Plants to 20(-30) cm. Bulbs ovoid, 2-3 × 2-2.5 cm, offsets usually present, tunics dark brown. Leaves 3-6; blade channeled to subterete, narrowly linear, (10-)15-30(-40) cm × 2-5(-8) mm, apex abruptly contracted. Scape 8-25(-30) cm, usually ± equaling leaves. Racemes 20-40-flowered. Flowers: perianth tube blackish blue, obovoid to oblong-urceolate or cylindric, 4-6 × 2-3 mm, teeth white; fertile and sterile flowers ± equal (sterile may be slightly smaller and paler); pedicel declined or nodding, 3-5 mm. Capsules 5-7(-10) × 5-7(-10) mm. 2n = 18, 36, 45, 54, 72. Flowering early--mid spring. Roadsides, fields, woods, abandoned gardens; 0--1500 m; introduced; Ala., Ark., Conn., Del., D.C., Ga., Ill., Ind., La., Md., Mass., Mich., Miss., N.Mex., N.Y., N.C., Ohio, Pa., S.C., Tenn., Tex., Va., W.Va.; s Europe; n Africa; sw Asia; expected elsewhere. W. T. Stearn (1990) typified Hyacinthus racemosus and discussed the taxonomically different applications of that name and Muscari racemosum. The latter binomial, misattributed to (Linnaeus) Miller, sometimes has been used for what is correctly called M. neglectum.
Perennial herb with a bulb to 30 cm tall Leaves: basal, three to six, 15 - 30 cm long, 1 - 3 mm wide, narrowly linear with a recurved tip, almost cylindrical, channeled along one side. Inflorescence: a terminal, dense cluster (raceme) of twenty to forty flowers on an upright stem. Flowers: nodding, blackish blue, 4 - 6 mm long, 2 - 3 mm wide, egg-shaped to oblong- urn-shaped to cylindrical, with six small, white teeth. Stamens six. Anthers dark blue. Fruit: a three-angled capsule, 5 - 7 mm long, 5 - 7 mm wide. Seeds six.
Similar species: The similar Muscari botryoides differs mainly by the shape and width of its leaves, which are flat and mostly over 3 mm wide.
Flowering: late April to early May
Habitat and ecology: Introduced from Europe. A rare escape from cultivation, usually as a lawn weed.
Occurence in the Chicago region: non-native
Etymology: Muscari comes from the Greek word moschus, which means musk. Neglectum means overlooked.
