Hyacinthoides non-scripta is a perennial plant that grows from a bulb. It produces 3–6 linear leaves, all growing from the base of the plant, and each 7–16 millimetres (0.28–0.63 in) wide. An inflorescence of 5–12 (exceptionally 3–32) flowers is borne on a stem up to 500 mm (20 in) tall, which droops towards the tip; the flowers are arranged in a 1-sided nodding raceme. Each flower is 14–20 mm (0.55–0.79 in) long, with two bracts at the base, and the six tepals are strongly recurved at their tips. The tepals are violet–blue. The three stamens in the outer whorl are fused to the perianth for more than 75% of their length, and bear cream-coloured pollen. The flowers are strongly and sweetly scented. The seeds are black, and germinate on the soil surface.

The bulbs produce contractile roots; when these roots contract, they draw the bulbs down into deeper layers of the soil where there is greater moisture, reaching depths of 10–12 cm (3.9–4.7 in). This may explain the absence of H. non-scripta from some thin soils over chalk in South East England, since the bulbs are unable to penetrate into sufficiently deep soils.

H. non-scripta differs from H. hispanica, which occurs as an introduced species in the British Isles, in a number of ways. H. hispanica has paler flowers which are borne in radially symmetrical racemes; their tepals are less recurved, and are only faintly scented. The outer stamens are fused with the tepals for less than 75% of their length, and the anthers are the same colour as the tepals. These two species are thought to have diverged 8000 years ago. The two species hybridise readily to produce fertile offspring known as Hyacinthoides × massartiana; the hybrids are intermediate between the parental species, forming a spectrum of variation which connects the two.
