Vegetative characteristics

The Woll-Ziest grows as a perennial herbaceous plant and reaches heights of about 60 to 80 centimeters. The aboveground parts of the plant are mostly dense gray or white, silky-woolly hairy ( indument ). The stems are square.

The opposite arranged leaves are divided into a petiole and a leaf blade. The very short petiole is almost encompassing the stem, it can be almost entirely absent. The simple leaf blade of the lower stem leaves is elongated-elliptical with a length of about 10 centimeters and a width of about 2.5 centimeters with a narrowed blade base and a pointed upper end. The leaf margin is notched to entire.

Generative characteristics

The annual inflorescence contains multi-flowered pseudo whorls with 15 to 20 flowers each, which, apart from the lowest one to three, are close together. The bracts are almost sessile and tiny, with the lowest slightly longer and the uppermost shorter than the pseudo whorls. The bracts are linear to linear-lanceolate with a length of about 6 millimeters.

In Central Europe the flowering time extends from June to July, depending on the location it can also last until August. The seated, hermaphrodite flowers are zygomorphic and five-fold with a double flower envelope . The five approximately 1.2 centimeters long sepals are fused tubular-bell-shaped. The slightly curved calyx is ten-nerved and bald, only the calyx teeth are hairy on the inside, or closely haired on the outside. The oval-triangular calyx teeth, 2 to 3 millimeters long, are almost the same, or the rear ones are larger, and the tips are stiff. The 1.2 cm long corolla is hairy and woolly, only its base is bare and it is two-lipped. The corolla tube is about 6 millimeters long. The upper lip is egg-shaped with a smooth edge. The lower lip is almost expanded with broad, ovate central lobes and elongated side lobes. There are four stamens , the front pair of which is longer. The stamens are hairy from their base to the middle. The stylus towers over the corolla.

When ripe, the elongated nuts are brown and bare.

The number of chromosomes is 2n = 30.

distribution

Stachys byzantina is native to the Middle East and the Caucasus . There are information about the place of discovery from Armenia , Azerbaijan , northern Iran and northern Turkey , here partly also further south, in western central Anatolia. She is a neophyte elsewhere , for example in the Crimea . In Italy, the species occurs almost only subspontaneously and adventively , especially near cemeteries.

Taxonomy

The valid first description of Stachys byzantina was made in 1849 by Karl Heinrich Koch in Linnaea , Volume 21, p. 686. Synonyms for Stachys byzantina Koch are: Eriostomum lanatum Hoffmanns. & Link , Stachys lanata Jacq. nom. illeg., Stachys olympica Poir. Zefir , Stachys taurica . The specific epithet byzantina refers to the site of Byzantium, the former name of the city of Istanbul .

Stachys byzantina belongs in the genus Stachys in the section Eriostomum , subsection Creticae . Closely related species are common in the eastern Mediterranean and Anatolia; Sister species could be Stachys cretica .

use

Some varieties of the Woll Ziest (for example 'Silver Carpet', 'Cotton Boll', 'Primrose Heron') are used as ornamental plants . The Woll-Ziest is mainly used as a ground cover, for example for Mediterranean gardens, green roofs , in the Alpinum and in the scree garden , between wide tile joints. It can be planted outdoors in USDA climate zones 4–9 and is frost hardy there.
