Popular both as garden plants and cut flowers, the flowers are described using terms such as falls, standards and beard.
- The standards are the three upper petals, they rise upwards.
- The falls are the three that drop down.
- The beard is the distinguishing feature that sits on the fall. A fuzzy strip that give the plant its name. You can see the beard on the yellow flower pictured right.
So a flower may be described as yellow standards and yellow falls, or maybe having light blue standards and deep blue falls.
