Japanese Iris Imperial Velvet
Collection from Cressy only as the plants are now in active growth.
This variety has massive blooms, sum as large as 15cm x 15cm! Japanese irises are another iris that is very easy to grow. They require a minimum of six hours of sun a day. Grow in moist, well-drained soil that is more on the acidic side. Their natural habitat is stream banks where the soil remains constantly moist however they are not pond plants. I grow mine in pots placed in ponds where I ensure their crowns remain above the water line, I also have them growing moist soil and in my bog garden. 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. However, I do not fertilise mine that are growing in pots placed in a pond or in a bog garden. These plants are growing in environments that are rich in nutrients.
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.
