'Snake bean' is a plant in the Vigna genus with a scientific name of Vigna unguiculata sesquipedalis. The botanical name epithet for Snake bean (unguiculata) means 'furnished with a claw'.
A vigorous climbing annual> The plant begins to produce long pods, ranging from 35 to 75 cms 60 days after sowing. The pods hang in pairs that should be picked for vegetable uses before matured. The snake bean is a subtropical/tropical plant and is widely grown in Southeastern Asia, Thailand and Southern China. It is a very interesting plant to grow – you almost need to check/harvest long beans everyday because they grow very quick in warm climates. It is, however, sensitive to the temperature and grows relatively slow in mild/cold environments. Like growing common beans, it is recommended to rotate the planting locations every year for getting the best results – do not repeat planting at the same spots within 3-4 years. Edible pods are very crisp, tender and delicious. Long beans are cut into shorter sections and cooked like common green beans. There are many varieties grown and they are generally identified by the color of the matured seeds.

Blooms appear in these approximate colours: White smoke and Bright lavender and Dark pastel purple. When ripe, fruit appear in these approximate colours: Yellow-green and Grade 1 Paint Green. Leaves appear approximately as a Napier green and Yellow-green
Snake bean grows as an annual and is an edible vegetable. Being an annual plant, it tends to grow best over the course of a single year.
Normally growing to a mature height of 2.00 metres (6.50 feet), Snake bean grows with a climbing habit.
Snake bean is normally quite a low maintenance plant and is normally very easy to grow - great for beginner gardeners!

Culture: In the Northern Territory snake beans are planted as seed into slightly damp and warm soil with 1-2 seeds in each planting hole or “hill”. After sowing, water should be withheld until germination has occurred (3-5 days). The planting bed should be mounded if waterlogging during the season is expected. The planting is usually into single rows about 3 m apart with 30-60 cm between “hills”. The plants are encouraged onto trellises.
In the Northern Territory snake beans will benefit from extra organic matter added before planting via either a green manure crop or an application of animal manure. This organic matter should be well broken down before planting. An application of NPK fertiliser and calcium just before planting can also be used as well as further applications of fertiliser (either urea or NPK) during the season. However care must be taken to not over-supply nitrogen as that can lead to excessive growth and reduced yields.
Snake bean yields also decline if water is under-supplied so care must be taken to keep soil moisture high.
Pests and Diseases: Rusts, mildews and some viruses can seriously affect snake beans though in the main they are only mildly susceptible to most fungal diseases. However in the Northern Territory fusarium wilt is becoming a very major problem, as are root-knot nematodes. The vectors for most viral diseases (aphids and white flies) can also cause problems.
The major insect problems for snake beans apart from those mentioned above are cutworms, bean flies and mites.
Fruiting Season: Seed germination occurs within 3-5 days of planting with flowering starting in the fifth week after sowing. Fruit can be harvested two weeks after first flowering. Depending on crop health and harvest intensity, plant senescence starts 6-8 weeks after sowing with plant death usually within four months of sowing.
Harvesting: This can start within seven weeks of planting. The best harvest stage depends on variety and market requirements however the fruit are normally picked when the outline of the seeds is just
visible on the outside of the pods. When picking, all suitable pods should be removed as pods that are allowed to fully mature (ie: pods are hardened and seed swollen) will exhaust the plant. Picking should be done at least twice a week though in hotter climates picking may be required more frequently.
A full sun position will ensure your plant thrives and remember to water often. Zone 11 to 14 are typically the USDA Hardiness Zones that are appropriate for this plant (although this can vary based on your microclimate). Ideally plant in sandy soil and try to keep the ph of your soil between the range of 5.5 and 7.5 as Snake bean likes to be in weakly acidic soil - weakly alkaline soil.
