A vigorous hybrid lavender with large, fragrant purple flowers and gray-green foliage. Highly productive for cutting and essential oil production.

Why grow it

Lavandula ×intermedia 'Phenomenal' is a larger and more cold-hardy hybrid than many French lavender cultivars, making it suitable for zones where English lavender struggles with humidity. It typically produces longer flower spikes than common English lavender, which justifies its use in commercial cutting and oil production systems. The vigor and flower yield make it a practical choice where consistent harvest is desired, though standard English lavender may perform adequately in less demanding applications.

Watch out for

Like most lavenders, this cultivar prefers well-draining soil and can decline or succumb to root rot in clay-heavy or consistently moist conditions. Overly rich soil or excessive nitrogen fertilizer can reduce essential oil concentration and create soft growth prone to winter damage. Flowering and oil quality depend heavily on full sun exposure, so performance degrades noticeably in partial shade or humid climates with poor air circulation.
