About Noccaea caerulescens (J.Presl & C.Presl) F.K.Mey.
Noccaea caerulescens (J.Presl & C.Presl) F.K.Mey. is a low-growing biennial or perennial plant. It produces small basal rosettes of stalked elliptic to lanceolate leaves that have smooth, unbroken margins. One or more flowering stems grow from the rosette, bearing small stalkless alternate leaves that clasp the stem. Its inflorescence is a dense raceme that continues to lengthen after flowering finishes. Individual flowers are radially symmetrical, measure about 5 mm (0.2 in) wide, and have white or pinkish petals. Each flower has four sepals, four petals, six stamens (four long and two short) with violet anthers, and a single carpel. The fruit is many-seeded, narrowly spatulate, and has a notched tip. This species flowers in late spring. In Europe, Noccaea caerulescens grows in Finland and Sweden, occurring in all regions except the most northerly areas. It can also be found in the Alps, the Massif Central, the Pyrenees, eastern Norway, southern Germany, and northern England. It grows in dry hillside meadows, forest margins, banks, gardens, lawns, pastures, field margins, yards, and open bare sites.
