Iris laevigata, known as Japanese iris,
It is found growing in shallow waters and seems to prefer marshy and still ponds, although it can also be grown in damp soil if conditions are right. Flowers are usually blue, purple or violet and have unique colour patterns including some types with predominantly white flowers with blue spots (washino-o), and dark purples bordered with white (maikujaku).
Synonyms include I. albopurpurea and I. phragmitetorum.
Cultivation
Iris laevigata differs from other Japanese irises mainly in being more dependent on water and in lacking the strong midrib of the foliage. When grown from seeds, it usually germinates in 30–545 days although even under good conditions germination may be erratic. Seeds are sown about 6 mm deep in a peaty seed sowing mix at about 15–20 °C with frequent watering. Some varieties are almost ever-blooming even in mild climates, which makes it a good candidate for water gardens in temperate zones.
This plant has been cultivated in Japan for more than a thousand years and some varieties mentioned in Japanese gardening books in the late 17th century are still in existence.[4]
The variegated cultivar I. laevigata 'Variegata'[5] has gained the Royal Horticultural Society's Award of Garden Merit.
