What Are Exotic Edible Plants?
Exotic edibles are plants from the tropics and subtropics that produce something you can eat or drink: fruit, leaves, spice, or tea. Many of the crops behind everyday staples, from coffee and chocolate to black pepper and turmeric, make fascinating houseplants in their own right. Growing them at home connects you to the origin of your food and rewards you with foliage you will not find in a supermarket aisle.
Fruit You Can Grow at Home
Start with the classics. Passion Fruit fruits reliably in a UK conservatory or sheltered garden, while Dragon Fruit Cactus is a low fuss climbing cactus that produces spectacular night blooms before setting fruit. For something hardier, Golden Kiwi and Pomegranate both cope with British winters given a sunny, sheltered spot.
Grow Your Own Spice Rack
Some of the most rewarding exotic edibles are spices. Turmeric and Galangal grow from rhizomes you can harvest and replant each year. Variegated Black Pepper is the true peppercorn vine in a striking variegated form, and Wild Betel produces the aromatic leaves used to wrap Thai and Vietnamese street food.
Tea, Coffee and Chocolate from Your Windowsill
Coffea arabica is a glossy, easy going houseplant that can genuinely produce coffee cherries with enough light and patience. Cacao is the chocolate tree itself, a true collector piece. For the kettle, Hibiscus sabdariffa gives you the deep red roselle calyces used in hibiscus tea, and Gynostemma pentaphyllum, known as jiaogulan or the herb of immortality, brews into a sweet herbal tea.
Hardy Exotic Edibles for the Garden
You do not need a greenhouse for everything. Musa basjoo is the famously hardy banana that survives UK winters outdoors. Feijoa produces aromatic pineapple guava fruit on an evergreen shrub, White Mulberry gives sweet berries on a handsome large leaved tree, and Fig 'Del Portogallo' ripens reliably against a warm wall.
