The clover plants themselves are non-toxic and it is the fungus that contains the toxin slaframine that causes the undesirable symptoms in horses. 1993. To examine both the weather factor and suicide possibility, Olsen and his colleagues are testing different types of clovers in freeze chambers at controlled temperatures to see if survival is higher for either acyanogenic or cyanogenic plants. [15] The leaves form the symbol known as shamrock. U. Missouri Extension. It is low growing, with heads of whitish flowers, often with a tinge of pink or cream that may come on with the aging of the plant. Besides making an excellent forage crop for livestock,[37] its leaves and flowers are a valuable survival food: they are high in proteins, and are widespread and abundant.

Best Answer. Shamrocks grow best in full sun to partial shade and moist, well-drained soil, … [42], Repens means 'creeping' or 'stoloniferous'.[42]. Its leaves, like those of all other clovers, are made up of 3 leaflets grouped at the ends of the long leafstalks. [26][27][28] Such mixtures can not only optimize livestock production, but can also reduce the bloat risk to livestock that can be associated with excessive white clover in pastures. Humans lack the stomach for properly digesting clover. [36] For these reasons, it is often used as a green manure and cover crop. One poses that there are fewer herbivores in colder climates. Barnes, R. F., C. J. Nelson, M. Collins, and K. J. Moore (eds.). Forages: an introduction to grassland agriculture. Plant and Soil 253, no. If something damages the cell, these two compounds come into contact with each other and free cyanide is released.”.

White clover is native to Europe and Asia and was introduced some 300 years ago in North America. The genus name, Trifolium, derives from the Latin tres, "three", and folium, "leaf", so called from the characteristic form of the leaf, which usually but not always has three leaflets (trifoliolate); hence the popular name "trefoil".
