What's the fastest growing plant or herb in our planet and how fast?

Answer 1

It does seem to be the bamboo in terms of strictly plants. This kelp here grows pretty fast. Let me quote this link from Wayne's Word:

"The record for the fastest growth of an individual goes to a tropical species of bamboo that reportedly reaches 100 feet (30 m) in three months. [Note: This is an unsubstantiated report. It might be only 50 feet (15 m) in three months.] Growth increments of three feet (0.9 m) a day have been recorded--an astonishing 0.0002 miles per hour. The record for total growth in length after a period of time may go to a species of marine algae. The Pacific giant kelp (Macrocystis pyrifera) may grow up to 150 feet (46 m) or more in length, and has been clocked at 18 inches a day. It has also been estimated that if all the filamentous hyphae produced in one day by a single massive soil fungus permeating acres of forest soil were laid end to end, they could extend for nearly a mile."

Okay, so it appears that there is a type of fungus that grows pretty darn fast too, based on that. You might want to ask what fungus grows the fastest and how fast does it grow too. This website has all sorts of interesting plant trivia items such as largest tree, oldest tree, largest fruits, and so on.

Answer 2

Kelp Are the fastest growing plants.
"Kelp are large seaweeds (algae), belonging to the brown algae and classified in the order Laminariales. Despite their appearance they are not grouped with the normal aquatic or land plants (kingdom Plantae), but instead are included in either kingdom Protista or Chromista. There are about 30 different genera. Kelp grows in underwater forests (kelp forests) in clear, shallow oceans, requiring nutrient-rich water below about 20 °C. It offers protection to some sea creatures, or food for others. It is known for its high growth rate — the genus Macrocystis and Nereocystis luetkeana grow as fast as half a metre a day, ultimately reaching 30 to 80 m.[1]"

Answer 3

Some forms of bamboo are the fastest growing plant, and can increase by up to a foot a day, when shoots are growing.

Answer 4

Once established, kudzu plants grow rapidly, extending as much as 60 ft per season at a rate of about 12 in per day. This vigorous vine may extend 30–100 ft in length, with basal stems 1–4 inches in diameter. Kudzu roots are fleshy, with massive tap roots 4–8 in or more in diameter, reaching depths of up to 12 feet in older patches, and weighing as much as 180 kg. As many as thirty stems may grow from a single root crown.

Answer 5

Curly Parsley grows very immediately and it makes a extreme-high quality furry little plant. start quickly, because of the fact plant life take time to germinate and improve. Radish seeds sown thickly staggering of the dirt in a small field will improve right into a sprouts in below 2 weeks.

Answer 6

The very fastest is kelp, a sea weed...easily a foot per day

Answer 7

probably bamboos are the fastes growing plants on earth
