Lamb's quarters (Amaranthaceae)
Flowering: June - August
The genus Chenopodium includes many different species of which the characteristics are often difficult to discern.These species are found on ploughed land such as cultivated areas, construction sites and wastelands but also in gardens, vegetable gardens and along paths. Note that these nitrophilous plants are good indicators of a soil rich in nitrogen. These weeds bloom from early June to late August. Lamb's quarter (or goosefoot) flowers are small, greenish, aggregated in fairly dense inflorescences springing from the axils of the leaves, forming a large panicle at the stem extremity. Lamb's quarter pollen is present in the air in very small amounts from June to August. Allergic sensitization to this type of pollen is rather rare.
