Plant description:

Modern irises have few rivals for colour and form in the herbaceous border. They are among the easiest plants to care for; in fact, they are so easy and rewarding that a few clumps or drifts (long, informally shaped clumps) are a must for virtually any garden. Irises generally do best in areas with a high summer rainfall, such as the highveld, the mist belt of the KZN Midlands and the eastern Free state. They are not well suited to the hot, humid conditions of coastal KZN and the Lowveld. In drier areas, they need year-round watering and, in the southwestern cape, they should be watered regularly in summer. The Iris genus is complicated to explain, but the primary difference between the groups is their root systems. Irises can be bulbous (having an actual bulb); tuberous (a cluster of fleshy, brittle, tuberous roots); or rhizomatous (a rhizome with attached feeding roots). The majority of irises are rhizomatous and are propagated by division. Falling into this category are the water-loving beardless irises and those long-stemmed beauties, the bearded irises.
