  Bitter Melon / Bitter Gourd

  Momordica charantia

  Suitability for this climate: Recommended

  This profile covers cultivated Chinese-type and Indian-type bitter melon grown vertically for its immature edible fruit. It does not cover wild or weedy balsam-pear forms, ornamental Momordica species or ripe fruit grown primarily for seed. Bitter melon may escape cultivation and self-seed in warm climates, so prevent ripe fruit from splitting where spreading is a concern.

  Chayote / Choko (Trellised)

  Sechium edule

  Suitability for this climate: Recommended

  This profile covers cultivated chayote, known as choko in Australia, grown vertically for its edible fruit. It includes smooth, wrinkled and spiny green or pale-fruited forms of Sechium edule. Chayote is a tropical or subtropical perennial and may remain productive for several years in a suitable frost-free climate. In colder areas it may be grown as a long-season annual, although fruit production is often unreliable because flowering is stimulated by short days. This profile focuses on fruit production. Young shoots, leaves, tuberous roots and the single soft seed are also eaten in some cuisines, but they have different harvesting and preparation requirements. It does not cover other pear-shaped gourds or unrelated crops also called vegetable pear.

  Armenian Cucumber / Snake Melon

  Cucumis melo var. flexuosus

  Suitability for this climate: Recommended

  This profile covers Armenian cucumber and snake-melon cultivars grown vertically and harvested while immature as crisp, mild cucumber-like fruit. Despite the common name, Armenian cucumber is botanically a melon in the Flexuosus group of Cucumis melo rather than a true cucumber, Cucumis sativus. It includes pale green, dark green and striped long-fruited cultivars. It does not cover snake gourd, ordinary cucumber, mature sweet muskmelon, bitter melon or yardlong bean. Fruit is intended for immature harvest before the rind, flesh and seeds harden.

  Chilacayote / Fig-Leaf Gourd / Shark Fin Melon (Trellised)

  Cucurbita ficifolia

  Suitability for this climate: Recommended

  This profile covers Cucurbita ficifolia grown on a dedicated heavy structure for its edible mature fruit, young fruit, seeds or tender shoots. It is commonly called chilacayote, fig-leaf gourd, fig-leaf squash, Malabar gourd, seven-year melon or shark fin melon. It is distinct from ordinary pumpkin, winter squash, watermelon and wax gourd. Mature fruit can become large and heavy, so elevated vertical growing is specialist only. Fruit must be supported in a rigid cradle or allowed to rest on the ground or a platform.

  Climbing Lima Bean / Butter Bean / Madagascar Bean

  Phaseolus lunatus

  Suitability for this climate: Recommended

  This profile covers climbing forms of Phaseolus lunatus grown vertically for fresh shell beans or mature dry beans. It includes pole lima beans, climbing butter beans and long-lived tropical forms commonly sold as Madagascar beans. It does not cover bush lima beans, ordinary pole snap beans or other climbing bean species. Follow cultivar-specific guidance where maturity, day-length response or perennial behaviour differs. Phaseolus lunatus includes both annual and perennial forms. Most temperate garden cultivars are managed as annuals, while some tropical climbing forms may persist and crop for more than one season. This profile does not cover bush lima beans, common pole beans, scarlet runner beans or ornamental Phaseolus seed not sold as an edible cultivar. Lima-bean pods are normally shelled rather than eaten whole.

  Hyacinth Bean / Lablab Bean

  Lablab purpureus

  Suitability for this climate: Recommended

  This profile covers edible cultivars of Lablab purpureus grown vertically for cooked young pods, fresh shell beans or mature dry seed. It is also called hyacinth bean, lablab bean, Indian bean, field bean or sem. Lablab is a short-lived tropical perennial but is commonly cultivated as an annual vegetable or ornamental vine. Not every ornamental hyacinth-bean seed line is intended for food. Use a named edible cultivar and follow cultivar-specific preparation guidance. This profile does not cover common pole bean, lima bean, winged bean or jack bean.

  Passionfruit (Trellised)

  Passiflora edulis

  Suitability for this climate: Recommended

  This profile covers edible passionfruit cultivars and forms of Passiflora edulis grown on a permanent trellis for fruit production. It includes purple passionfruit and yellow passionfruit, often listed as P. edulis f. flavicarpa, together with cultivated hybrids derived mainly from them. It does not cover banana passionfruit, giant granadilla, sweet granadilla, maypop or ornamental Passiflora species. These crops differ in climate, pollination, fruit and weed risk. Purple and yellow forms differ in cold tolerance, disease response and pollination. Purple passionfruit is often self-compatible, while yellow forms and some cultivars may require pollen from a compatible second vine. Cultivar-specific pollination guidance should take priority.

  Rice Bean

  Vigna umbellata

  Suitability for this climate: Recommended

  This profile covers climbing or twining forms of rice bean (Vigna umbellata) trained vertically and grown mainly for their small edible dry seeds. It includes locally selected grain landraces also sold as ricebean or climbing mountain bean. It does not cover adzuki bean, mung bean, cowpea, yardlong bean or other Vigna species. Follow seed-source guidance because growth habit, flowering response and maturity can vary between landraces. Some forms are compact or scrambling rather than strongly climbing; choose a vining cultivar for a vertical garden. Traditional landraces may require days shorter than about 12 hours to flower and can remain vegetative under long days. It does not cover adzuki bean, mung bean, cowpea, yardlong bean or rice.

  Snake Gourd (Trellised)

  Trichosanthes cucumerina

  Suitability for this climate: Recommended

  This profile covers cultivated snake gourd grown vertically for its tender immature fruit. It primarily refers to the long-fruited cultivated form of Trichosanthes cucumerina, historically also listed as T. cucumerina var. anguina or T. anguina. It does not cover yardlong or snake bean, bottle gourd, bitter melon, pointed gourd or the small-fruited wild form of Trichosanthes cucumerina. Fruit shape and mature length vary greatly between compact and extra-long cultivars. Snake gourd is normally harvested while green and tender. Fully mature fruit becomes fibrous and changes towards orange or red and is outside the usual vegetable-harvest stage.

  Wax Gourd / Winter Melon / Fuzzy Melon (Trellised)

  Benincasa hispida

  Suitability for this climate: Recommended

  This profile covers Benincasa hispida grown vertically for either young fuzzy melon or mature wax gourd, also called winter melon. Young fruit is harvested while small, tender and hairy; mature fruit develops a harder rind and a pale waxy bloom and is used as a storage vegetable. It does not cover bottle gourd, luffa, watermelon or other crops called winter melon. Mature wax-gourd fruit can become extremely heavy, so vertical growing is restricted to smaller cultivars or fruit supported by an extra-heavy structure and individual cradle.

  Winged Bean

  Psophocarpus tetragonolobus

  Suitability for this climate: Recommended

  This profile covers cultivated winged bean (Psophocarpus tetragonolobus) grown vertically, primarily for its tender immature pods and young shoot tips. It is a frost-tender tropical climbing plant that may persist as a perennial in year-round warm climates but is commonly managed as an annual vegetable crop. It does not cover asparagus pea or winged pea (Lotus tetragonolobus), which is a separate, non-climbing Mediterranean species. Many traditional cultivars require short days to initiate flowering, while day-neutral cultivars flower more reliably outside equatorial regions. This profile does not cover yardlong bean, common pole bean, hyacinth bean, yam bean or sword bean. Mature seed and tuber production have different harvest and preparation requirements and are outside the main scope of this profile.
