Exotic Flowers: By definition, exotic plants are plants that have been introduced to a region or ecosystem where they are foreign or non-native.
More often than not, these species of plants become invasive ones and dominate over the place. This tendency is thought to cause imminent damage to their neighboring plants and animals, and the environment as well.
Did you know that a lot of known cultivated ornamental flowering plants are exotic ones?

- This plant, which is endemic to Brazil, Paraguay, and Argentina, was introduced to Florida in the mid 1800s to be used as an ornamental plant. However, due to its ability to grow quickly, this plantcan easily dominate an area.
- It can compete with other nearby plants and obtain light, soil minerals, and moisture. It also can release chemical that can stop the growth of other plants, hence, the native plants are unable to survive.
- Its flowers, which bloom in September and October, are white in color and become important sources of nectar for insects like bees.
2. Melaleuca (Melaleuca Quinquenervia)
Known to be an aggressive invader , the Melaleuca is a flowering plant that can grow in almost any kind of habitat. Amazingly, it can turn any of these habitats into a dense forest that nothing else can live in.
- Originally, this plant was imported from Australia in the early 1900s in order to help in the drying of the Everdes. This is because of the Melaleuca’s ability to easily dry up an area by using up to five times more water uptake than the sawgrass.
- This plant, also known as the “Paper-bark“, is characterized by having barks that can be peeled into very thin sheets.
3. Latherleaf (Colubrina Asiatica)
Characterized by thick and massive vines, the Latherleaf Colubrina asiatica can easily grow quickly in coastal hardwood forests. It has greenish exotic flowers that occur in alternate infloresence.
- This plant can destroy any habitat for plant and animal life by interfering with water and nutrient cycles. As a vine, it can also grow massively and destroy any ground plants by blocking the light source from the sun.
- In the 1850s, this Asian plant was introduced to Jamaica and then gradually dominated Florida thereafter.
4. Australian Pine (Casuarina Equisetifolia)
Also known as the “Iron Wood” , the Australian pine is a type of tree that was imported from Australia for its timber and shade. However, due to the ability of this trees to flower all-year round, they can spread quickly and easily dominate an area.
- This tree can also easily grow thick foliage, which makes the plants down below it become devoid of sunlight. Its exotic flowers are characterized by apetalous flowers arranged in catkin inflorescence.
- During storms, they also facilitate erosion, making it hard for sea turtles to nest.
5. Dutch Amaryllis (Hippeastrum Reginae)
The Dutch Amaryllys is an indoor exotic flowering plant native to some regions in southern Africa and the United States.

- This plant can grow massively and easily crowd out other plants, resulting to the inhibition of the growth of its neighboring plants.
- This plant, also referred to as the Portia tree , is believed to have originated from India.
7. Anthurium (Anthurium Sp.)
The Anthurium is an exotic flowering species native to countries like Mexico and Argentina. It is characterized by its very distinct spadix flower with very bright red spathe.

10. Fiddleneck (Amsinckia Lycopsoides)
Indigenous to California, fiddlenecks are annual broadleaf plants that thrive in a wide range of habitats from grasslands, vineyards, and even disturbed places like roadsides.
- When ingested, fiddlenecks can be toxic to livestock. Sometimes, fiddlenecks can be problematic to crop fields as they can easily outgrow the cop themselves.
- Fiddlenecks are characterized by having very distinguishable flower heads that are curled like fiddlenecks (hence the name) and yellow funnel-like exotic flowers.
11. Bindweed (Convolvulus Arvensis)
Often referred to as “wild Morning Glory“, the bindweed Convolvulus truly looks like one. Basically, it is a climbing vine that wraps itself around poles or any other objects.
- The bindweed is easily distinguishable due to its pink trumpet-shaped exotic flowers and arrowhead-shaped leaves.
- The bindweed is very problematic due to a lot of reasons. The growth of a bindweed is very hard to control as it has a very large root system. Another reason is that it can produce seeds that can remain viable for many years.
12. Horseweed (Erigeron Canadensis)
Also called as the “Mares tail“, the horseweed is a summer annual plant characterized foliage growing as rosette around a crown. This plant is widely distributed among various habitats as it can live on agricultural lands, and even disturbed areas.
- This plant can grow rapidly and is a strong competitor for water. It is also characterized by having daisy-like flower heads.
- This plant is indigenous to North America and has since then become widespread to Asia and Europe.

- Contrary to the common belief of being a mere vegetable, this plant has bell-shaped exotic flowers that range from yellow to light greenish dioecious flowers.
- In Australia , the invasion of asparagus has already resulted to the decline of the number of native plant species. Hence, several modes for biocontrol has already been targeted.
- The word “asparagus” literally means “sprout” or “shoot” in Greek. This is f course related to the fact that asparagus is an edible shoot that grow on rhizomes in the soil.
18. Spotted Knapweed (Centaurea Maculosa)
The Spotted knapweed is a flowering plant native to Europe and Asia and since then has become very destructive to farmlands of the western United States.
- This plant is shown to have pink to purple flowers that are surrounded by green bracts with black tips.
- This Spotted knapweed is a very competitive plant as its tap root can suck water up faster than its neighboring plants. In addition to that, it releases a toxin from its roots that can somehow slow down the growth of nearby plants.
19. Bull Thistle (Cirsium Vulgare)
The Bull thistle Cirsium vulgare is a biennial flowering plant indigenous to Asia and Europe but was imported to North America. This plant, commonly found in vacant lots, and roadsides, is sometimes problematic due to its wide infestations.

- This plant originated from Europe and Asia and was established in North America in the 1760s.
22. St. John’s Wort (Hypericum Perforatum)
The St. John’s wort Hypericum perforatum is a flowering plant indigenous to Europe and Asia but has already been naturalized to temperate regions as an invasive species.
- The name “St. John’s wort” is derived from its blooming and harvesting season which often occurs on St. John’s Day (June 24).
- The exotic flowers of this plant come in cyme inflorescence at the upper end of branches and blossom in the late spring early summer.
- In medicine, the St. John’s wort is very popular for treating depression.

- This flowering plant has very distinctive finely divided leaves and numerous flowers located on each flowering stems.
- The Scentless Chamomile is a very aggressive plant can can grow rapidly once it has been established on soils.
24. Timothy (Phleum Pratense)
