Iris
'How Audacious'
Siberian iris
During late spring and early summer, the spectacular flowers of Iris siberica 'How Audacious' open to create a magnificent display, and they’ll create a real talking point with their amazing colour combinations. Starting at the centre of each bloom, you will see a lovely lime-yellow transcending into white, and then to a royal blue, before eventually becoming a dramatic vivid purple, often with thin, white, slightly ruffled edges. The central petals (or standards) of Iris siberica 'How Audacious' are purple.
This Siberian iris, with mature stems at a height of around 70cm, is the perfect perennial for adding elegance and charm to borders, containers or at the edge of a pond or stream. And don’t forget these blooms make a stunning cut-flower display as well. How audacious indeed!
The slim and graceful sword-shaped dark green foliage only enhances the elegance of this cultivar. Although Iris siberica 'How Audacious' is best in a rich, fertile soil, Siberian irises generally will perform well in lean or hungry soils, too.

Plant calendar
Remove the packaging straight away, check the compost and water thoroughly if dry. Check the plant’s hardiness before placing it outdoors. Plant into a border or permanent container within a month, choosing the position recommended for the variety. Keep the top of the root ball level with the surrounding soil, firm gently and water well.
Soak the roots in water for three to six hours immediately before planting. Keep any crown, buds or emerging shoots above the water where possible.
Pot most bare roots into 15–20cm pots filled with peat-free multipurpose compost. Large or depth-sensitive roots, including peonies, are often best planted directly into borders.
Arrange the roots naturally without bending them. Cover the roots completely, positioning the crown and buds at the depth recommended for that particular perennial.
Keep pots in a sheltered outdoor position and water whenever the compost begins to dry. Grow on until roots hold the compost together when lifted from the pot.
Plant into a suitable border or permanent container once well rooted. Add a label and water regularly throughout the first growing season while the perennial establishes.
