How to grow lavender plants
Hardy noninvasive perennials, lavenders suit both informal and formal gardens. Mature lavenders form dense mounds of foliage, ranging from grey to green and from 30 to 60 centimetres tall – beautiful even when they're not blooming. And lavender's not just blue – you can choose a plant that flowers in white, pink or pale purple through to inky, intense blue or violet.

In a flowerbed, the blooming plants provide a cloud of hazy colour that softens the contours of leggy companions such as roses. Planted in a row, compact varieties form a low hedge to edge a bed or path, or trace the outline of a traditional knot garden filled with other herbs.

Perhaps the best part? Once you plant lavender, you can enjoy its fragrance – and its flavour – long after summer is gone.

How to grow it
Given a sunny, well-drained site, lavenders will thrive in dry, poor soil and even self-seed. An annual top dressing of compost and occasional watering during very dry spells is welcome, but avoid overfeeding with high-nitrogen fertilizers or rich manures. Follow the spacing recommendations on the plant tag (some lavenders spread up to 1 metre in diameter) when planting in a flowerbed, but shave off about a third of that when planting a row for a hedge. This is a good time to add new lavender to the garden; planting is recommended no later than two months before the first hard frost, to let plants get settled in.

Compact varieties grow happily in containers, but require a coarse potting mix that doesn't stay soggy, and you will need to water, sparingly, in the summer. In the fall, protect the roots from freezing by sinking the pot in a flowerbed for the winter or moving the potted plant into your garage until spring, then repot in fresh soil.

Harvest some or all of the flowers, if you like, or leave them all summer long. Either way, shear back lavenders by about one-third (avoid cutting into older, woody stems) each fall, leaving a compact cushion of leafy stems.
