Intermedia Grosso - 9cm pot

Go big or go home. Grosso is the largest and most fragrant lavender we sell.

Best for

• Big, bold borders and large sunny spaces
• Long boundary hedges
• Cutting and drying, thanks to its long stems
• Feeding the bees all summer

The lowdown

• Lavandin (Lavandula x intermedia), a vigorous hybrid
• Long purple flower spikes with a powerful scent
• About 80cm tall with a wide, spreading habit
• Plant 3 per metre, as it needs elbow room

Keeping it happy

Give it the sunniest spot you have and soil that drains quickly. If your ground is heavy clay, mix in a few handfuls of grit or sharp sand first; lavender likes it lean, and neutral to chalky soil suits it fine.

Soak it once a week for roughly the first three weeks while the roots settle. After that, put the hosepipe away and only water in a long, dry spell: soggy roots are a bigger threat than drought. Once the flowers fade, clip it back into a tidy mound. Stop where there are still green leaves, because bare brown stems rarely sprout again.

Lavandins are hardy too, so it can stay in the ground all year. Sold as a culinary herb, so you can use the flowers in the kitchen.

What arrives
