资源简介

A

◆ Welwitschia mirabilis

Title: the world’s most resistant plant

It’s not pretty to look at, but welwitschia mirabilis is unique. It consists of only two leaves and a strong stem with roots. Two leaves continue to grow and the stem thickens and can grow to be almost 2 meters high and 8 meters wide. Its lifespan is 400 to 1,500 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.

◆ Dionaea muscipula

Title: the Venus Fly Trap

Dionaea muscipula is the most famous carnivorous(肉食性的) plant due to the active and efficient nature of its unique trap. It may be famous, but it’s also threatened. It produces a short leaf that forms two sides of a trap. Each side contains some sensitive hairs. When it is touched two to three times, the trap will shut in less than a second, fast enough to catch flies and other insects. The leaf, once closed, produces some enzymes() that slowly dissolve the insects and supply the plant with food.

◆ Rafflesia arnoldii

Title: the world’s largest flower

Rafflesia arnoldii, the largest flower in the world, is an exotic and rare plant. The flower is 3 feet across and weighs 15-24 pounds. However, you wouldn’t want to grow it in your garden. In a rainforest-type environment, it gives off a most unpleasant smell, which is somewhat like rotten meat. This is why it is often called the Corpse Plant by some natives of Indonesia where it comes. Its flowers only last for three days to a week.

◆ Euphorbia obese

Title: the Baseball Plant

Euphorbia obese is known as the Baseball Plant. Over-harvesting by plant collectors for its interesting and curious appearance has severely reduced the wild population. However, it has become very common now. By growing euphorbia obese in large numbers, many gardens have been working to ensure that the plants being traded and sold among plant collectors are not wild plants.
