Platinum – A new grass for all seasons with amazing winter growth and heat tolerance

  • Developed from high yielding New Zealand germplasm that is adapted to the Australian environment
  • Platinum delivers an advantageous combination of high winter spring and summer production as well as excellent persistence in a low endophyte variety
  • Breeding selection included screening for disease resistance, improved yield, and high tiller density
  • Highly dense diploid perennial which is mid to late flowering with dry matter yields ahead of most other diploid varieties
  • Its high winter herbage production sets the pasture up for spring, especially if cool wet conditions persist into early spring
  • Its high tiller density makes it extremely persistent after heavy grazing
