• ‘Telegraph Improved’ is a classic English heirloom cucumber introduced during the late nineteenth century and traditionally grown in greenhouses.
• Its vigorous vines produce long, slender, dark-green cucumbers with thin skin, crisp flesh and very small, soft seeds. The flavor is mild, refreshing and non-bitter, making it an excellent choice for salads, sandwiches and fresh slicing.
• The fruits develop their best shape and quality when the vines are trained vertically on a tall, strong trellis. Regular harvesting encourages continued production.
