* The Guinness World Record for the heaviest pumpkin was set in 2016 by Mathias Willemijns from Belgium. Authenticated in Germany, his pumpkin weighed in at 1,190.49kg or 2,624.6lbs.
* Hawthorn flowers have a strong, complex scent, but the most distinct element is triethylamine. This is also one of the first chemicals produced by a dead human body when it starts to decay.
* Snowdrops contain a natural anti-freeze. Even if they collapse in freezing weather they recover once the temperature rises.
* Two thousand roses are needed to extract one gram of rose oil.
* Sunflowers display a behaviour called heliotropism. The young flowers face east in the morning and follow the sun as the earth rotates during the day. However, as the seeds develop and the flowers get heavier, the stems stiffen so that the mature flower heads tend to facing east.
* In 1982 Rockcress (Arabidopsis) was the first plant to flower and produce seeds in space (on the Soviet Salyut 7 space station).
* Lettuce, especially Romaine lettuce, contain a phytonutrient called lactucarium that helps promote sleep by sedating the nervous system.
* Jerusalem artichokes contain a sweet tasting soluble fibre called Inulin which passes through the human digestive system intact until bacteria go to work on it in colon, releasing a lot of gas in the process.
* It is possible to ‘taste’ Garlic with your feet. Experiments have shown that if a clove of garlic is rubbed on the underside of your feet, then sealed in plastic bags to isolate the smell, after about an hour has elapsed you will be able to taste garlic in your mouth. This is because the chemical Allicin in garlic can penetrate skin and travel around the body.
