Gladiolus Classification

The following is taken from our mail order catalogue (page 4) with some additional photos.
The British Gladiolus Society classify Gladioli to aid with showing and judging. However the information can also be useful for gardeners when selecting corms for size and colour.

Each exhibition gladiolus that we have listed includes information such as: 454 M (Bloggs 99) 8;23;30

The three digit number:-  454  refers to the size, colour and shade, (4: size, 5: colour, and 4: shade)

If the first digit is:sizes-of-glads

5  this equals 500 size (giant flowered: 5.5 inches or more across the bottom floret)
4  this equals 400 size (large flowered: 4.5 inches or more across the bottom floret)
3  this equals 300 size -medium flowered: 3.5 inches or more across the bottom floret)
2  this equals 200 size (small flowered: 2.5 inches or more across the bottom floret)
1  this equals 100 size (miniature flowered: 1.5 inches or more across the bottom floret)

 

The second digit refers to the colour, the third to the shade, in our example 54 is medium red.
