SF Tenacity

The perennial rye that survives

SF Tenacity is a persistent and high winter yielding perennial ryegrass. It has very early flowering to enable re-seeding in pasture mixes and is well suited to marginal dryland areas and where perennial ryegrass is used as a minor component in
the blend.

SF Tenacity is Australian grown and contains standard endophyte to aid persistence.

Agronomic features:
  • Persistent
    Well suited to marginal dryland situations. Can be included in mixes to improve persistence

  • Early flowering
    Enables re-seeding in short season areas. Can thicken up pasture swards for extended life of pasture

  • High winter yielding
    Used in mixes for carry over seed regeneration. Improves cool season production when feed is most needed
