Duranta erecta

Duranta erecta is a species of flowering shrub in the verbena family Verbenaceae, native from Mexico to South America and the Caribbean. It is widely cultivated as an ornamental plant in tropical and subtropical gardens throughout the world, and has become naturalized in many places. It is considered an invasive species in Australia, Southasia,China, South Africa and on several Pacific Islands. Common names include golden dewdrop, pigeon berry, and skyflower.

Description
Duranta erecta

Duranta erecta is a sprawling shrub or (infrequently) a small tree. It can grow to 6 m (20 ft) tall and can spread to an equal width. Mature specimens possess axillary thorns, which are often absent on younger specimens. The leaves are light green, elliptic to ovate, opposite, and grow up to 7.5 cm (3.0 in) long and 3.5 cm (1.4 in) broad, with a 1.5 cm petiole. The flowers are light-blue or lavender, produced in tight clusters located on terminal and axillary stems, blooming almost all year long. The fruit is a small globose yellow or orange berry, up to 11 mm (0.43 in) diameter and containing several seeds.[1] The leaves and unripened berries of the plant are toxic, and are confirmed to have killed children, dogs and cats.[2] However, songbirds eat the fruit without ill effects.[3]

Taxonomy

The genus name is in honor of Castore Durante, a fifteenth-century Italian botanist.[4] The specific epithet erecta means "upright" in Latin. The plant is also known as D. repens, from the Latin for "creeping". The latter name was originally used to identify smaller-leaved varieties of the species.[5]

Ecology
Duranta erecta

Duranta erecta is native to the Americas, from Mexico and the Caribbean south to Brazil and Argentina. There is some debate about whether the plant is also native to the southern United States, in Florida, Louisiana, Texas, Arizona and California, or is an introduced species there.[6] In its natural state, it commonly grows in rocky or sandy coastal areas with full sun, or moister, disturbed sites inland. Prior to maturity, the plant will grow at a rate of up to half a meter per year.

Cultivation

Golden dewdrop is widely grown as an ornamental plant throughout tropical and warm subtropical regions.[3] Its showy flowers and fruit make it a desirable addition to gardens, and the blossoms attract butterflies and hummingbirds.[3] There are a wide variety of cultivars available, including 'Alba', 'Aurea', 'Aussie Gold', 'Gold Mound', 'Geisha Girl', 'Sapphire Showers', and 'Variegata'.[7]

Invasive potential

The plant has been identified as an environmental weed in Australia, South Africa, and China,[8] and is described as invasive in Hawaii, Fiji and French Polynesia.[9] It has been introduced to other habitats but has not become invasive.

Research

Antioxidative coumarinolignoids called repenins have been isolated from Duranta erecta.[10]
