Geographical Distribution and Habitat –
Solidago virgaurea is a species in the temperate-cold areas of Europe, Asia and North America. Its diffusion in Italy is in all regions except in Sicily. Its habitat is that of rather fresh woods and at their edges and clearings, on fresh clayey soils, poor in carbonates, from neutral to subacids, from sea level to the subalpine belt.
The goldenrod is a perennial herbaceous species with an erect stem that can grow up to 80 cm.
The basal leaves are lanceolate and with a notched margin while those of the stem are sessile and gradually become smaller towards the top of the plant.
The inflorescence is formed by numerous racemes, placed in the axil of the leaves, each of which is made up of some yellow flower heads; the flower heads are made up of ligulated flowers arranged externally in a single circumference and tubular flowers arranged in the center.
The flowering period runs from July to October.
The fruit is an achene which has a more or less cylindrical shape, with the ends thinned and equipped with a pappus, a structure that facilitates its dispersion through the wind.
The goldenrod is however a plant characterized by extreme variability.
Solidago virgaurea is a spontaneous herbaceous plant, often present in grassy clearings and stony pastures that grows mainly on fresh clayey soils, poor in carbonates, and with neutral or subacid pH.
However, it can be grown from seed from sea level to the subalpine belt.
It is an easy-to-grow plant and can quickly decorate large areas.
