Telegraph Improved, often called English Telegraph, is a heirloom greenhouse cucumber dating to the 1800s in England, developed for the long, smooth, seedless-style fruit associated with English hothouse cucumbers. It produces very long, slim, dark green fruits typically twelve to eighteen inches long with thin, tender skin and mild, crisp, nearly seedless flesh when grown under protection. Traditionally grown in glasshouses and now in high tunnels, it thrives with warmth and support. The fruits are burpless and excellent for fresh eating and salads. Maturing in about 60 days, it rewards attentive growing with steady moisture and a trellis to keep the long fruits straight. This heritage variety remains popular with gardeners who want classic English-type cucumbers and can provide the sheltered, warm conditions it prefers.
