Kudzu

Pueraria lobata

Kudzu is the notorious "vine that ate the South" - a semi-woody perennial vine from East Asia (accepted name Pueraria montana var. lobata; Pueraria lobata is the widely-used synonym) that is one of the most destructive invasive plants in North America. This is a do-NOT-plant entry, included only as a warning. In warm, humid climates a single vine can grow up to a foot a day and tens of feet in a season, twining over and SMOTHERING shrubs, fences, power poles, whole trees, and entire hillsides under a dense blanket of three-part leaves until everything beneath it is shaded out and killed. It spreads by deep tuberous roots, by stems that root wherever a node touches the ground, and by seed, making established infestations extraordinarily hard to eradicate. It is a listed noxious or invasive weed across much of the southeastern United States and is illegal to plant or sell in many states. There is no legitimate garden use case. Its late-summer flowers do feed bees, and its starchy roots and young leaves have a long food history in East Asia - but neither fact changes the answer: do not plant kudzu. For a vine on an arbor, fence, or trellis, plant a native climber instead - American wisteria (Wisteria frutescens), crossvine (Bignonia capreolata), or coral honeysuckle (Lonicera sempervirens).

Care tips

•

The only honest tip is do NOT plant kudzu - it is one of the most destructive invasive plants in North America and is illegal to plant or sell in many states.

•

For a vigorous vine on an arbor, fence, or trellis, plant a native climber instead: American wisteria (Wisteria frutescens), crossvine (Bignonia capreolata), or coral honeysuckle (Lonicera sempervirens).

•

If kudzu is already on a property, treat it as an eradication project, not a garden plant: cut or mow repeatedly through the growing season to starve the roots, dig or herbicide the root crowns over several years, and never compost or dump prunings (roots and stems re-root readily).

Lifecycle

Planting

Do not plant kudzu. It is a listed noxious or invasive weed across much of the southeastern US and is illegal to plant or sell in many states. It asks almost nothing - full sun and average soil - and that lack of demands is exactly the danger: anywhere it can reach unmanaged ground it will escape and take over. If you want a vine for sun, plant a native climber such as American wisteria (Wisteria frutescens), crossvine (Bignonia capreolata), or coral honeysuckle (Lonicera sempervirens) instead.

Transplanting

Kudzu re-establishes from the smallest scrap of root or rooted stem, so even fragments left in the soil or in dumped prunings will regrow. This is not a plant to move or share; it is a plant to contain and remove. Never relocate it, and never leave cut root crowns or stem pieces lying on the ground where they can re-root.

Early growth

Growth is alarmingly fast once roots take, needing no supplemental water after establishment in most of its range. The vigor that looks like easy cover in the first season is the same vigor that overtops and kills neighboring plants within a few seasons.

Maturity

A mature plant is a long-lived perennial vine with enormous, deep tuberous roots that store energy and resprout after cutting, mowing, or frost. At maturity it produces fragrant late-summer flowers and seed pods and blankets large areas, smothering and killing trees and shrubs beneath it and requiring years of repeated cutting plus herbicide to truly eradicate.

Propagation

Spreads aggressively by deep tuberous roots, by stems that root at the nodes wherever they touch soil, and by seed. This three-way reproductive vigor is the engine of its invasiveness - which is precisely why it must never be propagated or planted, and why control means destroying the root crowns, not just cutting the visible vines.

Musa acuminata

Banana

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.

Perennial

Full sun / Part shade

A vigorous, twining perennial vine grown for the papery green female cones (strobiles) that flavor and preserve beer. It dies to the ground each winter and races 15 to 20 feet up a trellis, arbor, or porch each season on rough, clinging stems with coarse, lobed leaves. Dioecious - only female plants bear the aromatic cones - and the North American native variety (var. lupuloides) is a larval host for Question Mark and Red Admiral butterflies.

Perennial

Full sun / Part sun / Part shade

A herbaceous, tuberous perennial vine of eastern North America that twines 8 to 16 feet up surrounding vegetation through moist thickets, bottomlands, marsh and streambank edges. From mid-summer into fall it carries fragrant, maroon-to-reddish-brown pea-like flowers in compact racemes from the leaf axils, followed by edible seeds; the underground tubers are an edible, protein-rich staple long gathered as Indian potato. A native legume and a documented larval host for the Silver-spotted Skipper, it spreads vigorously by seed and tubers.

Perennial

Full sun / Part sun / Part shade

A vigorous, fast-growing woody vine from China grown commercially worldwide for its fuzzy brown, edible fruits. It climbs 15 to 30 feet and can fill a 200 sq. ft. trellis in time, carrying large rounded leaves and slightly fragrant cream flowers that open on year-old wood in late spring. It is dioecious: a male pollinizer must be grown alongside female plants for fruit to set.

Perennial

Full sun / Part shade

A vigorous, evergreen, tendril-climbing vine from the subtropics of southern Brazil, Paraguay, and northern Argentina, grown both for its strikingly intricate purple-and-white flowers and for its edible passion fruit. The flower is a small work of engineering: a ring of white-and-purple petals beneath a fringed corona of wavy purple-banded filaments, with the five anthers and three stigmas held on a raised central column at exactly the height a large carpenter bee brushes as it forages. Where winters are frost-free (USDA zones 9b-11b) it is a fast, hard-climbing perennial that can blanket a sturdy trellis or fence in a single season and produces round, leathery purple or yellow fruits whose aromatic, seedy pulp is the fragrant passion fruit of juices and desserts. Two honest cautions matter: it is a frost-tender plant grown as an annual or under glass where colder, and the unripe fruit and the foliage contain cyanogenic compounds and are mildly toxic, so only fully ripe fruit should be eaten.

Bear's breeches is a bold Mediterranean perennial whose dramatically lobed, glossy leaves inspired the Corinthian column capital of classical architecture. Its wild native range spans the central and eastern Mediterranean - Italy, Sicily, Sardinia, the Balkans, Greece, the Aegean, Anatolia and the Levant, plus NW Africa (Morocco, Algeria, Tunisia); it is naturalised (not native) further west into Iberia. In gardens it serves as an architectural statement plant, producing tall white-and-purple flower spikes in summer on established clumps. The honest catch is its root system: fleshy, deep-running tuberous roots regenerate readily from the smallest fragment, making Acanthus mollis genuinely difficult to eradicate once established and a declared invasive in Australia and New Zealand, so site selection is a permanent decision.
