Lavandula × intermedia ‘Grosso’ Description

Lavandula × intermedia ‘Grosso’ is a vigorous lavandin forming a broad mound of aromatic silver-grey foliage topped by long stems of deep violet-purple flowers in midsummer. The blooms are highly attractive to bees and are widely used for drying, scented crafts and cut flower work. Mature plants generally reach around 60 to 90cm high in flower and spread broadly with age. Grow in full sun in neutral to alkaline soil with excellent drainage. It tolerates drought once established but dislikes heavy, saturated winter ground. In wetter Irish gardens, raised beds, gravelly soil or containers can improve longevity. Lightly trim after flowering, removing spent stems and a little leafy growth, but avoid cutting hard into old bare wood.
