Wake up to lavenders

Lavenders offer more variety than you might think – with a range of hues and a long flowering season, says Esther McMillan

Flower show exhibit by Downderry NurseryLong associated old ladies’ toiletries, lavender has suffered from a staid reputation and an image that verges on the twee. But these plants have a place beyond fusty drawer liners and the traditional cottage garden. You can select cultivars that spread flowering throughout the summer season and plant in modern drifts, reminiscent of Provence.

As well as colour and scent, lavender adds an animated dimension – it teems with bees thronging around its nectaries. Their hum may not be the sound of cicadas, but lavender brings the breath of the south with it. Below is a selection of Award of Garden Merit winning lavenders that you could inhale at home.

They are divided into different groups:

Early flowering

The species L. angustifolia has produced many medium-sized cultivars that are often used for hedging. The most commonly grown is 'Hidcote'. These so-called 'English' lavenders flower from midsummer until the end of July, sometimes flushing again. Their flower heads are generally more rounded than L. × intermedia selections and the foliage is a greeny-grey. Commercially, they produce the highest-quality essential oil from glandular hairs. Hardy thoughout most the UK. RHS hardiness rating H4.

Later summer flowering

Lavandin, L. × intermedia and its selections, are taller shrubs with more elongated flowerheads and silver foliage. They flower from mid July until the end of August. Lavandin is a hybrid between L. angustifolia and L. latifoliaIt is more tolerant of acid soil than L. angustifolia. Hardy thoughout most of the UK (H4).

French lavenders

Easily identified by a headdress of perky sterile bracts, L. stoechas and its selections need sheltered, sunny sites. They flower in flushes from late May until end of August. Hardy-ish, but they need a favoured site (H3-4).
