Clerodendrum quadriloculare (known as the bronze-leaved clerodendrum, fireworks plant, [3] [4] Philippine glorybower, shooting star or starburst bush [4] in English, and bagawak or bagawak morado [3] [4] in Filipino) is a species of flowering plant native to New Guinea and the Philippines. It is one of many species previously included in the family Verbenaceae, but transferred to the Lamiaceae based on molecular studies. [5] [6] [7] [8] The plants produce flowers which look good in a garden, but it can be difficult to eradicate.

Description

The bronze-leaved clerodendrum is a medium to large-sized shrub growing to a height of about 5 m (16 ft). The branches and twigs are four-sided. The leaves are in opposite pairs and are borne on medium-length petioles. The leaf blades are oblong and up to 20 cm (8 in) long, the upper surface being green and the underside purple; they have rounded bases, wavy margins and pointed tips. The showy flower clusters are borne at the tips of the shoots. Each contains many flowers with slender pink tubes about 7 cm (3 in) long, each terminated by five slender white, reflexed corolla lobes about 1.5 cm (0.6 in) long. The flowers are followed by ellipsoid, capsules containing four seeds. [9] The corolla tubes are exceptionally long and require specialist pollinators. [10]

Distribution and habitat

The bronze-leaved clerodendrum is native to the Philippines and Papua New Guinea, and has also been recorded from American Samoa, the Federated States of Micronesia, Fiji, French Polynesia, Guam, the Marshall Islands, the Northern Mariana Islands, Palau and Samoa, as well as Puerto Rico, [9] Singapore, and Hawaii. As well as parks and gardens, it is found on road verges and on disturbed ground, pastures, forest edges and undisturbed forests where it is able to displace native species. [10]

Invasiveness

The bronze-leaved clerodendrum is grown as an ornamental shrub but it has become naturalised in many locations, in some of which it is viewed as an invasive species. [9] It is a vigorous, rapid-growing shrub which sends up suckers which may develop into thickets. Additionally, cuttings and pieces of detached roots are easily moved with soil and can develop into new plants, and the seeds, which germinate readily, are spread by animals and birds in their droppings. [9] This shrub can grow in full sun, partial shade and deep shade, and in some locations grows as a dense, mono-specific ground cover layer under the forest canopy. [10]

Lamiaceae Family of flowering plants that includes sage and mint

The Lamiaceae or Labiatae are a family of flowering plants commonly known as the mint or deadnettle or sage family. Many of the plants are aromatic in all parts and include widely used culinary herbs like basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla, as well as other medicinal herbs such as catnip, salvia, bee balm, wild dagga, and oriental motherwort. Some species are shrubs, trees, or, rarely, vines. Many members of the family are widely cultivated, not only for their aromatic qualities, but also their ease of cultivation, since they are readily propagated by stem cuttings. Besides those grown for their edible leaves, some are grown for decorative foliage. Others are grown for seed, such as Salvia hispanica (chia), or for their edible tubers, such as Plectranthus edulis, Plectranthus esculentus, Plectranthus rotundifolius, and Stachys affinis. Many are also grown ornamentally, notably coleus, Plectranthus, and many Salvia species and hybrids.

<i>Vitex rotundifolia</i> Species of vine

Vitex rotundifolia, the roundleaf chastetree or beach vitex, is a species of flowering plant in the sage family Lamiaceae. It is native to seashores throughout the Pacific. Its range includes continents and islands stretching from India east to Hawaii and from Korea south to Australia. This shrub typically grows approximately 1 m in height. It has a sprawling growth habit and produces runners that root regularly at nodes. This rooting pattern allows the plant to spread rapidly. At maturity, V. rotundifolia produces blue-purple flowers that are borne in clusters and ultimately yield small brown-black fruits. Its leaves are rounded at the tips with green upper surfaces and silver lower surfaces. While the plant is a seashore obligate, it grows over a wide latitude range. It has been used for medicinal purposes throughout its native range. More recently, it was imported to the eastern United States where it has become a seashore invasive. Control efforts are presently underway to protect the fragile beach dune ecosystem.
