Editing Triffid (section)

===Initial appearance and cultivation===
In the novel, it is stated that the first triffids appeared in equatorial regions. Though they develop faster in tropical zones, triffids soon established themselves worldwide, outside the [[Polar region|polar]] and [[desert]] regions. When it was discovered that triffids are venomous, they were almost exterminated, until they were identified as the source of valuable oil. Farms were then built to cultivate them.

Upon the discovery that [[Docking (animal)|docking]] their stingers renders them harmless, docked triffids became fashionable in public and private gardens. These triffids are safe provided they are pruned annually, as they take two years to fully regrow their stingers. Farmed triffids are not docked because undocked triffids produce higher quality oil.
