Were it receives bitterly cold frosty winters and hot dry summers. My winter flowering Iris is planted close to deciduous trees in fairly poor soil which, this plant is known to like. It gets quite a lot of shade during the summer and not a great deal of water. This rhizomatous flowering plant has evergreen grassy leaves and violet blue flowers. The clump of leaves grow, to a height of 12 – 15 inches and nestled deep, within the long leaves, are the pretty violet blue flowers that can be seen growing on short stems. The flowers mainly appear during winter and early spring. The Unguicularis Iris flowers have 3 large fall petals and 3 standard petals. The flowers are 5-8cms in width and are a good addition to make your winter garden colourful. They are well suited to mild winter conditions too, this means they will grow well in many other states and regions of Australia. They flower with the kniphofia var winter cheer, daffodils and snow drops. The flowers are scented and have a fine yellow marked beard with white netting both sides coming from the throat of the flower. These tough plants make good cut flowers and grow well in garden borders. The cut flowers can last for 4-5 days in a vase. Iris unuicularis form stunning garden beds, wall side borders or can be grown in near any sort of container because of their shallow root system. The ingestion of the plant parts can cause severe discomfort, as the plants are poisonous.
