Parthenocarpic cucumbers are hybrid plants that have been bred with emphasis on the incompletely dominant gene Pc, which is responsible for these cucumbers to produce fruit asexually. These cucumbers produce few or no seeds, any seeds that do ripen will not be fertile -- parthenocarpic cucumber seeds must be sourced yearly.
Cucumber, Sweet Success Hybrid. When cucumber seeds are direct-sown along a cucumber fence, vines can be trained to grow upright for easy picking and to save space for other plants to grow. Good companion vegetable plants are direct-sown radishes, bush snap beans, and transplants of compact herbs, peppers, eggplants and tomatoes.
In looking at cucumber varieties, you'll see terms like "parthenocarpic" and "gynecoecous". Parthenocarpic cucumbers require no pollination, and are best for growing cucumbers in greenhouses, at lower temperatures, or where pollinator populations are low. Gynecoecous cucumbers produce mostly female (fruiting) flowers, to increase yields.
Cucumber seeds will not germinate at a soil temperature below 50°F (10°C). Sow 2 seeds/ft., 1/2" deep, in rows 6' apart. Thin to 12" apart. DISEASES: Practice crop rotation, residue sanitation, and choose disease-resistant varieties. Control insect pests to prevent bacterial wilt.

It is bitter free, seedless, does not require peeling and does not cause indigestion (burpless) like the American greenhouse types often do! Parthenocarpic means "seedless" or the fruit set without seed.
