The stylus is 5 to 6 millimeters long.
The fruit ripens from September to October. The hairy capsule fruit is inverted-heart-shaped, rounded and more or less edged. The seeds are 1.5 millimeters long.
The number of chromosomes is 2n = 64.
ecology
The great speedwell is an herbaceous chamaephyte .
The flowers are feminine. A wide variety of insects can be used as pollinators . Even self-pollination occurs.
The Great Speedwell is a dehydration spreader, animal and wind spreader , also a gardener and ants spreading takes place.
Occurrence
The Great Speedwell comes from northern Germany to the Balkans and to the east it penetrates to eastern Siberia , the Altai , China and Mongolia. It occurs scattered in Central Europe .
In Germany , the Great Speedwell is sometimes quite widespread in the central and southern regions; however, in the north and northwest it is largely absent. In Austria and Switzerland , Veronica teucrium is generally found scattered.
The Great Speedwell grows in bushes, on the edges of forests, in sparse forests and on semi- arid grasslands . He prefers more or less dry, mostly calcareous clay and weathered stone soils . He loves warmth. According to Ellenberg , it is a half-light plant, intermediate-continental distribution, a dry pointer. He is an association characteristic species dryness yield Ender blood geranium-Staudensäume (Geranion sanguinei), but is in Central Europe and in companies of the associations Mesobromion, Berberidion, Erico-Pinion or the order Quercetalia pubescentis ago.
Systematics
The first publication of Veronica teucrium was in 1762 by Carl von Linné . Synonyms are, for example, Veronica latifolia L. , Veronica pseudochamaedrys Jacq.
The great speedwell ( Veronica teucrium L. ) is considered by some authors as a subspecies ( Veronica austriaca subsp. Teucrium (L.) DAWebb ) of the Austrian speedwell ( Veronica austriaca ).
use
Some varieties are used as ornamental plants , for example 'Crater Lake Blue', 'Captain', 'Bright Blue', 'Royal Blue', 'Shirley Blue'.
