegetative characteristics

The common coniferous herb is an evergreen dwarf shrub that reaches heights of growth of 5 to 10, rarely up to 20 centimeters. The shoot axes are prostrate or ascending. The bark is hairy close-fitting with glandular hairs.

The alternately arranged leaves are needle-shaped with a length of 4 to 20, usually 5 to 18 millimeters and a width of 0.5 to 0.2 millimeters. Stipules are absent.

Generative characteristics

The flowering period extends from June to October and they only bloom in the morning. There are one or two flowers per axilla. The flower stalk is as long or shorter than the nearby leaves.

The hermaphrodite flowers are radially symmetrical with a double flower envelope . The sepals are unequal in length. The obsolete petals are 6 to 10 millimeters long. The outer stamens are sterile.

The number of chromosomes is 2n = 32.

ecology

The common coniferous rose only blooms in the morning and only in sunshine; In the afternoon the petals have already fallen off. There are various visitors to the flowers, but self-pollination occurs especially before the flowers bloom .

The capsule fruits fall off as a whole and spread out as trolleys, in addition to which glue spreads through the coagulating seeds .

Occurrence

The common coniferous herb occurs in warm to warm temperate Europe and West Asia on limestone rock corridors and dry grasslands as well as on rich sandy dry grasslands. The common needle rose is limestone . In Central Europe it is a character species of the Xerobromion association , but also occurs in plant communities of the Koelerion glaucae.

Taxonomy

It was first described in 1824 under the name ( Basionym ) Helianthemum procumbens by Michel Félix Dunal . The new combination to Fumana procumbens (Dunal) Gren. & Godr. was published by Jean Charles Marie Grenier and Dominique Alexandre Godron .

use

The common coniferous herb is rarely used as an ornamental plant for rock gardens.
