Description
The 'Gusto' Japanese Iris has 15cm (6in) diameter flowers, white, widely striped with pastel blue on the periphery. They bloom in late summer at 80cm (32in) in height for 3 good weeks between June and July.
The better-known Iris ensata are the name of Japanese Iris which are very different from our classic garden irises. They live in full sun or partial shade, in moist to wet soils. The 10 to 15cm (4 to 6in) diameter flowers are composed of 3 large flat sepals surmounted by 3 finer petals.
Often cultivated on the banks of ponds and basins, Iris ensata, like many marsh plants, can live with their "feet" in the water during the summer but do not tolerate being submerged during the winter, especially if it is freezing. Plant them in heavy soil forming a slight depression, at the bottom of a slope or on a bank where the soil becomes humid by capillarity.
Grow Iris ensata in moist soil with Astilbes, royal ferns, loosestrifes, and Ligularias.

Planting and care
Iris Ensata prefers a damp and marshy soil, without limestone. They also tolerate a fresh soil, even if it is not waterlogged, as long as it does not dry out in summer. On the other hand, they prefer a rather dry soil in winter. We have planted them near an artificial stream, with the water level kept high during the summer. In winter, we let the level drop by about 15cm (6in), so that the stumps are above the water, as in nature where the level of rivers decreases in winter and rises again in spring with the melting of snow. Their cold resistance is excellent up to about -18°C (-0.4°F). It is further increased if the soil is dry.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
