Irises are a vast genus of plants, ranging from the diminutive rockery varieties, to imposing border specimens. Some are grown from bulbs, others from thickened underground stems known as rhizomes. Nearly all, however, share the same beautiful and easily recognisable flower form – 3 erect inner ‘standard’ petals and 3 hanging outer ‘fall’ petals.
Hints and Tips
A bed of irises bulbs can look stunning but can often clump together and look overcrowded. It is relatively easy to spread your irises out by lifting the entire clump with a garden fork in late summer. You can then separate the new sections from the original with a knife then replant.
