Summary
DescriptionTrifolium vesiculosum habit2 (10735543215).jpg |
Introduced, cool-season, semi-erect, annual legume. Stems are thick and hollow. Juvenile trifoliate leaves are club shaped while mature leaves are arrow shaped with white or reddish arrow-shaped marks. Flowerheads are large (up to 10 cm long) conical clusters of many pea-like flowers, each initially white then turning pink. Flowering is from late spring to early summer. A native of Europe and western Asia, it is a sown species that is suited to well drained soils of moderate to high fertility. It has poor tolerance of waterlogging during establishment. Sown in mixtures for short-term pastures or as a component of high-density legume crops. An alternative to crimson clover and red clover, it is a productive, late maturing forage that produces large quantities of dry matter in spring. Considered a bloat safe legume. Good spring rainfall or irrigation is required to reach its potential yield. Extremely deep roots result in continued growth longer than most annual legumes. • Well suited to silage and hay production. • Rest from grazing once flowering commences to maximise seed-set. However, high levels of hard seed often result in poor regeneration in the second year. • Graze heavily once seed is mature, as zero residues in autumn maximises regeneration. |
