Did you know?
The yellow iris is thought by some to be the original 'fleur-de-lis' - a common symbol of heraldry.
It is apotropaic, i.e. believed to avert evil. Thus it was hung in bunches outside the doors on the Feast of Corpus Christi in Ireland.
Medicinally used for its astringency, to stop blood flow. Also the roasted seeds have been used to make an coffee-like drink.
