Brown seems a popular choice of iris at the moment, if the enquiries on the nursery website are any guide.
Many of the 'brown' irises are more copper than chocolate: Dutch Chocolate is an example where the rich coppery-red flowers are a surprise if you are expecting a dark rich brown that the name implies.
Many others have brown markings on an overall blue or yellow colour scheme - Gallant Moment, for example. Others have brown elements, like Medway Valley which has brown standards and white/purple falls.
Here are two mostly brown tall bearded irises. Firstly, Patina, shown here at the top left with an attractive mix of yellow, olive and brown. Secondly, a traditional favourite, Kent Pride, shown at the bottom left.
Note that all of these irises and more are available though mail order on the
nursery website
