Hibiscus 'White Chiffon®' (Hibiscus syriacus) - flowering shrub - 19 cm pot - Height 90 cm

TheHibiscus syriacus White Chiffon® is one of the deciduous shrubs with the latest and longest bloom in the garden: it generally starts in July and continues until the first frosts of October. Each flower is ephemeral and lasts only one day, but the shrub produces them continuously in impressive quantities throughout the summer. This uninterrupted succession of large pure white flowers makes it an essential star when most other shrubs have finished blooming. Full sun is the key to obtaining this floral abundance: a shaded location will significantly reduce the number of flowers.

Yes, theHibiscus syriacus White Chiffon® is a fully hardy shrub, capable of withstanding temperatures down to around -15°C, making it suitable for the vast majority of French territory, including regions with cold winters. When planted in the ground, no special protection is required in hardiness zones H1 to H5. In a pot on a terrace, the growing medium is more exposed to frost than the soil in place: it is therefore advisable to wrap the pot in a winter fleece and move it closer to a south-facing wall during the coldest spells.

The pruning of the l'Hibiscus syriacus White Chiffon® on stem s'hould be done at the end of w'inter, between February and March, before the first buds begin to swell. T'he goal is to shorten the branches from the p'revious year by half to two-thirds of their length, cutting just above a well-formed bud facing outw'ards. This short and regular pruning stimulates t'he growth of many new branches that will bear the flowers of t'he summer.

Yes, l'Hibiscus syriacus White Chiffon® is particularly suited to container growing on a balcony or terrace, d'especially in its grafted stem form, which gives it a compact and highly decorative shape. Choose a pot d'at least 30 to 40 cm in diameter with effective drainage (holes at the bottom, layer of clay b'eads). Use a quality substrate slightly enriched with perlite to prevent excess m'isture. W'atering in a pot must be more careful than'in the ground: check the'moisture of the substrate every two to three days in summer.

TheHibiscus syriacus White Chiffon® adapts to a wide range of soils, but thrives ideally in well-drained, slightly acidic to neutral soil (pH 6 to 7), loose and rich in organic matter. It tolerates lightly alkaline soils but will struggle in heavy, clayey, poorly drained soils. At planting, incorporate a good amount of mature compost or decomposed manure to improve the structure and fertility of the soil. Provide an organic mulch 5 to 8 cm thick at the base of the plant to limit evaporation, regulate soil temperature and suppress weeds.

L'Hibiscus syriacus White Chiffon® has moderate water needs once well established in the ground, but it should not be neglected during its first two seasons. At planting time (spring or early fall), water thoroughly with'a bucket of'water every two to three days for the first six to eight weeks. In summer during prolonged heatwaves, even a long-established shrub will appreciate a deep weekly watering rather than frequent light surface watering.

Yes, theHibiscus syriacus White Chiffon® is a plant that is particularly valuable for garden biodiversity. Its large, open flowers with generous corollas are highly prized sources of nectar and pollen for honeybees and wild bees, bumblebees, and butterflies. The long flowering season, from July to October, is particularly welcome because it occurs when many other nectar-producing plants have finished their cycle. Hoverflies, beneficial hoverflies in the garden, are also attracted to its flowers.
