Iris of Sissinghurst have just added a number of images of their current stock to their website. New images include the gorgeous Black Out, and almost 30 others. See their blog and website for details and more images.
A recent article in the Times newspaper (4th April) covered the RHS London Flower Show. The Iris of Sissinghurst nursery featured in the article for their "exquisite collection of small-flowered, short-stemmed irises" including the pure white Lilli shown here.
