Summary of Invasiveness
Top of pageT. spathacea is a succulent herb commercially grown for bedding, rock gardens, and tropical effects, but classified in the Global Compendium of Weeds as an invasive species and an environmental weed (Randall, 2012). This species has escaped into natural areas from gardens and yards where it has been planted as an ornamental (ISSG, 2012; PIER, 2012). T. spathacea spreads by seeds, which are dispersed by wind and it also grows from cuttings and plant fragments (Langeland and Burks, 2008). Once established, it is able to grow forming dense groundcover on the forest floor preventing the germination and establishment of native plants (ISSG, 2012). T. spathacea is listed as an invasive species Category II in Florida (Florida Exotic Pest Plant Council, 2011), and it is also considered invasive in Cuba, Puerto Rico and the Virgin Islands (González-Torres et al., 2012; Acevedo-Rodríguez and Strong, 2012) and the Pacific Islands.

Notes on Taxonomy and Nomenclature
Top of page
The family Commelinaceae includes 40 genera and 652 species widely distributed in tropical and temperate regions (Stevens, 2012). Member of this family are herbs with relatively soft and fleshy leaves. Commelinaceae is a family of plants diverse in both the Old World tropics and the New World tropics, with some genera distributed in both (Faden, 1983; Evans et al., 2003). The species within this family exhibit remarkable morphological variation, particularly in floral and inflorescence traits (Evans et al., 2000; Faden, 2000). Studies suggest that this family has radiated extensively in response to non-nectar seeking pollinators with changes in floral symmetry, stamen number, structure, and position, and inflorescence size and arrangement (Faden, 2000; Evans et al., 2003).
The genus Tradescantia is native to the New World tropics and includes about 70 species distributed from Canada to northern Argentina (USDA-ARS, 2012). Many species within this genus are valuable plants used as ornamentals and houseplants. Most of the cultivars commercialized in nurseries and commonly grown in garden are of complex hybrid origin, derived from crosses between natural species (Anderson and Hubricht, 1938).
Description
Top of pageErect perennial sub-succulent herb with short stout erect stems up to 20 cm tall, often clustered and forming large colonies. Leaves imbricate, crowded, linear-lanceolate to oblong-lanceolate, 20 - 35 cm long, mostly 3 - 5 cm broad, acuminate at the apex, scarcely narrowed at base above the sheath, usually dark green above, reddish-purple beneath. Inflorescences axillary; peduncles 2 - 4.5 cm long, simple or branched; bracts deeply boat-shaped, broadly ovate, 2 - 4.5 cm long, 2.5 - 5 cm broad. Flowers numerous, small, white, clustered within a folded, boat shaped bract (spathe) 3 - 4 cm long, short-stalked from leaf axils; petals 3, white, broadly ovate, stamens 6 with hairy filaments. Fruit capsular, with a seed per locule; seeds oblong-ellipsoid with linear hilum (Acevedo-Rodríguez and Strong, 2005; Richard and Ramey, 2007).
Distribution
Top of pageT. spathacea is native to southern Mexico and Central America (Guatemala and Belize; Govaerts, 2012; USDA-ARS, 2012). It has been introduced as an ornamental and houseplant in many tropical regions including China, Japan, Africa, southeast Asia (Govaerts, 2012), USA (Florida, Louisiana, and Hawaii; USDA-ARS, 2012), the West Indies (Acevedo-Rodríguez and Strong, 2012), Australia (Queensland Department of Primary Industries and Fisheries, 2011), and the Pacific islands (PIER, 2012).

History of Introduction and Spread
Top of pageT. spathacea was introduced into the West Indies as an ornamental and houseplant probably during the nineteenth century. By 1883, D. Bello reported this species for the island of Puerto Rico (Bello, 1883). Later, Ignaz Urban in his Symbolae Antillanae (IV: 147, 1903-1911) reported this species growing in gardens and forests for Puerto Rico, Cuba, Hispaniola, St. Thomas, St. Croix, Guadeloupe, Martinique, and St. Vincent (Urban, 1905). In 1920, T. spathacea is reported for the Bahamas by N.L. Britton and C.F. Millspaugh (Britton and Milsspaugh, 1920).
T. spathacea was also introduced in Florida as an ornamental and by 1933 it was reported as naturalized in cultivated grounds and pinelands in peninsular Florida by J.K. Small (Small, 1933). Currently, this species is included in the Florida List of Invasive species as an invasive plant Category II, which are invasive plants that have increased in abundance or frequency but have not yet altered natural plant communities (Florida Exotic Pest Plant Council, 2011).
T. spathacea was also introduced in the nineteenth century on islands in the Pacific, including Hawaii, Guam, Fiji, French Polynesia, Cook Islands, Mariana Islands, and Micronesia (see distribution table for details; PIER, 2012). By 1924, it was reported as “naturalized” on American Samoa (Setchell, 1924) and later it was reported as “common and naturalized” on Tonga (Yuncker, 1959), Niue (Sykes, 1970), and Fiji (Smith, 1979). Currently, T. spathacea is considered an invasive species that is threatening ecosystems on the Pacific islands and regular monitoring is recommended wherever it is present (PIER, 2012).
Risk of Introduction
Top of pageT. spathacea is widely commercialized in the nursery and landscape trade as an ornamental and houseplant (ISSG, 2012). In addition, T. spathacea can be dispersed by seeds, by cuttings and by plant fragments that rapidly colonize areas where it grows (Richard and Ramey, 2007). Seeds are dispersed by wind, facilitating long-distance invasions (Langeland and Burks, 2008). Consequently, the probability of this species invading and colonizing new habitats remains high.
Habitat
Top of pageT. spathacea is commonly used as an ornamental plant and has been planted in gardens and yards from where it has escaped. Currently, it can be found growing in the understory of coastal forests, shrublands, pinelands, hammocks, secondary forests, cultivated grounds, and disturbed areas from sea level to low elevations. In these habitats, T. spathacea grows forming a dense ground cover (Richard and Ramey, 2007; Langeland and Burks, 2008, ISSG, 2012). On islands in the Pacific, the species often grows on stone or coral walls and on rocky cliffs (Smith, 1979; PIER, 2012).

Biology and Ecology
Top of pageGenetics
T. spathacea is a diploid species with 2n = 12 chromosomes. As in other diploid species, its karyotype is considered to consist of two genomes, which in the case of this species have been designated as α and β complexes (Golczyk and Joachimiak, 1999).
Reproductive Biology
Flowers in T. spathacea are hermaphroditic, small and white. Flowers are visited and pollinated by insects. The reproductive strategy in this species includes both cross-pollination, and self-pollination in the absence of pollinators (Zomlefer, 1983).
Physiology and Phenology
T. spathacea produces flowers and fruits throughout the year in locations within and outside its native distribution range (Langeland and Burks, 2008; ISSG, 2012, PIER, 2012).
Environmental Requirements
T. spathacea prefers to grow in tropical and subtropical areas with warm temperatures ranging from 14°C to 27°C (Langeland and Burks, 2008). It is a heat tolerant species, but it is easily damaged by frost and winter conditions. T. spathacea is able to grow in full sun to moderate shade in the floor of the understory. It is adapted to grow on a wide range of well-drained soil types including rocky soils, sand, and limestone bedrock (Smith, 1979; ISSG, 2012). It does not tolerate water logged soils. T. spathacea can be found growing as an epiphytic or semi-epiphytic plant on palm or tree trunks, rocky cliffs or other niches with essentially no soil (Smith, 1979).

Environmental Impact
Top of pageT. spathacea is a successful invader that can escape from gardens and is able to colonize disturbed areas as well as natural forests. This species grows in the understory of the forest and once established, it is able to rapidly replace the native vegetation of this forest stratum. T. spathacea grows forming a dense ground cover and thickets preventing the germination and establishment of seedlings of native plants (Richard and Ramey, 2007; Langeland and Burks, 2008; ISSG, 2012). Floridata reports that ecological problems in Florida particularly occur in hardwood hammock forests.
Social Impact
Top of pageIn humans, T. spathacea can cause stinging, itching, and rash from contact with the surface of leaves and sap or from contact with the astringent juice produced when leaves are bruised (Morton, 1982). The species can be poisonous in large quantities if swallowed. There are also reports of effects on pets, particularly dogs that have developed severe allergies. Ingestion of the plant may cause irritation of the lips, mouth, throat and abdominal pain in animals and humans (Morton, 1982).

Similarities to Other Species/Conditions
Top of pageT. spathacea can be easily distinguished from other Tradescantia species by its elongated leaves (green above, purple below) forming a sub-rosette and by having white petals.
Prevention and Control
Top of pageDue to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.
Prevention
Plant cuttings should not be dumped anywhere as this is a frequent source of new weed infestations. The origin of new topsoil or fill should be checked as physical transportation of plant segments in soil is a major method of spread (ISSG, 2012).
Mechanical Control
Plants and smaller patches of T. spathacea may be hand pulled up and removed from treated areas, but all roots and plant fragments must be removed in order to avoid resprouts.
Chemical Control
In Florida, experts have recommended foliar treatment with 3-10% triclopyr in water or oil applied to buds, or 2% glyphosate (Florida Exotic Pest Plant Council, 2011).
