Main description


Seedling
Hairy nightshade cotyledons can range from 4-9 cm in length. Its leaves are lanceolate in shape and have very small transparent hairs. The hypocotyls have distinctively longer not transparent hairs which aid in the identification of this broadleaf weed. The cotyledon is dark green in colour and remains dark green throughout growth.

 

Mature plant
Can grow up to 100 cm in height, leaves can range anywhere between 2-15 cm and grow in an alternating distribution, with petioles (connection between leaf and main stem) ranging up to 4 cm in length. Leaves are green on upper and lower surface. Stems of this plant are green but can often have a purplish appearance under strong sunlight. Flowers are white in colour with 5 lobes that are narrow and are pointed at tips. Its stamens are yellow and begins flowering in May.

 

Optimal growth conditions
Hairy nightshade prefers cultivated fields, both mineral and muck.
