Description
Very close to Cyperus alternifolius, a native to Madagascar. The stiff stems with triangular cross-section, emerging from the rootstock, bear at their tip a crown of 10 to 20 linear leaves, narrower than those of C. alternifolius, but wider than those of C. papyrus. In late summer, a crown of small white-greenish flowers appears on long pedicels. A beautiful and highly graphic species that adds a lot of character to a small water feature.

Planting and care
This species can only be grown outdoors in the ground during winter in the mildest regions, as the rootstock must never freeze. However, we have successfully cultivated it in a large pot submerged under 20cm (8in) of water for several years, as it is very rare for ice to exceed 15cm (6in) in thickness in our ponds. In this case, the foliage completely disappears in winter, but it regrows without any issues in spring. The very "vigorous" rootstock cannot tolerate being confined for too long in a too small pot, which is why pot cultivation requires dividing the stump and repotting it every 3 years or so.

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).

The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:
- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- 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.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).

- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
