Invasive species

[edit]

P. tarminiana and P. tripartita thrive in the climate of New Zealand. They are invasive species since they can smother forest margins and forest regrowth. It is illegal to sell, cultivate, or distribute the plants.[3]

As of 2011, banana passionfruit vines are smothering more than 200 square miles (520 km2) of native forest on the islands of Hawaii and Kauai. Seeds are spread by feral pigs, birds and humans.[4][5] The vine can also be found all across the highlands of New Guinea and in Tasmania.[citation needed]

Banana passionfruit (Passiflora tripartita var. mollissima, also known as Passiflora mollissima) is an evergreen climbing vine in the family, native to the Andean highlands of western , where it grows as a fast-growing producing oblong, fruits up to 12 cm long with leathery skin, gelatinous orange pulp, and numerous small black seeds. Originating from elevations of 1,800–3,600 meters in countries including , , , , and , the plant has been cultivated since pre-Columbian times for its edible fruits and ornamental pinkish-white flowers. It thrives in subtropical to temperate climates with annual rainfall exceeding 800 mm, preferring humus-rich, well-drained soils at temperatures between 13–18°C, though it tolerates ranges from 8–30°C and can climb up to 20 meters using coiling tendrils. A single mature vine can yield 150–400 fruits per year after two years of growth, with fruits ripening year-round in tropical regions and peaking in spring to fall. The fruits are prized for their tangy-sweet, aromatic pulp, which is rich in vitamins A and C, , antioxidants like (478.9 mg/100 g dry weight) and (81.6 μg/g dry weight), as well as minerals such as calcium, iron, , and . Nutritionally, the pulp exhibits high capacity, with values of 50.1 mM equivalents/100 g and ORAC values of 105.2 mM /100 g, contributing to potential and bone-protective health benefits. Culinary uses include eating the fresh pulp, incorporating it into juices, smoothies, salads, desserts, ice creams, pies, and jams, often paired with tropical fruits or . While widely grown for food and as an ornamental in suitable climates, banana passionfruit can become invasive outside its native range, forming dense thickets that smother native vegetation and reduce biodiversity, particularly in where control measures such as physical removal or herbicides are recommended. It is sometimes confused with the closely related , which is invasive in . Vines are propagated easily from seeds or cuttings.

Taxonomy and Description

Taxonomy

Banana passionfruit is scientifically classified as Coppens d'Eeckenbrugge, V.E. Barney, P.M. Jørgensen & J.M. MacDougal, a formally described in 2001 as a new cultivated within the genus L. (Passifloraceae). The name honors the Tarmin family, early cultivators of the species in . It is placed in the Tacsonia (Juss.) Holub, a group characterized by with tubular corollas adapted for and often cultivated for their edible fruits in the Andean region. Within this , P. tarminiana is distinguished from related taxa by specific morphological features, such as small, acicular, stipules (4–7 mm long) and reflexed, light pink petals and sepals forming a wider chamber. Historically, P. tarminiana was frequently confused with Passiflora tripartita (Juss.) Poir. var. mollissima (Kunth) Holm-Nielsen & P.M. Jørg. and the misapplied name Passiflora mollissima Kunth, leading to erroneous identifications in horticultural and botanical literature prior to 2001. This confusion arose from superficial similarities in fruit shape and climbing habit, but reclassification as a distinct was based on morphological differences—like the absence of dense pubescence on young stems and leaves in P. tarminiana compared to the campanulate corolla and persistent stipules in P. tripartita var. mollissima—as well as genetic evidence from , RAPD, and cpDNA analyses showing clear separation from P. tripartita var. mollissima, P. mixta L.f., and P. cumbalensis (Kunth) L.H. Bailey. Accepted synonyms include Passiflora mollissima (in part, misapplied) and Passiflora tripartita var. mollissima, reflecting the prior taxonomic lumping of what are now recognized as separate entities.

Botanical Description

Banana passionfruit (Passiflora tarminiana) is an evergreen, high-climbing liana that can reach lengths of 5–15 meters, scrambling or clambering over vegetation with the aid of coiling tendrils. The stems are cylindrical with fibrous bark, internodes 6–12 cm long, and covered in a soft, canescent indumentum. The leaves are tripartite, three-lobed, measuring 7–29 cm wide overall, with ovate to acuminate lobes and serrate margins; the central lobe is 5.5–16 cm long and 2.5–8 cm wide, lateral lobes 5–16 cm long and 2.3–7 cm wide. The upper surface is moderately lustrous and scarcely pubescent, while the undersurface is canescent-pubescent with ferrugineous trichomes along the nerves; the petiole is 3–7 cm long. Stipules are auricular and aristate, 4–7 mm long and 2–3 mm wide with a 3–4 mm arista, and early . Flowers are pendulous, solitary, and axillary, with peduncles 3–10 cm long and a of 6–8 cm. They feature five bright pink oblong sepals (4.5–6 cm long and 1.2–2.5 cm wide) and five light pink petals slightly shorter (reflexed), surrounding a tube 6–8 cm long and 0.7–1 cm wide; the corona includes white knobs. Blooming occurs in suitable climates year-round. The fruits are berries, 10–14 cm long and 3.5–4.5 cm wide, initially dark green with white dots and softly pubescent, turning yellow to orange-yellow when ripe. Inside, they contain numerous black seeds enveloped in an edible, aromatic orange with a tangy flavor; fruits typically ripen 70–80 days after . The flower morphology supports self-compatibility, with exposed stamens facilitating cross-pollination by or autogamous .

Native Range

Banana passionfruit (Passiflora tripartita var. mollissima) is native to the Andean regions of , encompassing , , , , and . In its native range, the species thrives at altitudes between 2000 and 3000 meters in tropical uplands, where it benefits from moderate annual rainfall of 1000–2000 mm and temperatures ranging from 15–25°C. The plant occupies montane forests, forest edges, and disturbed areas within these highland ecosystems, often integrating into hummingbird-pollinated communities where species like the Andean swordbill (Ensifera ensifera) serve as primary pollinators.

Introduced Ranges

Banana passionfruit ( tripartita var. mollissima) was introduced to in the 1850s for its ornamental value and edible fruit, and it has since become widespread across the , particularly in coastal and lowland areas. The species has also been introduced to southeastern Australia, including regions in , Victoria, , and , often escaping from gardens into natural areas. It is present in , where it has naturalized in some areas, as well as in parts of such as . It is also naturalized in and . During the , banana passionfruit gained popularity as a subtropical fruit crop in various regions, leading to its escape from cultivation sites into wild habitats. Its establishment in non-native ranges is facilitated by high viability, which allows long-term persistence in banks, and the ability to propagate vegetatively from stem fragments. In places like , these traits have contributed to its invasive spread, where it smothers native vegetation.

Ecology and Reproduction

Growth and Reproduction

Banana passionfruit (Passiflora tripartita var. mollissima) is a rapid-growing climber that typically reaches maturity and begins fruiting 10-12 months after in its native , with continuous production thereafter in frost-free environments. The plant exhibits vigorous vegetative growth, particularly during the when flowering peaks, allowing it to ascend supports or trees quickly. In cultivation, individual plants have a lifespan of up to 10-15 years, though wild specimens may persist longer, potentially exceeding 20 years under favorable conditions. Reproduction occurs primarily through seeds, with each elongated fruit containing 50-200 small, hard-coated that are dispersed by birds, mammals, or . Vegetative is also common, achieved via stem cuttings that root readily to produce genetically identical clones. The species is self-compatible, enabling both and cross-pollination, though fruit set is higher with cross-pollination (29.5% versus 17.5% for selfed flowers). In its native Andean range, is primarily facilitated by hummingbirds, which are attracted to the large flowers featuring an elongated nectar-producing floral tube (8-9.5 cm long); in introduced regions, bees such as honeybees (Apis mellifera) and bumblebees (Bombus spp.) serve as effective pollinators. Flowers remain open for about one week, with buds maturing two days prior to . Seed requires pretreatment, such as mechanical to remove the hard seed coat and , or passage through an animal's digestive tract to break ; without such treatment, is delayed and rates are low. typically begins 9 days after under optimal conditions (20-30°C ), with 50% of viable seeds emerging within one month, though full may take 6 weeks to 6 months or longer. Seeds maintain high viability, averaging 74% viability, and can remain yet viable for several years due to their prolonged natural .

Ecological Interactions

Banana passionfruit (Passiflora tripartita var. mollissima) exhibits notable environmental tolerances that contribute to its adaptability across ecosystems. It is shade-tolerant, particularly in dappled or partial shade, where it shows and rapid height growth, though it prefers full sun for optimal development. Once established, the plant demonstrates drought resistance, enabling survival in drier conditions typical of montane habitats. It thrives in a wide range of 5.5–7.5, accommodating mildly acidic to neutral conditions. In its native Andean range, banana passionfruit engages in mutualistic interactions with local wildlife. Its flowers provide that attracts hummingbirds, which serve as primary pollinators by accessing the floral structures. The elongated fruits are consumed by various frugivorous animals, facilitating while supporting wildlife nutrition in montane forests. As a vigorous climber, banana passionfruit exerts competitive effects on surrounding in invaded ecosystems. Its dense foliage forms mats that smother plants by blocking , preventing establishment and natural regeneration. The plant's prolific growth and decaying litter also alter soil nutrient dynamics, influencing microbial communities and potentially favoring further invasion over . In non-native regions, of banana passionfruit is aided by introduced animals. In , feral pigs (Sus scrofa) consume and excrete viable seeds, promoting short-distance spread and establishment in disturbed areas. In , birds contribute to dispersal, alongside possums, enhancing the plant's invasiveness. The invasion by banana passionfruit significantly impacts in forested ecosystems. By overgrowing and native , it reduces plant diversity, disrupts forest structure, and hinders the regeneration of endemic species, ultimately altering suitability for associated .

Cultivation and Uses

Cultivation Practices

Banana passionfruit ( tripartita var. mollissima) is suited to subtropical and temperate climates, thriving in regions with average daytime temperatures of 15–18°C and tolerating a range of 8–30°C. It is frost-sensitive, with young growth damaged below -2°C, though mature dormant can survive down to -5°C. Ideal conditions include annual rainfall of 1,300–1,700 mm, though it tolerates 700–2,300 mm, and it performs best at elevations above 1,000 m in tropical areas or lower in subtropical and temperate zones. The plant prefers humus-rich, moist, well-drained loamy or clay soils with a of 6–7, tolerating a broader range of 4.3–8. Propagation occurs via seeds or cuttings; fresh seeds can be sown directly with pulp intact, while stored seeds require soaking for 24 hours and germination at 19–24°C, which may take up to 12 months. Cuttings from young shoots at nodes root readily, and layering, including air layering, is also effective. Plants are spaced 3–4 m apart and trained on sturdy trellises to support their vigorous growth up to 8–10 m. Ongoing care involves maintaining consistent moisture without waterlogging, providing full sun or semi-shade, and applying moderate fertilization to support growth. is well-tolerated; vines can be cut back to ground level if needed, with formation guiding stems to trellises to promote branching and fruit production. Fruits are harvested when fully yellow and slightly soft, typically year-round in suitable climates. Mature vines, reaching full production after 2 years from , can yield 300–400 fruits annually, equivalent to 20–30 kg per vine under good management, with commercial densities achieving around 10–15 tonnes per . Common challenges include susceptibility to and spider mites, which feed on leaves and stems, as well as fungal diseases such as (also known as collar rot), causing wilting and plant death in poorly drained conditions. Anthracnose may also affect fruits, leading to black spots and deformation.

Culinary and Other Uses

The fruit of banana passionfruit (Passiflora tripartita var. mollissima) is typically consumed fresh, with only the gelatinous being edible while the black seeds are inedible and usually discarded. The pulp's mild, tangy flavor makes it suitable for juicing into beverages, as well as incorporation into desserts such as pies, jams, and sorbets. In Andean cuisine, it features prominently in nectars, yogurts, and functional drinks, valued for its refreshing taste and versatility in food preparations. Nutritionally, the fruit is rich in , providing approximately 77 mg per 100 g of pulp, and , supporting digestive health and immune function. It also contains at levels of 16 mg per 100 g dry pulp, along with that contribute to its high capacity, measured at 50.12 mmol equivalents per 100 g dry weight via DPPH assay. These compounds help scavenge free radicals, potentially reducing , though the fruit offers moderate calories, carbohydrates, and protein overall. Beyond culinary applications, banana passionfruit is cultivated as an in gardens for its showy pink flowers and lush, tripartite foliage, particularly in subtropical or temperate regions where its vigorous habit adds aesthetic value without aggressive invasiveness. The vine serves as a hardy for other Passiflora species, enhancing cold tolerance and disease resistance in commercial and home settings. In native Andean communities, traditional uses include remedies for digestive issues like digestion support, with limited scientific evidence indicating anti-inflammatory and hepatoprotective effects from its bioactive compounds. Commercially, it ranks among the most important Passiflora crops in , especially in the , where it is widely grown for local markets and home consumption after the purple passionfruit (P. edulis).

Invasive Status and Management

Regions of Invasiveness

Banana passionfruit (, synonyms Passiflora tripartita var. mollissima and Passiflora mollissima), also known as banana poka, has established invasive populations in several tropical and subtropical regions, where it aggressively climbs and smothers native vegetation, leading to significant ecological disruption. In , it infests approximately 520 km² (as of 1986) of native forests across the islands of Hawaiʻi, Kauaʻi, and , forming dense mats that block sunlight and suppress understory growth, thereby reducing and altering forest structure by outcompeting native plants for resources. It is listed as a in the state, highlighting its severe threat to endemic ecosystems. In , banana passionfruit invades native forest remnants on the , where it climbs trees and shrubs, smothering canopies and facilitating further invasion by reducing native plant vigor and diversity. Its sale, propagation, and distribution have been prohibited nationwide under the National Pest Plant Accord since 2012, reflecting its status as a high-risk environmental weed. Regional councils, such as , enforce these bans and monitor infestations to prevent spread into undisturbed forests. Australia faces moderate threats from banana passionfruit as an environmental weed in southeastern states including , Victoria, and , where it naturalizes in disturbed areas and rainforests, climbing over native vegetation and contributing to habitat degradation through competition and structural changes. It is not declared noxious federally but is managed locally due to its potential to reduce native in coastal and forested habitats. Emerging invasive issues have been noted in , where it is classified as a Category 1 invader, prohibiting its cultivation and trade, as it invades forests and outcompetes indigenous flora, leading to . In parts of , sporadic reports indicate its potential to become problematic in tropical forests, though widespread invasions remain limited. Overall, banana passionfruit does not establish invasively in cooler climates, such as temperate regions of , due to insufficient warmth for vigorous growth and reproduction.

Control Methods

Managing banana passionfruit (, synonyms Passiflora tripartita var. mollissima and Passiflora mollissima), an invasive vine, requires targeted strategies to prevent regrowth and dispersal in affected ecosystems. Effective control often involves a combination of mechanical, chemical, and biological methods, tailored to site conditions and scale, with ongoing monitoring essential due to the plant's resilience. Mechanical control focuses on physical removal to eliminate plants and reduce seed production. Cutting vines near the base and digging out is recommended for small infestations, as stems rarely resprout but may require repeated efforts to address regrowth from remaining root fragments. In , pulling up and disposing of stems by hanging them to prevent layering is a common practice, particularly effective before fruiting to limit seed spread. This method is labor-intensive but suitable for accessible areas without desirable vegetation nearby. Chemical control employs herbicides to target foliage or stumps for broader or inaccessible infestations. at 5% dilution applied to cut stumps effectively kills roots without harming surrounding , while (e.g., Garlon 3A) at undiluted or 50% concentrations is used for foliar spraying or aerial application on mature vines. In , options include metsulfuron (1g/L water), (100ml/L), or (200ml/L) for cut-stump treatment, with spraying best in spring to autumn using additives like penetrants for better absorption. These applications must follow label guidelines to minimize non-target impacts. Biological control has been explored through introduced agents, though with limited success to date. In , the fungus passiflorae was released in 1996 to cause disease, showing pathogenicity in trials but mixed field results against banana passionfruit. Insects such as the moth Cyanotricha necyrina (released 1989) and the passion butterfly Agraulis vanillae (1970s) have been tested, but establishment and impact remain low. Other candidates like Fusarium oxysporum f. sp. passiflorae and fungi are under evaluation, highlighting the challenges in achieving widespread suppression. Integrated approaches combine these methods with monitoring and community involvement for . In , mechanical cutting followed by application targets outliers and roadsides, supported by public programs involving groups like the and state agencies for large-scale efforts. employs similar combinations through regional councils and volunteer initiatives, such as Weed Action's removal programs, emphasizing follow-up treatments three times yearly and containment in high-risk districts like and . These strategies promote native regeneration post-control. A key challenge is the longevity of the , with dormant seeds dispersed by birds, pigs, possums, and rats persisting in and enabling reinvasion despite initial control success. Long-term efforts, often spanning years, are necessary to deplete this through repeated interventions and preventing new introductions via or fruit.
