“Singular and beautiful colour”

“Irises have been compared to Orchids, and those who delight in singular and beautiful colour, and to whom greenhouses and hot-houses are denied, may find a substitute for Orchids in irises”

By William Robinson, from “The English Flower Garden,” 1892

Our Species

We all begin with a love affair and for most it is with the Tall Bearded Iris which comes in all hues except a true red and green, however the search to perfect these colours in the Iris continues today as it has done for the past 80 odd years.

Below you can see examples of New Zealand Irises.

Arils and Aril Bred Irises

The common characteristic of these very different species from which the term “aril” arises is a white appendage on one end of the seed. This appendage or aril varies in size in each species.

Tall Bearded Irises

It is a large genus containing, among several sub-genera, bearded or pogon iris, the most popular and most frequently grown iris. Thousands of named varieties have been developed over the last 100 years or so, in a wide range of colours and sizes.

Beardless Iris

There is a growing interest in the non bearded irises. Including these in your garden will extend the flowering season over almost the whole year.
