Spuria Iris Yellow & White
These are the tallest growing irises reaching a height of 1.5m but there are also dwarf varieties available. These are statement plants and are stunning in flower which is from the end of spring to mid summer. They prefer a sunny position but can handle some shade and well drained alkaline soil that is rich in organic matter. Spuria irises prefer a dry summer but mine handle being watered during summer. Maintenance is simple, remove dead foliage in autumn and mulch. This is also a good time to fertilise with a nitrogen-rich fertilizer and again in spring.
How to Harvest Iris Flowers
Harvest your flowers early in the day. Choose buds that are just beginning to open rather than flowers that are fully open. These buds will open within a few hours with the rest of the buds on the stem opening over the next couple of days. Place your flowers in a bucket of tepid water until you are ready to create your arrangement. When you are ready to arrange the iris flowers, re-cut the stems about 2cm above the original cut at an angle under water. Remove spent flowers immediately. Take care as some irises colours will bled and can stain. Check the water level of your vase often and top up as required. Replace water and recut stems every second or third day. Place your vase in an area that is cool and away from direct sunlight and drafts.
