In the medieval and early post-medieval centuries, various glasswort plants were collected at tidal marshes and other saline places in the Mediterranean region. The collected plants were burned.

Wood ash is the powdery residue remaining after the combustion of wood, such as burning wood in a fireplace, bonfire, or an industrial power plant. It is largely composed of calcium compounds, along with other non-combustible trace elements present in the wood, and has been used for many purposes throughout history.

[2] Plants of the genus are known commonly as wood-rush, [3] wood rush, or woodrush. [4]
Some trees play a tune, using vines for harp strings and a chorus of robins. A fight breaks out between a waspish-looking hollow tree and a younger, healthier tree for the attention of a female tree.

The flowers have six brown to black tepals 2 to 4 mm (0.08 to 0.16 in) long. [ 7 ] Common woodrush is fairly easy to identify with its leaves fringed with long, white hairs (common for Luzula species) and the terminal, spike clusters of 6-parted flowers on variable length stalks, replaced by round capsules starting in late spring.
