New energy from your kitchen | Microgreens in autumn: small plants, big nutrientsHow do you recognize hairy foam?
The hairy one Foamweedbelonging to the cruciferous family (Brassicaceae), it is characterized by its delicate white flowers which appear at the end of winter, usually starting in March. The plant initially grows in the shape of a rosette close to the ground, but in ideal conditions it can reach a considerable height. What makes it special are its hairy stems and leaves, from which it gets its name. This basal rosette consists of a cluster of leaves that grow directly at the base of the plant and spread out in a circular arrangement. Leaves in the rosette are typically larger and often pinnate, with several small, rounded to oval leaflets per leaf.
This rosette-shaped growth habit is characteristic of many plants in the cruciferous family (Brassicaceae) and serves several purposes, including the efficient use of light on the soil in the early growth stage and the storage of nutrients for rapid growth early in the growing season. After the plant reaches a certain maturity and begins to form one or more erect stems to produce flowers and subsequently seeds, the rosette is left on the ground as the base of the plant.
