Giant sensitive plant

Mimos diplotricha

The giant sensitive plant is indigenous to Brazil in South America. It is a shrubby or sprawling annual that climbs over other vegetation, behaves as a perennial in favourable conditions and is known to invade pastures, cane fields and crops.


Giant sensitive tree

Mimosa pigra

Giant sensitive tree is a woody invasive shrub that originates from Brazil and has now become widespread throughout the tropics. It favours wet tropical climates. It has the potential to spread through natural grassland floodplain ecosystems and pastures, converting them into unproductive scrub land, which is only able to sustain lower levels of biodiversity. It is on the list of the world's 100 worst invasive species in the Invasive Species Specialist Groups Global Invasive Species Database. 


Golden wattle

Acacia pycnantha

Slender, evergreen tree 4-8m high with drooping branches and dull green, leathery, distinctly curved leaves. Bright yellow, spherical flowerheads in large sprays from August to September. Brown, almost straight pods.


Goosefoot

Syngonium podophyllum

 Goosefoot is an ornamental vine that has established invasive populations in South Africa, displacing indigenous plants and growing over indigenous trees. The plant has blue-green or green younger stems and leaf stalks. All parts of the plant are poisonous, causing severe mouth pain if eaten.


Granadilla - Passion fruit

Passiflora edulis

The granadilla or passion fruit is a vine species of passion flower that is native to Brazil, Paraguay and northern Argentina. It is a vigorous, climbing vine that clings by tendrils to almost any support. It can grow 15-20m per year once established. It is generally short-lived (5-7 years).


Granadina

Passiflora subpeltata (Passifloraceae)

A glabrous, climbing perennial with cylindrical stems reaching up to 5m high. It has shallowly three-lobed leaves with large stipules and pure white flowers 50mm across which appear during November-June. Produces globular green berries about 50mm long which turn yellowish. This tendril climber invades woodlands, bush clumps, roadsides and river banks.


Greater Periwinkle

Vinca Major

Perennial, evergreen herb with erect flowering stems to 450 mm high. This species prefers shaded habitats and is a weed of urban bushland, open woodlands, watercourses (i.e. riparian areas), roadsides, gardens, disturbed sites and waste areas in temperate and occasionally also sub-tropical regions. Leaves are green, sometimes with creamy margins, glossy, ovate, 25-60 mm wide. Flowers are blue- violet, sometimes white, 30- 50 mm wide with five spreading lobes, solitary in leaf axils


Green mother of milllions

Bryophyllum proliferum

Perennial, erect, hairless, succulent herb or long. Flowers box shaped, pendulous less than 30mm long, calyx is green, corolla is green or reddish. Adventitious plantlets are produced on the mature inflorescence hence the common name proliferum.


Green wattle

Acacia decurrens (Fabaceae)

A large evergreen tree 5-10m high with bright green feathery leaves origination from Australia. Bright yellow round flower heads in large, showy, fragrant sprays appear in July to August and produce dark brown seed pods. 


Guava

Psidium guajava (Myrtaceae)

Evergreen shrub or small tree up to 10m high with hairy branchlets. Bronze turning light green leaves that are hairy below and have conspicuous veins. White flowers in groups of 1-3 from October to December. Green turning yellow fruits with white, yellow or pink flesh and a musky odour
