About Hibiscus syr. Oiseau Bleu 4 Litre Pot 40-60cm

Hibiscus syriacus ‘Oiseau Bleu’ – Exotic Summer Colour

Hibiscus syriacus ‘Oiseau Bleu’, also known as the Blue Bird Hibiscus, is a hardy deciduous shrub admired for its exotic-looking flowers and long flowering season. From mid to late summer, this striking variety produces an abundance of large, trumpet-shaped blooms in rich violet-blue, each with a contrasting deep red centre. These spectacular flowers bring a touch of the tropics to the garden, just when many other plants are beginning to fade.

Its lush green foliage creates a dense, upright form, making it ideal for hedging, screens, or as a standalone feature. Growing to around 2–3 metres in height and 1.5–2 metres in spread, ‘Oiseau Bleu’ is perfectly suited to both large and smaller gardens where reliable, late-season colour is desired.

Tough, low-maintenance, and highly adaptable, Hibiscus syriacus thrives in most well-drained soils and enjoys a sunny, sheltered position. It is also very attractive to pollinators, making it a valuable addition to wildlife-friendly gardens.

  • Exotic Flowers – Striking violet-blue blooms with deep red centres.
