An upright growing, deciduous, bulbous, perennial iris, growing to approximately 50cm (20in) high and having a spread of 45cm (18in). After the bulb has produced its foliage, flowered and completed its growth cycle, the foliage yellows and dies back in early summer. It has pointed strap-shaped, light green leaves and in spring produces several flowers per stem, with three narrow standards in deep purple and three broad, bronze-purple falls with darker veination, each with a brilliant yellow eye. It can be used in spring bedding schemes and in wildflower areas where it can be left to naturalise

Horticultural Classification Codes

Horticultural Classification Codes are often given to genera which have a large number of species or cultivars. They are used to categorise cultivated plants based on specific, shared characteristics such as shape, colour, size or flowering time, and can be displayed as letters or numbers

For example:
Dahlia ‘Sunset Kate (Sin) = Single flower
Rosa ‘Marigold’ (HT) = Hybrid Tea: Dutch Iris are herbaceous bulbous perennials with narrow, channelled leaves and blue yellow or white flowers in late spring and early summer
