This species is from central and eastern Europe, extending locally westwards to Britain and the Pyrenees. It grows in light sandy or gravelly soils, often near large rivers.
Botanical Description
This is a glabrous perennial, sometimes caespitose and woody at base. The stems are 10-80cm, erect or ascending, decumbent.
The leaves are 1-3mm wide, linear or linear-lanceolate, entire, 1- to 3-veined. The pedicels are erect.
The inflorescence is few- to many-flowered. The sepals are 3.5-6mm, unequal, with three main veins. The outer sepals are narrower than the inner and with an acute or acuminate apex. The inner sepals are with acute or obtuse and entire, scarious margins. The petals are blue, 3-4 times as long as the sepals, obovate or obovate-Ianceolate, tapering gradually to a yellow, pubescent claw. It has 5 stamens, alternating with 5 rudimentary staminodes. The stigmas are capitate.
The capsules are 5-8mm, subglobose.
