Arrowleaf Clover

(Trifolium vesiculosum)

Deep Rooted later flowering Clover.

Highly productive with deep root structure enabling excellent late spring / early summer growth. Adapted to deep acid sands. Suitable for grazing, hay and silage. Non Bloating.

Arrowleaf Clover key attributes:

  • Late maturity – extends grazing period into summer.
  • Deep rooting ability – exploits deep subsoil moisture.
  • High dry matter yield.
  • Suppression of summer weed species.
  • High proportion of hard seed for persistence.
  • Seed production – simple and economic.

The role for Arrowleaf Clover in a Subterranean Clover or Medic pasture is to produce a bulk of high quality feed from moisture which is beyond the rooting depth of Subterranean Clovers, or from rain falling after the Subterranean Clovers have senesced.

Arrowleaf Clover extends the grazing phase beyond that of traditional Subterranean Clover pastures by some 4 to 8 weeks into summer. This extended growth into summer provides high quality grazing and suppresses growth of summer weeds.

Arrowleaf clover is predominantly a hard-seeded species like Rose Clovers and Serradellas, consequently regeneration in the second year may be low if the pasture is not grazed after the sward ‘hays-off’. Consumption of the mature seed heads by livestock often improves sward regeneration in subsequent years.

Arrowleaf Clover is an erect growing, temperate annual legume, commonly reaching one metre in height. It is semi-winter dormant, with most active growth occurring in spring and early summer.

Arrowleaf Clover has a strong stem which is not prone to lodging. Its leaves are large, with distinctly arrow-shaped white markings in the middle of the mid rib.

  • Recommended pH Rate: 5+

  • Recommended Rainfall Rate: 400mm+

  • Recommended Sow Rate: 3 to 10 kgs/ha.

Arrowleaf Clover is recommended as a mix component with other Subterranean Clovers or Annual Medics, rather than as a pure sward.
