Mother of thousands (Kalanchoe daigremontiana) is restricted or illegal in several regions (such as certain parts of Australia and parts of the southern United States) for three primary reasons:
Every single part of Mother of Thousands is toxic, even the tiny pups the leaves produce. If you grow this plant, make sure it's in a place that is out of reach of pets and children.
These virtually indestructible plants thrive on neglect and can survive missed waterings, low lighting, and temperature fluctuations. They are perfect for beginners or busy households.
Kudzu (Pueraria montana) is widely considered the most invasive plant in the US. Nicknamed "the vine that ate the South," it was introduced in 1876 and now covers over 3 million acres across the American Southeast. It grows up to a foot a day, aggressively smothering trees, buildings, and native ecosystems.
Morning glories are generally legal to grow and purchase in most U.S. states, but regulations vary heavily depending on the specific state and variety. While common garden varieties are widely available, a few specific species and uses are restricted.
Plant species containing DMT in their leaves, seeds, or bark include:
Pampas grass (Cortaderia selloana) is illegal to sell, propagate, or plant in several regions—including states like California, Hawaii, and Washington—primarily because it is an aggressive, invasive species that outcompetes native vegetation and degrades local ecosystems.
Several plants in nature contain potent toxins that can lead to muscle weakness or paralysis if ingested or, in some cases, touched. Identifying these plants is crucial for safety and preventing accidental poisoning:
The Tree of Heaven is scientifically named Ailanthus altissima. Its common name translates literally from the scientific name "Ailanthus" (derived from an Amboinese word meaning "tree of heaven" or "reaching for the sky") and its height. It is also known as stinking sumac or stink tree.
Do you know that this beautiful flowering plant is actually a silent killer? In 1807, the British brought it to India only for decoration. But this Lantana camara, which came out of the Kolkata Botanical Garden, has become an enemy of our forests today.
Research has shown that English Ivy can eliminate up to 78% of airborne mold within 12 hours. This makes it particularly useful in humid areas like bathrooms and basements where mold growth is more common.
The name “century plant” comes from the fact that the slow-growing plant takes years — although not 100 — to flower. The century plant, Agave Americana, is monocarpic, meaning it will bloom once in its lifetime. That bloom may not appear for 10, 20 or more years.
1. Snake Plant (Sansevieria): The Ultimate Survivor. If there were an award for the most indestructible plant, the Snake Plant would win. Known for its stiff, sword-like leaves, it is famous for its ability to thrive in almost any lighting condition.
The classic plant that universally says "I love you" is the Red Rose. However, if you are looking for long-lasting houseplants or specific symbolic meanings in the Victorian language of flowers, there are several wonderful alternatives to express your deepest affections.
That's why Feng Shui and interior design experts say it's a mistake to choose one of these five houseplants you should never place in your bedroom:
Yes, Mother of Thousands (Kalanchoe daigremontiana) grows exceptionally well indoors. In fact, keeping it as a houseplant is highly recommended to control its rapid spread, as it can become aggressively invasive if planted outdoors in warm, humid climates.
Pando, a clonal colony of quaking aspens in Utah, is estimated to be up to 80,000 years old. Rather than a single independent trunk, it is a massive network of over 40,000 genetically identical trees connected by one massive underground root system.
Certain trees are unsuitable for residential yards due to invasive roots that damage pipes and foundations, weak or brittle wood that snaps in high winds, and excessive debris that attracts pests. Planting these trees too close to your house often leads to expensive property damage.
A 9,000-year-old tree is typically a clonal tree, where a single ancient root system continuously sprouts new trunks over millennia.
Several plant species are known to contain potent toxins that can severely affect the central nervous system, leading to neurological symptoms such as confusion, disorientation, and amnesia. These plants are often highly poisonous and can be life-threatening if touched or ingested.
The answer depends on whether the metric is total deaths or potency per dose.
The Toothache Plant (Acmella oleracea), also known as the electric daisy or buzz buttons, is a well-known natural numbing plant. Its leaves and flowers contain a natural compound called spilanthol. When chewed, it creates an intense, temporary tingling and numbing sensation, making it a common folk remedy for oral pain.
Kudzu (Pueraria montana) is widely considered the most invasive plant in the US. Nicknamed "the vine that ate the South," it was introduced in 1876 and now covers over 3 million acres across the American Southeast. It grows up to a foot a day, aggressively smothering trees, buildings, and native ecosystems.
Though lush, ornamental grasses — especially pampas grass, ivy, and similarly overgrown groundcover — look great, they are some of the most reliable snake magnets in residential yards.
In late autumn or at the beginning of winter, the leaves of the pampas grass dry up. But they do not fall off by themselves, and in any case should not be cut off in autumn. It is better to tie the shoots together in the upper area before the first frost.
