Sphagneticola trilobata, commonly known as the Bay Biscayne creeping-oxeye, [3] merigold Singapore daisy, creeping-oxeye, trailing daisy, and wedelia, [4] [5] is a plant in the tribe Heliantheae of the family Asteraceae. It is native to Mexico, Central America, and the Caribbean, but now grows throughout the Neotropics. It is widely cultivated as an ornamental groundcover. [6]
Spreading, mat-forming perennial herb up to 30 cm in height. Has rounded stems up to 40 cm long, rooting at nodes and with the flowering stems ascending. Leaves are fleshy, hairy, 4–9 cm long and 2–5 cm wide, serrate or irregularly toothed, normally with pairs of lateral lobes, and dark green above and lighter green below. Its surface is hairy or glabrous, rarely scaly.
Peduncles are 3–10 cm long; involucres are campanulate to hemispherical, about 1 cm high; chaffy bracts are lanceolate, rigid. The flowers are bright yellow ray florets of about 8-13 per head, rays are 6–15 mm long; disk-corollas 4–5 mm long. The pappus is a crown of short fimbriate scales. The seeds are tuberculate achenes, 4–5 mm long. Propagation is mostly vegetatively as seeds are usually not fertile. [4] In the tropics it is free-flowering, [7] and elsewhere it blooms mostly from spring to autumn. [8]
It has a very wide ecological tolerance range, but grows best in sunny areas with well-drained, moist soil at low elevations. [6] [9]
Sphagneticola trilobata is listed in the IUCN's “List of the world's 100 worst invasive species”. [10] It is spread by people as an ornamental or groundcover that is planted in gardens, where it can escape to surrounding areas by dumping of garden waste. It spreads vegetatively, not by seed. It rapidly forms a dense ground cover, crowding away and preventing other plant species from regenerating. This species is widely available as an ornamental and is therefore likely to spread further.
It is a noxious weed in agricultural land, along roadsides urban waste places and other disturbed sites. It is also invasive along streams, canals, along the borders of mangrove swamps and in coastal vegetation.
It is widespread as an invasive species on the Pacific Islands, Hong Kong, South Africa, Australia, Indonesia, and Sri Lanka. [4] [6] [11] [9]
Groundcover or ground cover is any plant that grows low over an area of ground, which protects the topsoil from erosion and drought. In a terrestrial ecosystem, the ground cover forms the layer of vegetation below the shrub layer known as the herbaceous layer, and provides habitats and concealments for terrestrial fauna. The most widespread ground covers are grasses of various types.
Leucanthemum vulgare, commonly known as the ox-eye daisy, oxeye daisy, dog daisy, marguerite and other common names, is a widespread flowering plant native to Europe and the temperate regions of Asia, and an introduced plant to North America, Australia and New Zealand.
Viola pedunculata, the California golden violet, Johnny jump up, or yellow pansy, is a perennial yellow wildflower of the coast and coastal ranges in California and northwestern Baja California. The common name "Johnny jump up" is usually associated with Viola tricolor however, the introduced garden annual.
Bellis perennis, the daisy, is a European species of the family Asteraceae, often considered the archetypal species of the name daisy. To distinguish this species from other plants known as daisies, it is sometimes qualified or known as common daisy, lawn daisy or English daisy.

It has a wide distribution in coastal areas of South Africa, extending from Namaqualand to Cape Point and as far as KwaZulu-Natal.
Ipomoea cairica is a vining, herbaceous, perennial plant with palmate leaves and large, showy white to lavender flowers. A species of morning glory, it has many common names, including mile-a-minute vine, Messina creeper, Cairo morning glory, coast morning glory and railroad creeper. The species name cairica translates to "from Cairo", the city where this species was first collected.
Vinca major, with the common names bigleaf periwinkle, large periwinkle, greater periwinkle and blue periwinkle, is a species of flowering plant in the family Apocynaceae, native to the western Mediterranean. Growing to 25 cm (10 in) tall and spreading indefinitely, it is an evergreen perennial, frequently used in cultivation as groundcover.
Rudbeckia triloba, the browneyed or brown-eyed susan, thin-leaved coneflower or three-leaved coneflower, is a species of flowering plant in the family Asteraceae with numerous, yellow, daisy-like flowers. It is native to the central and eastern United States and is often seen in old fields or along roads. It is also cultivated as an ornamental.
Saxifraga stolonifera is a perennial flowering plant known by several common names, including creeping saxifrage, strawberry saxifrage, creeping rockfoil, Aaron's beard, mother of thousands, roving sailor, and strawberry begonia or strawberry geranium, though it is neither a true begonia nor a geranium; both these latter plants belong to different families.
Pachysandra terminalis, the Japanese pachysandra, carpet box or Japanese spurge, is a species of flowering plant in the boxwood family Buxaceae, native to Japan, Korea and China and introduced to eastern North America. It is a slow-growing, spreading evergreen perennial growing to 10 cm (4 in) tall by 60 cm (24 in) broad, with alternate, simple, glossy leaves, and creeping stems. The leaves may yellow in direct sunlight or in winter. When growing in a spreading mass of many plants, a dense cover is formed.
Senecio angulatus, also known as creeping groundsel and Cape ivy, is a succulent flowering plant in the family Asteraceae that is native to South Africa. Cape ivy is a scrambling herb that can become an aggressive weed once established, making it an invasive species. It is grown as an ornamental plant for its satiny foliage and sweet-scented flowers.
Liriope muscari is a species of flowering plant from East Asia. Common names in English include big blue lilyturf, lilyturf, border grass, and monkey grass. This small herbaceous perennial has grass-like evergreen foliage and lilac-purple flowers which produce single-seeded berries on a spike in the fall.

Tamarix chinensis is a species of tamarisk known by the common names five-stamen tamarisk and Chinese tamarisk or saltcedar. It is native to China and Korea, and it is known in many other parts of the world as an introduced species and sometimes an invasive noxious weed. It easily inhabits moist habitat with saline soils. It may grow as a tree with a single trunk or as a shrub with several spreading erect branches reaching 6 metres or more in maximum height. It has been known to reach 12 metres. It has reddish, brown, or black bark. The small, multibranched twigs are covered in small lance-shaped, scale-like leaves which are no more than about 3 mm long. The inflorescence is a dense raceme of flowers a few cm long. Each fragrant flower has five petals which are usually pink but range from white to red.

The infertile form is often cultivated as a ground cover, while the fertile form spreads rapidly in disturbed areas like beside roads and trails, threatening native ecosystems. It is listed as an invasive weed in California and Australia.
Rubus tricolor is an evergreen prostrate shrub, native to southwestern China. Leaves are dark green above, pale green below, and stems have red bristles.
