[7][8] Alsike clover is a perennial plant with a semi-erect, sparsely branched, grooved stem, hairy in its upper regions.

The individual florets have a five-lobed calyx and an irregular corolla consisting of five pink petals, one upstanding "standard", two lateral "wings" and the lower two fused to form a "keel".

[10] Trifolium Hybridum has been found to quickly lower the pH of soil, increasing its viable area of reproduction,[11] whilst reducing the bio-density of weeds by up to 57%.

[14] There is limited evidence of Trifolium Hybridum having toxic effects on horses including photosensitization and Alsike clover poisoning.

[15] A diet in equestrians of at least 20% Trifolium Hybridum over the course of four weeks could lead to poisoning which includes deleterious neurological effects and liver failure.
