Dutch Iris are exotic and hardy plants perfect for late spring colour. As one of the tallest spring bulbs available they are ideal for planting at the back of beds and borders. They look best when planted in groups or ribbons, like most spring bulbs they look a bit lonely on their own. Their straight stems are also excellent for picking.
The foliage of Dutch Iris is mid green, narrow, and upright. It is the perfect complement to the blooms and easy to weave into almost any garden scheme. You can even grow them in large containers or pots.
Dutch Iris are delightfully hardy bulbs which will easily naturalise to give you years of increasing colour. Plant 10-15cm deep in any well drained soil.
Water Dutch Iris to establish, then you only need bother if rainfall is low during their growth – as most of Australia experiences natural rainfall though autumn/winter they are usually self sufficient. Climates south of Sydney/Perth and the Qld Tablelands are best. They become dry tolerant as they mature. Keep relatively dry during dormancy. Choose a spot with at least six hours of sun a day – in warmer climes half a day is just ok. Fertilise with a general purpose fertiliser annually when they are in bloom.
Allow foliage to stand after flowering. You can cut it back once it has yellowed and the bulb goes into dormancy. Dutch Iris are relatively trouble free, but it is a good idea to protect new growth from slugs and snails, and keep an eye out for aphids as the weather warms up.
If you are pushed for space in the garden try companion planting your Dutch Iris with salad greens in the veggie plot. You can pick the blooms and harvest the leaves at the same time. Plant more greens as needed and they will help hide the fading foliage.
