Planting and care
They thrive in a damp and marshy soil, without limestone. They also tolerate a fresh soil, even if not waterlogged, as long as it doesn't dry out in summer. On the other hand, they prefer a rather dry soil in winter. We have planted them near an artificial stream, which maintains a high water level during the warm season. In winter, we let the water level drop by about 15cm (6in), so that the stumps are above the water, just like in nature where river levels decrease in winter and rise again in spring with the melting of snow. Their cold resistance is excellent up to about -18° (-0.4°F). It is further enhanced 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).

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.
