A corpse flower grows in Brooklyn

Hold your nose! Our favorite rare and giant plant, the corpse flower or Amorphophallus titanum, could burst forth and stink up the air as early as today at the Brooklyn Botanic Garden. A botanist once likened its fragrance to "a cross between ammonia fumes and hydrogen sulphide, suggestive of spoiled meat or rotting fish."

The flower was first discovered in Sumatra, its native terrain, in 1878 by Odoardo Beccari. It was an immediate sensation. An English artist assigned to illustrate the plant is said to have become ill from the odor, and governesses forbade young women from gazing upon its indelicate form. (Its formal name ends in "phallus" for good reason.)

You can watch an almost-live webcam of the plant threatening to flower here. (Thank goodness Smell-O-Vision didn't work out.) After the jump, an introduction to our other favorite bizarre plant, from our fact library.

Venus Fly Trap The Venus flytrap plant seems like it should be native to the rain forest or some other exotic location — but that's not the case. In fact, they are only found on the coastal plains of North and South Carolina.

Popular misconceptions about the Venus flytrap abound. Here are just a few:

* The plant can actively attack.

* The "trap" is a mouth that the plant uses to eat.

* The plant can keep a home clear of flies.

Here's the truth:

* Venus flytraps only capture prey small enough for them to catch, and certainly do not have the strength to harm any creature larger than a small insect. The traps only spring shut when tiny hairs on their insides are triggered; they do not freely move to "seek" prey.

* The "trap" part of the plant is in fact one of its leaves. Although it does distribute digestive juices to absorb nutrients from the prey it captures, it has no true mouth. After the trap has "sprung" four or five times, it wilts away and is soon replaced by a new leaf-trap.

* After being triggered falsely, it usually takes a full day for a trap to re-open. It can take a trap several days to digest an insect, which means that it's unlikely that it can do enough pest control in the average home to make a noticeable dent.

In the wild, the plant has become rare and anyone caught removing these plants from their natural habitat can be subject to heavy fines. Any Venus flytrap plants offered for sale should be grown privately in greenhouses or nurseries.

Why Tiny 'Hedgehog Highways' Are Popping Up Around London

Hedgehogs as pets have gained popularity in recent years, but in many parts of the world, they're still wild animals. That includes London, where close to a million of the creatures roam streets, parks, and gardens, seeking out wood and vegetation to take refuge in. Now, Atlas Obscura reports that animal activists are transforming the city into a more hospitable environment for hedgehogs.

Barnes Hedgehogs, a group founded by Michel Birkenwald in the London neighborhood of Barnes four years ago, is responsible for drilling tiny "hedgehog highways" through walls around London. The passages are just wide enough for the animals to climb through, making it easier for them to travel from one green space to the next.

London's wild hedgehog population has seen a sharp decline in recent decades. Though it's hard to pin down accurate numbers for the elusive animals, surveys have shown that the British population has dwindled by tens of millions since the 1950s. This is due to factors like human development and habitat destruction by farmers who aren't fond of the unattractive shrubs, hedges, and dead wood that hedgehogs use as their homes.

When such environments are left to grow, they can still be hard for hedgehogs to access. Carving hedgehog highways through the stone partitions and wooden fences bordering parks and gardens is one way Barnes Hedgehogs is making life in the big city a little easier for its most prickly residents.

Big Questions
Where Should You Place the Apostrophe in President's Day?

Happy Presidents’ Day! Or is it President’s Day? Or Presidents Day? What you call the national holiday depends on where you are, who you’re honoring, and how you think we’re celebrating.

Saying "President’s Day" infers that the day belongs to a singular president, such as George Washington or Abraham Lincoln, whose birthdays are the basis for the holiday. On the other hand, referring to it as "Presidents’ Day" means that the day belongs to all of the presidents—that it’s their day collectively. Finally, calling the day "Presidents Day"—plural with no apostrophe—would indicate that we’re honoring all POTUSes past and present (yes, even Andrew Johnson), but that no one president actually owns the day.

You would think that in the nearly 140 years since "Washington’s Birthday" was declared a holiday in 1879, someone would have officially declared a way to spell the day. But in fact, even the White House itself hasn’t chosen a single variation for its style guide. They spelled it “President’s Day” here and “Presidents’ Day” here.

Maybe that indecision comes from the fact that Presidents Day isn’t even a federal holiday. The federal holiday is technically still called “Washington’s Birthday,” and states can choose to call it whatever they want. Some states, like Iowa, don’t officially acknowledge the day at all. And the location of the punctuation mark is a moot point when individual states choose to call it something else entirely, like “George Washington’s Birthday and Daisy Gatson Bates Day” in Arkansas, or “Birthdays of George Washington/Thomas Jefferson” in Alabama. (Alabama loves to split birthday celebrations, by the way; the third Monday in January celebrates both Martin Luther King, Jr., and Robert E. Lee.)

You can look to official grammar sources to declare the right way, but even they don’t agree. The AP Stylebook prefers “Presidents Day,” while Chicago Style uses “Presidents’ Day.”

The bottom line: There’s no rhyme or reason to any of it. Go with what feels right. And even then, if you’re in one of those states that has chosen to spell it “President’s Day”—Washington, for example—and you use one of the grammar book stylings instead, you’re still technically wrong.
