Dutch Lavender - Lavandula intermedia 'Grosso'

• Lavandula 'Grosso' is a hybrid lavender selected for exceptional oil production, producing tall dark violet-purple flower spikes with a rich, intoxicating fragrance from spring through summer and into autumn.
• This fast-growing evergreen shrub forms a beautifully rounded mound of fine, aromatic grey-green foliage that is attractive year-round, even when not in flower.
• Highly drought tolerant and wind hardy, 'Grosso' thrives in full sun in any well-drained soil with low water requirements once established, making it ideal for low-water and coastal garden designs.
• The long-stemmed flower spikes are outstanding for cutting, drying, and use in pot-pourri, making 'Grosso' as useful in the home as it is beautiful in the garden.
• Growing to approximately 80cm tall and wide, it is perfectly sized for use as a garden border, low hedge, container plant, or mass planting that attracts butterflies and fills the garden with fragrance.

Plant 'Grosso' in a row at 50 to 60cm spacings for a classic fragrant lavender hedge that provides a stunning purple display from spring through autumn. Use it as a repeating border plant along pathways, driveways, or garden edges for a formal, structured effect with incredible seasonal fragrance. Mass plant on a sunny slope or bank for a low-water, low-maintenance groundcover that is as beautiful as it is practical. It also works beautifully in large containers on balconies, courtyards, and rooftop gardens where the fragrance can be enjoyed up close.

Q: What makes Lavandula 'Grosso' different from other lavenders? 

'Grosso' is a hybrid variety specifically selected for its exceptional essential oil production and outstanding garden performance. It produces larger, longer flower spikes than many common lavender varieties and has a particularly rich and intense fragrance.

Q: How do I keep my 'Grosso' lavender looking full and healthy? 

Regular pruning is the key. After each flowering flush, cut back by approximately one third into the green foliage, never into old woody stems. This prevents the plant from becoming open and leggy in the centre and encourages fresh, fragrant new growth season after season.

Q: Can I use Lavandula 'Grosso' as a hedge? 

Yes, it is an excellent hedging plant. Plant at 50 to 60cm spacings for a dense, fragrant hedge and trim lightly after each flowering flush to maintain a neat, compact form.

Q: Is Lavandula 'Grosso' suitable for coastal gardens? 

Yes, it has high wind tolerance and performs well in coastal and exposed garden positions, making it a reliable and beautiful choice for seaside gardens.
