Bay laurel

A giant herbaceous perennial from Southeast Asia and the principal wild ancestor of most cultivated dessert bananas. What looks like a trunk is a 'pseudostem' - tightly rolled leaf sheaths - topped by a fountain of huge, paddle-shaped leaves that can run 6 to 10 feet long, giving an instant tropical effect. In frost-free climates (USDA zones 10a-11b) an established clump produces a drooping flower spike and a hanging bunch of edible fruit, then that pseudostem dies and is replaced by a sucker from the base. It is frost-tender: everywhere colder it is grown as a bold container or greenhouse foliage plant that is overwintered indoors and rarely, if ever, fruits.

Camellia sinensis is the evergreen shrub whose leaves, buds, and stems yield every style of tea - white, green, oolong, and black - and it is native to the monsoon-forest borderlands of SW China, Myanmar, northeast India, and mainland Southeast Asia. In gardens outside zones 7–9 it is too frost-tender to grow unprotected outdoors, and the honest catch is its unyielding demand for reliably moist, acid soil (pH 4.5–6.5): on anything alkaline or prone to summer drought it yellows, stalls, and refuses to thrive no matter how warm the climate.

A broadleaf-evergreen citrus tree reaching 15 to 30 feet tall and wide, with glossy foliage, sharp thorns on its twigs, and highly fragrant white four-petaled flowers. The large fruit (over 3 inches across) ripens pale yellow, often patched with pink, over juicy flesh that ranges from near-white to deep red by cultivar. A subtropical tree hardy only to USDA zone 9a, it is grown outdoors across the citrus belt and as an overwintered container plant farther north.

Citrus reticulata is the mandarin orange, a small evergreen citrus tree originating from wild populations in South China and Vietnam (the Nanling Mountains region), where domestication occurred at least twice from distinct wild subspecies. In warm climates (USDA zones 9-11) it is a productive, fragrant garden tree bearing the familiar loose-skinned sweet fruits prized worldwide. The honest catch is frost-tenderness: even a light freeze damages the tree and kills young growth, so outside the deep South, coastal California, and Mediterranean climates, it can only be grown as a container plant brought indoors each winter -- a significant maintenance commitment that most gardeners underestimate.

A small native tree with white spring flowers, edible summer berries, and copper to red fall color.

Chocolate vine is a vigorous, twining woody climber native to China, Japan, and Korea, producing clusters of spice-scented purple-maroon flowers in spring and large sausage-shaped fruits in autumn. It adapts readily to most well-drained soils in sun or part-shade and covers structures fast, making it a striking focal-point plant for walls, fences, and pergolas. The honest catch is its invasive potential: it smothers native shrubs and trees by blocking sunlight and is listed as invasive across much of the US East Coast and the Pacific Northwest, so it must not be planted where it can escape into natural areas, and annual hard pruning is essential to keep it under control.
