Bur Gourd Cucumis anguria

The genus, Cucumis, is a family of cucumbers, an annual climbing or spreading vine and common vegetable grown for its crisp, green fruit. It is a member of the Cucurbitaceae (gourd) family, and can grow 8 to 18 inches high and 3 to 8 feet wide. If given proper soil and water, cucumber plants can be an incredibly prolific addition to your vegetable garden.

C. anguria, commonly called Maroon Cucumber or, also Gherkin,  is an herbaceous vining species of cucumber native to Africa that is not known in the wild and, although accepted as a species, is thought by some to be a cultivar. Maroon Cucumber is a climbing plant with thin stems that can reach a length of more than 7 feet. The plant grows best in full sun and moist, rich, well-drained soil. It prefers a slightly acidic ph, but will grow in less desirable soils. It has high water needs and requires consistent moisture for proper growth, but good drainage is also important. Keep the leaves dry while watering to prevent fungal diseases. Note that vertically grown cucumber plants lose moisture more easily.

Cucumber is frost sensitive and needs warm soil temperatures to germinate and grow. Seeds can be directly sown after the last frost or started indoors three to six weeks before transplanting, or less than four weeks before the last frost date. Be careful to avoid damaging the plant's taproot when transplanting. Cucumbers can be harvested green when they reach their preferred size; however, cucumbers that have turned yellow are over ripe and will be tough and difficult to eat. Poor pollination may lead to misshapen fruit. To pick, cut the stem attaching the fruit to the vine with a sharp, clean knife or clippers. Harvest often to spur further fruit production. 

Cucumber plants can be grown vertically on a trellis or even a wire fence, which increases air circulation, prevents diseases, and grows straighter fruits. It can also be grown in a container of a minimum size of 1 gallon and 8 inches depth. Cucumber is most well known for its use in salads and pickling, so its best landscape use is in an edible garden. 

Insects, Diseases, and Other Plant Problems:

There are pest and disease problems, such as cucumber beetles and aphids, that can generally be managed through good cultural practices.  

The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common cucumis diseases as well as a factsheet on common insect pests and other problems.
