I am planning to create a small bed of bearded irises. I have tried planting them in a mixed border before and, although they put on leaves they have never flowered - this is after 3 years. I have been told that they prefer to be in a bed without other species - is this true? There is a very tempting offer at Thompson and Morgan at the moment, but I'm unsure whether buying rhizomes - albeit very cheaply - in December is a good idea. Would they store well over Winter and when should I plant them? Sorry for all the questions , but I am a newbie to growing bearded irises but I really love them and want to have them in my garden.
