Botanical Description
Perennial short-rhizome herbaceous plant. The rhizome is horizontal, 0.5-1 cm thick, black-brown, with filiform adventitious roots.
The stem is erect, up to 60 cm tall, usually single, covered with short sparse hairs directed downward.
Leaves of vegetative rosette shoots 10-20 cm wide up to 40 cm long, covered with bristly hair petioles. Leaf blades are thin, up to 12 (18) cm long and of the same width, kidney-heart-shaped, shortly pointed at the apex, whole-extreme, dark green above, lighter underneath, pubescent with fine bristled hairs on both sides.
Generative shoots 10-40 cm tall. The leaves on them are much smaller than the basal ones, 3-5 cm long, 1-3 cm wide, decreasing to the top of the stem, the lowest of them on the short petiole, oblong-ovate, elongated pointed; middle and upper leaves sessile, oblong or lanceolate, acute.
Peduncles emerge from the sinuses of the upper stem leaves and exceed them. The flowers are first collected in a cochlea-folded inflorescence , with full flowering - loose paniculate.
Calyx almost to the base dissected into narrow lanceolate lobes 2 mm long, densely short bristly.
Corolla is blue, in the throat is white, partially fused, the tube is barely longer than the cup. The limb is flat about 4 mm in diameter, its lobes are rounded or obovate, equal in length to the calyx tube.
Flowering May – June.
Fruit - a nutlet up to 3 mm long, half-bent, with a sharp tip, wrinkled.
The diploid number of chromosomes is 2n = 48 [4] .
Geographical distribution and ecology
Geographical distribution - Western Ciscaucasia , Western Transcaucasia , Kakheti [5] .
It grows in shady forests, sometimes in subalpine meadows. Cryptophyte , geophyte [6] .
Outside of its natural range, it is cultivated as an ornamental plant and runs wild in the European part of Russia.
In the Flora of the middle strip of the European part of Russia P.F. Maevsky there is an indication that often for Central Russia, as a widely cultivated ornamental plant, the Caucasian species of Brunnera macrophylla is mistakenly indicated, instead of the Siberian Brunnera sibirica actually grown - Brunnera sibirica [7] .
Economic value
Floriculture Application
In culture since 1825 [5] . In decorative floriculture, Brunner Siberian is used for group plantings, borders and on rocky hills [2] . Since by the middle of summer it loses its decorativeness, it is desirable to plant it in mixed group plantings, decorating with other decoratively stable plants [8] .
Large-leafed Brunner has garden forms and varieties that are valued for variegated broad-hearted leaves [9] ː
