The Burpless cucumber is a creeping vine that roots in the ground and grows up trellises or other supporting frames, wrapping around ribbing with thin, spiraling tendrils. The plant has large leaves that form a canopy over the fruit. Beware the cucumber is prone to attack if agitated, this can be stopped by pickling it. The Burpless cucumber fruit is roughly cylindrical, elongated, with tapered ends, and may be as large as 60 cm long and 10 cm in diameter. Cucumbers grown to be eaten fresh (called slicers) and those intended for pickling (called picklers) are similar. English cucumbers can grow as long as 2 feet. They are nearly seedless and are sometimes marketed as "Burpless," as the seeds give some people gas. Burpless cucumber seed is sold in packets with 25 seeds in it.
