5 Deceptively Dangerous Herbaceous Plants l Our Breathing Planet

We truly hope that you enjoy this article about 5 Deceptively Dangerous Herbaceous Plants. Nature never ceases to amaze us with its variety and resourcefulness. This principle is perfectly demonstrated in the fact that many seemingly innocent, and sometimes lovely, plants can actually be quite dangerous. So sit back and enjoy learning about these 5 Deceptively Dangerous Herbaceous Plants.

Rosary Pea

Rosary Pea Facts

Heading up this listing of 5 Deceptively Dangerous Herbaceous Plants is one that may astonish many people, the Rosary Pea.
First of all, the term serves as the common name for an extremely remarkable variety of herbaceous flowering plant. Also known by the scientific name of the Abrus precatorious, this plant proves that beauty can conceal danger.
That’s due to the fact that the plant holds a dark secret. This innocent-seeming plant actually contains high quantities of a chemical compound called abrin. This chemical holds a very close relationship with the incredibly deadly chemical, risin.
In point of fact, the consumption of even a single berry can prove fatal to an average-sized human being. Quite incredibly, despite this fact, the colorful berries of this particular flora have long been used by man for many purposes.
Ironically, these ultra-deadly small fruits were long used for an astonishing purpose, given their toxicity. These formed the original source of the rosary beads used in worship. That, therefore, formed the basis of the common name for the deadly plant.
For the moment, the remarkable Rosary Pea appears to have a stable population. Further, this fortunate situation seems to hold true throughout the entirety of its native range. As a result, the IUCN currently has no listing for it.
Nevertheless, the lovely but dangerous plant likely faces several threats to its continued existence. Like many species today, these likely include the danger of habitat loss. But its greatest threat most likely consists of climate change.

Rosary Pea Physical Description

Firstly, botanists categorize the Rosary Pea as a legume. This occurs because this perennial plant develops in the form of a slender, climbing vine. In addition, the species frequently twists its way around trees, hedges, and shrubs.

Secondly, its leaves develop as quite slender, and roughly 5 in (12.7 cm) long. Further, the thin branches develop as herbaceous in nature. The flowers remain small and show either white, violet, or pink, and typically grow densely clustered.

Thirdly, the deadly seeds of the fascinating plant develop within small pods. These average roughly 2 in (5.1 cm) in length. Each pod contains 3-8 of the seeds, and thankfully, the shell of each produces a relatively thick and hard covering.

Finally, the seeds of the Rosary Pea themselves appear in different color varieties. However, the red color with a black spot remains the most common of the combinations. Nevertheless, white, green, and black seeds occur as well.

Kingdom: Plantae
Phylum: Angiosperm
Class: Eudicots
Order: Fabales
Family: Fabaceae
Genus: Abrus
Species: A. precatorius

Rosary Pea Distribution, Habitat, and Ecology

The remarkable Rosary Pea evolved as endemic to several continents. These include the regions of Asia, Africa, and Australia. However, this remarkably adaptable species has now been spread to most regions of the world with compatible climates.

These areas into which it has been artificially introduced include the Caribbean Islands, Belize, Hawaii. In addition, this also includes parts of that state of Florida, in the United States, in North America, as well as the country of India.

Although it did evolve as a highly adaptable species, the plant nevertheless has types of climate that it prefers. These primarily consist of regions of subtropical forests. Although it’s quite tolerant of most types of soil, it flourishes best where that soil is well-drained.

It most commonly spreads via the distribution of its numerous seeds. These seeds, created in vast numbers, remain viable for an entire year. Due to this aggressive nature, in these regions, people generally consider the Rosary Pea an invasive species.

That’s true because it has proven to be extremely adaptable, and difficult to eradicate in these areas. This occurs partly because its roots grow extremely deep and nearly impossible to remove. In fact, burning, intentional or otherwise, actually encourages it to grow.

Texas Bluebonnet

Texas Bluebonnet Facts

Our next entry in this compendium of 5 Deceptively Dangerous Herbaceous Plants is the seemingly delicate Texas Bluebonnet.
First of all, the highly distinctive name of the flora serves as one of the common names of a seemingly delicately beautiful plant. However, this wonderful marvel of Nature also goes by the alternate common name of the Texas lupine.
Furthermore, it also possesses the slightly complex scientific name of the Lupinus texensis. By either name, though, its remains a deceptively sturdy species. This fantastic plant also typically presents in only its base form.
However, in recent years, this has begun to change within its naturally occurring populations. That holds true due to the surprising fact that isolated mutations of the beautiful plant have recently begun to appear in scattered portions of its range.
For the moment, at least, botanists remain at a loss for an explanation for this. Regardless of this, though, the state of Texas officially recognizes both the original species of the flower, and all mutations of it, as the state flower.
Despite the limitations of its range, it appears to be maintaining a stable population base. Therefore, the IUCN currently lists it as Least Concern. But, it must be considered to be at some risk. Like many species, its greatest threat comes from climate change.

Texas Bluebonnet Physical Description

The truly stunning Texas Bluebonnet boasts several physiological characteristics that make it worthy of note. Firstly, the plant has quite humble beginnings. That holds true due to the fact that this gorgeous plant begins its life as an extremely tiny seed.

Secondly, that tiny source of life also has an extremely tough outer layer. It remains so tough that it often takes months, or even years for the weather to erode the outer layer. This means that germination quite often never has the chance to occur, depending on weather.

Once germinated, however, the tiny seedling of the species most commonly appears in the Fall. Furthermore, the stunning plant evolved as a biennial species. In addition, the plant grows slowly during the winter and does not attain full growth until the onset of Spring.

But, once the gorgeous flora does reach its full growth, the flower typically reaches a maximum height measuring around 24 in (60 cm). In addition to its size, the magnificent Texas Bluebonnet presents a striking visual image to those who encounter it.

In point of fact, the individual specimens boast some stunning colors. Individuals plants primarily develop as dark blue in color. But, although rare, variations in this basic pattern do occur. Further, the colors of these isolated mutations include pink, maroon, and white.

Kingdom: Plantae
Phylum: Angiosperms
Class: Eudicots
Order: Fabales
Family: Fabaceae
Genus: Lupinus
Species: L. texensis

Texas Bluebonnet Distribution, Habitat, and Ecology

Unfortunately for those who appreciate its beauty, the Texas Bluebonnet only inhabits a small section of the globe. It only lives in a small portion of the continent of North America. More specifically, though, it mainly appears in the state of Texas, in the United States.

Nevertheless, it also appears in smaller, widely scattered populations in the states of Florida, Oklahoma, and Louisiana. Furthermore, even within this highly restricted range of habitation, it shows decided preferences for the regions it inhabits.

In point of fact, and surprisingly, these generally constitute relatively inhospitable regions. The species most often prefers loose, often rocky soil. The truly beautiful flower also commonly grows in uncultivated areas, including prairies, and along roadsides.

In addition, the beautiful Texas Bluebonnet most typically grows in areas of direct sunlight. Here, its dazzling color scheme creates a visually dynamic effect to observe. However, its beauty, as is often the case in Nature, conceals a dangerous attribute.

That holds true due to the fact that this delicate wildflower also lists as moderately toxic. But, it does not generally pose a threat to humans unless ingested. Meanwhile, the Angiosperm also serves as an important food source for several butterflies.

Lotus Corniculatus

Lotus Corniculatus Facts

Placing third among our choices of 5 Deceptively Dangerous Herbaceous Plants, but only due to random selection, comes the Lotus Corniculatus.
That term serves as the scientific name of a stunning and extremely unusual small flowering plant. It also goes by several common names. These include the birdsfoot deervetch, and even the comical sounding eggs and bacon.
But, regardless of the name one uses for it, the gorgeous plant remains a true marvel of Nature. This actually holds true for reasons other than just its beauty. Believe it or not, the stunning species actually constitutes a member of the pea family.
However, you do not want to eat it, regardless of its remarkable visual appeal. That’s due to an astonishing fact. That’s the fact that this little beauty actually contains naturally occurring trace amounts of the deadly chemical cyanide.
In extremely small amounts, however, this beautiful and remarkable species does have some medicinal uses. To the great surprise of many people, though, the beautiful plant also actually gets widely used as a source of forage for livestock.
The majority of animal kept as livestock, fortunately for them, have an advantage over human beings. That’s true since many of these animals can eat the beautiful yet dangerous Lotus Corniculatus without incurring any harmful effects.
Most animals have a much greater natural tolerance for small concentrations of cyanide than homo sapiens. Fortunately, the lovely flora also has a comparatively wide range of distribution. Therefore, the IUCN has no listing for it.

Lotus Corniculatus Physical Description

Most notably, though seemingly extremely delicate, the magnificent Lotus Corniculatus surprises most people. That’s due to the fact that this particular variety of Angiosperm holds many surprises. Among those is the fact that it’s actually quite hardy.

Nonetheless, sheer physical size does not rank as one of the astounding characteristics of the beautiful Angiosperm. That remains true since this herbaceous plant only achieves a maximum known height of about 8 in (20 cm) unless supported by other plants.

Further, this stunning flora most commonly grows in a sprawling manner along the ground. But it rarely does so over great distances. In addition, the small flowers of the gorgeous Lotus Corniculatus display combinations of orange and yellow color.

Also, and not surprisingly, since it is part of the pea family, the seeds develop in small, elongated pods. Furthermore, the leaves of the plant most commonly grow in groups of five. Typically, three of these form a trefoil pattern over the other two.

Kingdom: Plantae
Phylum: Angiosperms
Class: Eudicots
Order: Fabales
Family: Fabaceae
Genus: Lotus
Species: L. corniculatus

Lotus Corniculatus Distribution, Habitat, and Ecology

First of all, the visually breathtaking, and scientifically fascinating, Lotus Corniculatus remains endemic to a remarkably large section of the globe. In point of fact, the plant inhabits a wide swathe of the continents of Europe, Asia, and Northern Africa.

Furthermore, within that truly impressive geographical range of habitation, the plant also predominantly appears in regions of grasslands. But, regardless of its habitat, this marvelous species of flora qualifies as far more than just another visually appealing creation of Nature.

This particular Angiosperm also has an incredibly extreme level of durability. This holds true even to the point of surviving being trampled by livestock. In addition, this unexpectedly tough species also grows equally well in both nutrient-rich soils and nutrient-poor soils.

Further, the Lotus Corniculatus most commonly grows in areas that most plants would find forbidding. In point of fact, this primarily consists of regions of grassland with a high percentage of sand. Few species with comparable beauty can make this claim.

Due to its hardiness, farmers often actually use it in cultivation, especially in certain parts of Europe. Finally, as a result of this practice, it has become considered an invasive species in some portions of Australia and North America.

Rosy Periwinkle

Rosary Pea Facts

Appearing next in this article about 5 Deceptively Dangerous Herbaceous Plants is the lovely Rosy Periwinkle.
Firstly, the plant has far more to offer than just beauty. It forms a beautiful plant with incredible botanical usefulness. This stunning species also holds the unfortunate distinction of presently being quite rare and endangered.
Secondly, its truly majestic beauty has another side effect. That holds true due to the fact that the plant also understandably became quite popular as an ornamental plant. Despite its delicate appearance, this plant remains an extremely hardy species.
The delicate marvel of Nature, quite unfortunately, also has an extremely limited endemic range. Within that range, however, the flora now faces the threat of loss of habitat due to the practice of slash and burn agriculture.
Fortunately, though, it proved to be highly adaptable and became naturalized in numerous other parts of the world. Nevertheless, within that limited home range, it now finds itself facing the very real potential threat of extinction in the wild.
That lamentable state holds true due to the fact that, like many other species, it now must deal with the ongoing effects of climate change. Despite this, the IUCN currently has no listing for the Rosy Periwinkle on its Red List of Threatened Species.

Rosy Periwinkle Physical Description

The beauty of the Rosy Periwinkle conceals a surprising character. That’s because the gorgeous variety of flora is also highly versatile in nature. This holds true due to the fact that the Angiosperm develops as either a herbaceous plant or an evergreen shrub.

It also grows either vertically or runs along the ground, allowing it to inhabit different areas. It also attains heights of as much as 3.1 ft (1 m). In addition, the flowers of this marvelous plant appear either white with a red center or a dark pink, making for a striking contrast.

Its leaves typically display a glossy green in color. These develop a thick leathery texture. The fruit of the Rosy Periwinkle develops as an elongated follicle. This feature also most often appears in pairs. The sap of this plant has the consistency of a thick, milky white latex.

Kingdom: Plantae
Phylum: Angiosperms
Class: Eudicots
Order: Gentianales
Family: Apocynaceae
Genus: Catharanthus
Species: C. roseus

Rosy Periwinkle Distribution, Habitat, and Ecology

The incredibly lovely Rosy Periwinkle evolved as native to not only a limited region of the world, but a isolated one, as well. This flowering plant actually grows only on the island of Madagascar. This fabulous site itself remains an extremely unique location.

The beauty of the plant also conceals another surprise. It represents a veritable cornucopia of useful chemical compounds. In fact, some of the chemicals in the Rosy Periwinkle also have high toxicity, and ingestion of even a small amount can be fatal.

However, many of the other chemical compounds within the flower prove invaluable in saving lives. Thus, it proves itself to be highly useful. Some of the diseases treated by its compounds include a variety of cancers, diabetes, Hodgkin’s lymphoma, and even malaria.

Giant Hogweed

Giant Hogweed Facts

The fifth and final entry into our compendium of 5 Deceptively Dangerous Herbaceous Plants is the incredible Giant Hogweed.
Perhaps most notably, the astonishing plant known as the Giant Hogweed hides a truly dark secret. The unassuming plant remain quite poisonous. In fact, the innocent looking species actually ranks as one of the most dangerous plants on earth.
This apparently bizarre fact occurs because of the nature of the naturally occurring sap of the remarkable plant. This ever-present liquid component of the flora evolved quite astonishingly powerful phototoxic properties.
Not only that, but it’s produced by the plant in extremely copious quantities. Therefore, once on the skin, this powerful natural chemical causes extraordinary amount of damage to human skin. It frequently creates extreme blisters.
These blisters can also generate severe scarring when exposed to light. Unfortunately, these terrible effects are not short-lived. To the horror of those exposed to it, in some individuals, these scars can last for months, or even years.
Finally, one more factor makes the Giant Hogweed potentially severely dangerous. Its danger becomes compounded by its strong resemblance to another, harmless plant. This is the Queen Ann’s Lace, a popular ornamental plant.

Giant Hogweed Physical Description

Firstly, the Giant Hogweed typically grows to an amazing height. This vertical growth typically measures between 6.5 ft and 16.5 ft (2 – 5 m), itself an impressive measurement. But, under ideal conditions, the plant has the ability to grow as tall as 18 ft (5.5 m).

Secondly, a grown plant also produces numerous, large leaves. Further, these sometimes have a width of as much as 5 ft (1.5 m). Also, these grow from a strong, thick stem. This develops colored bright green. The leaves also have dark blotches and rough white hairs.

The large, umbrella-shaped head of this surprising plant boasts another astonishing dimension. The head, or crown, can measure as much as 39 in (1 m) across. In addition, the usually relatively thick stems these grow from also contain the thick, highly dangerous sap.

The flowers of the Giant Hogweed generally develop as small. Nonetheless, they also appear in copious numbers. These small but numerous blooms usually show either white or greenish-white in color. The fruits produce large dry seeds that average 0.4 in (1 cm).

Kingdom: Plantae
Phylum: Angiosperms
Class: Eudicots
Order: Apiales
Family: Apiaceae
Genus: Heracleum
Species: H. mantegazzianum

Giant Hogweed Distribution, Habitat, and Ecology

First of all, the highly prolific Giant Hogweed evolved as native to the Caucasus Mountains, located in Russia. However, the startling species quickly spread to a remarkably wide swathe of western and northern sections of Europe.

Later, it also spread to the countries of Canada and the United States, in North America. There, it quite understandably remains considered an invasive species in many regions. It further displays a remarkable ability to adapt to varied habitats.

However, the remarkable variety of flora primarily thrives in certain, specific types of areas. Therefore, it’s concentrations appear greatest in such regions of the areas it inhabits as coastal areas, along river banks, and in temperate forests.

The plant requires several years of growth before it produces seeds. But, once the Giant Hogweed does, it commonly creates them in vast numbers. In fact, each individual plant typically produces in excess of 20,000 seeds, assuring its ability to spread rapidly.

It’s not just the effects of contact with its sap that serves as the source of what makes it dangerous. The danger is augmented by the speed of its effects. The symptoms typically appear within 15 minutes of contact with the skin and exposure to light. Then, a rash appears.

But this persistent and rapidly-spreading rash can also become quite severe, leaving acid-like burns on the skin. Just a minimum contact with the eyes can cause permanent blindness. Finally, extensive exposure, even just to the skin, can prove fatal in some instances.
