Cucumis sativus

  • Excellent flavour
  • 12.5 - 15cm fruit
  • Long season producer
  • High disease resistance

‘Silver Slicer’ is a refined white cucumber producing crisp, juicy 12.5–15cm fruits with tender, thin white skin and exceptional flavour. The pale green flesh is sweet, refreshing, and never bitter, making this one of the finest fresh-eating cucumbers for summer harvests.

Plants are vigorous and highly productive across a long season, continuing to yield abundant harvests well after many other cucumbers begin to decline. The smooth, ivory-white fruits are best picked young for peak tenderness and crunch.

Developed by breeders at Cornell University, ‘Silver Slicer’ combines the outstanding flavour and delicate white skin of the heirloom ‘Boothby’s Blonde’ with improved resistance to powdery mildew — resulting in a cucumber that is both beautiful and reliable in the garden.

An excellent choice for fresh salads, slicing, and summer grazing straight from the vine.
