Welwitschia mirabilis:World's Most Resistant
Plant
It's not
pretty to look at, but Namibia's
plant Welwitschia Mirabilis can truly claim to be one of a
kind. There really is nothing like it. Welwitschia plant consists of only two
leaves and a sturdy stem with roots. That's all! Two leaves continue to grow
until they resemble the shaggy mane of some sci-fi alien. The stem thickens,
rather than gains in height, and can grow to be almost 2 meters high and 8
meters wide. Their estimated lifespan is 400 to 1500 years. It can survive up to
five years with no
rain. The plant
is said to be very tasty either raw or baked in hot ashes, and this is how it
got its other name, Onyanga, which means onion of the desert.

Dionaea muscipula: the Venus Fly
Trap
The Venus Fly
Trap is the most famous of all carnivorous plants due to the active and
efficient nature of its unique traps. It may be famous, but it's also
threatened. The plant's two hinged leaves are covered in ultra sensitive fine
hairs that detect the presence of everything from ants to arachnids. Trigger the
hairs and snap! The trap will shut in less than a second.

Rafflesia arnoldii: World's Largest
Flower
There is one
exotic and rare plant you wouldn't likely want to grow anywhere near your
landscape no matter how famous it would
make you for doing so. That would be growing the largest flower in the world.
This exotic, very rare, speckled, though not particularly pretty, rust colored
flower is called Rafflesia Arnoldii.
Rafflesia Arnoldii, recently
assigned to the Euphorbiaceae family, is the biggest individually produced
flower in the world. It gets to be 3 feet across and weighing a whopping 15- 24
pounds. That's pretty darn big but still you would not like this flower in your
perennial bed. Why is that? If you could mimic a rainforest type environment for
this plant, it gives off a most offensive odor when in bloom. This scent is
somewhat like rotting meat. This is why it is often called the Corpse Plant by
some natives of Indonesia where it originates.
Its blossoms only last
three days to a week. But in those few days it needs a miracle or two just for
survival. This hideous smell it produces attracts pollinating insects to it to
help perpetuate the species. But even when this happens only 10-20 percent of
the tiny seedlings make it. With any luck in nine
months it blooms.

Desmodium gyrans: the Dancing
Plant
Darwin
called the plant Hedysarum; modern botanists call it either Desmodium Gyrans, or
more correctly these days, Codariocalyx Motorius. Its common name is Dancing
Grass or Telegraph Plant or Semaphore Plant -- after the leaf movements, which
resemble semaphore signals. For all of its uses this plant is easy to grow,
dancing happily on a sunny windowsill and watered when dry. Some say it dances
best to the "Greatful Dead!"

Euphorbia obesa: the Baseball
Plant
Euphorbia
Obesa, also known as the
Baseball Plant, is endemic to the Great Karoo region of
South Africa. Unsustainable harvesting by plant
collectors who value Euphorbia obesa for its interesting and curious appearance
has severely impacted wild populations. Consequently, national and international
legislation have been enacted to protect remaining populations. While Euphorbia
obesa remains endangered in its native habitat, it has become very common in
cultivation. By growing large numbers of Euphorbia obesa, nurseries and
botanical gardens have been working to ensure that specimens being
traded and sold among plant collectors
are not obtained from the wild.

Amorphophallus titanum: the Corpse
Flower
A flower
taller than a man, stinking strongly of putrefying roadkill and colored deep
burgundy to mimic rotting flesh, sounds like something from a low-budget science
fiction movie. But Indonesia's titan arum—or "corpse flower," as known by
locals—is a real, if rare, phenomenon, pollinated in the wild by carrion-seeking
insects. This
Indonesian plant,
called titan arum or amorphophallus titanium, has the world's biggest
inflorescence. Due to its fragrance, which is reminiscent of the smell of a
decomposing mammal, the Titan Arum is also known as a carrion flower, the
"Corpse flower", or "Corpse plant".

Baobab: the Bottle Tree
Baobab is the
common name of a genus (Adansonia) containing eight species of trees, native to
Madagascar, mainland Africa and Australia. Also known as the Bottle Tree, not
only do they look like bottles, but the trees typically store around 300 liters
of water! No wonder why they often live over 500 years!

Dracaena cinnabari: the Dragon Blood
Tree
Dracaena
Cinnabari is a Dragon Tree native to the Socotra archipelago. It is also
referred to as the Dragon Blood Tree and Socotra Dragon Tree. It is one of the
most striking of Socotra's plants, a strange-looking, umbrella-shaped tree. It
was first formally described by Isaac Bayley Balfour in 1882. A miniature Icon
of this tree is in
Windows as
Network-Icon. Its red sap was the dragon's blood of the ancients, sought after
as a medicine and a dye.

Mimosa púdica: the Shy Plant
Mimosa Pudica
(pudica = shy), or the Sensitive Plant, has a curiosity value: the compound
leaves fold inward and droop when touched or shaken, re-opening within minutes.
The species is native to South America and Central America, but is now a
pantropical weed. Who would know that plants have feelings too?

Selaginella lepidophylla: the
Resurrection Plant
Also
known as Rose of Jericho, the Selaginella Lepidophylla is a species of desert
plant noted for its ability to survive almost complete desiccation; during dry
weather in its native habitat, its stems curl into a tight ball and uncurl when
exposed to moisture. It is native to the Chihuahuan Desert.
