Lavandula × intermedia ‘Gros Bleu’, commonly known as Gros Bleu lavender, (pronounced like Grow Blue) is a standout variety prized for its exceptionally long stems and rich, true purple flower color. Among lavandins, ‘Gros Bleu’ is widely recognized for delivering one of the truest purples available, and that color holds beautifully whether the flowers are used fresh or dried.

This vigorous evergreen shrub forms a well-balanced plant with strong stems rising above aromatic gray-green foliage. In midsummer, it produces an abundant flush of showy flower spikes that create dramatic visual impact in the landscape while also excelling in bouquets, wreaths, and craft projects.

‘Gros Bleu’ is a favorite not only for its beauty, but also for its reliability and performance. It thrives in full sun and well-drained soil, tolerates heat and drought once established, and returns year after year with consistent bloom. For growers seeking a lavender that performs equally well in the garden and in cut-flower applications, this variety is a top choice.
