The Vinca that Fights Back.

  • Reduced Risk: offers season-long flowering and survival in landscape plantings. Highly resistant to ten of the most virulent isolates of Phytophthora nicotianae that cause Phytophthora blight on annual vinca.*
  • Easier to grow: improved branching, uniformity, and floriferousness ideal for premium packs and small to larger pots.
  • Higher consumer appeal: large showy flowers in the widest range of solid and high demand bicolor patterns of any disease resistant vinca on the market.

* Confirmed in collaboration with Clemson University; these isolates were found at growers and in landscapes across the southern U.S.
