Red and white clovers are sufficiently
well known to need no description. Both are perennial plants, the white species
being prostrate and enabled to spread vegetative by its habit of rooting at the
leaf nodes. Being members of the Pea Family (Leguminosae), clovers provide the
farmer with a valuable source of nitrogen as nodules on their roots are home to
bacteria which fix the element from the plentiful supply in the
atmosphere. Of the many dialect names by which clovers have been known, honeystalks and lamb-sucklings are amongst the most descriptive. The origin of the former will be obvious to anyone who has sucked the nectar from a clover flower, and the latter highlights white clovers value as a feed for sheep. In Titus Andronicus Shakespeare has Queen Tamora boast that she will enchant the old Andronicus |
But sheep will thrive in a clover-rich pasture, so why should Shakespeare refer to the plant as dangerous? Certain strains of white clover contain a cyanogenic glycoside which, when the plant is eaten, is converted to prussic acid - not the most healthful of dietary additives! But glycoside poisoning is rare. It is more likely that the country-born bard was thinking of the bloat which can affect (sometimes kill) sheep if they gorge themselves too greedily when transferred from a poor pasture to a highly palatable, clover-rich one. |
