Description
Persicaria amplexicaulis 'JS Caliente' is a stem-clasping perennial renouée variety that is easy to grow and has vibrant colours. Its multiple slender spikes appear from July and continue until October, flooding the borders with a vivid red, between pink and orange. Preferring moist to wet soils, it thrives in full sun or partial shade, creating beautiful, voluminous and wild borders thanks to its deciduous heart-shaped leaves.
Belonging to the family of polygonaceae, the persicaria amplexicaulis is a perennial that owes part of its name to the shape of its leaves. They are called stem-clasping as they embrace or sheathe the stem on which they are attached. Green and deciduous, they are also lanceolate and heart-shaped, turning red in autumn. Numerous, large and of medium size (around 15 cm (6in)), they quickly give volume to the borders. The stems that bear them end in thin spikes made up of multiple small bell-shaped flowers. Those of 'JS Caliente' have a particularly electric hue. Their carmine red is animated with pink and orange reflections and vibrates under the sun. It is a hardy perennial that loves water and requires no monitoring. If the substrate is rich, its rhizomatous stump will colonize the surroundings.
The dense and upright clump of Renouée 'JS Caliente' adds volume to pond edges and enlivens partially shaded borders. It blends easily with all summer plants with natural accents: Astilbes, Grasses, as well as Cyperus longus. Its long flowering period allows you to enjoy its enthusiasm and cheerfulness.

Planting and care
The 'JS Caliente' Knotweed or Persicaria amplexicaulis is an easy and hardy perennial. You can plant it in spring or autumn in full sun or partial shade. It prefers moist to wet and rich soils. If you are concerned about intense heat and drought, make sure to water it during planting, mulch around the base, or deeply cultivate the soil so it can find the moisture it needs. It will thrive near bodies of water or at the edge of woodlands and is not afraid of cold and wet winters. Under certain climates, its foliage may even be semi-evergreen. Maintenance is limited to removing faded or dried stems during the season or at the end of winter, depending on the aesthetic you desire.

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).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- 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).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
