Living with Lavender

Many of us have a love-hate relationship with lavender; on the one hand we appreciate its beauty and fragrance but then we experience its often short-lived nature and get frustrated. In either case there is no denying the breathtaking grandeur of a mass planting of Lavandula in full bloom and its other role as an important pollination plant becomes self-evident with the many bees and butterflies appreciating it right along with us. Regardless of its standing in your garden, lavender in flower continues to be a top seller at the garden centre and often heralds the arrival of summer. With that in mind I thought that I would provide you with an overview of the genus, including some tips on planting and pruning.

What Lavender Needs

Most of the hardy cultivated species are native to the Mediterranean and North Africa, so a full sun exposure is best with a minimum of 6 hours during the summer. Of equal importance is good drainage and poor to moderately fertile soils, as heavy clay tends to rot the root system during our wet winters and those with large amounts of compost or organic matter overfeed, resulting in floppy lavender. A light hand with the fertilizer (particularly nitrogen) is also beneficial, as this genus is used to lean, slightly alkaline soils (pH 6.7-7.2) – so you can add a little dolomite lime at planting time if you feel your beds are acidic. Pruning is another essential in order to keep your plants in good form, with a light contour cut in spring (along with the removal of any dead wood) followed by another just after the flowers have faded. The latter allows some of the essential oils to be left in the flower buds on the harvested stalks of either English Lavender or Lavandin for potpourri or culinary use. Spanish Lavender (Lavandula stoechas) blooms a bit more sporadically and you can deadhead individual flowers as they fade but the cardinal rule of pruning it is to never cut into old wood, as they seldom recover. Lavender is also extremely deer resistant and attracts a multitude of pollinators.

Lavandula angustifolia 'Hidcote'

Lavandula angustifolia or English Lavender is the hardiest species at USDA zone 5 and in my opinion has the best longevity. It tends to be the most compact, averaging 24” high, with dwarf varieties such as ‘Blue Cushion’ growing 12-16” tall. The most common cultivars include ‘Hidcote’, ‘Munstead’, ‘Essence Purple’, ‘Loddon Blue’ and ‘SuperBlue’, although there are several colour options including white (‘Nana Alba’, Ellagance Snow’), pink (‘Rosea’, ‘Jean Davis’, ‘Hidcote Pink’), lilac (‘Melissa Lilac’) and even variegated foliage (‘Platinum Blonde’). For those of you on a budget, try growing ‘Lady’ from seed as it usually ends up blooming in its first year. Organically grown flower buds can be used for cooking, with my daughter’s lavender aioli served on barbeque lamb chops being one of my favourite dishes.

Lavandula stoechas has large showy blooms that much resemble a caterpillar’s body with a tufted wing or bract on top. They generally start blooming mid to late spring and will continue to do so sporadically throughout the summer with regular deadheading. It tends to grow a bit taller (24-30”) than English lavender and at USDA zone 7 can prove unreliable during cold winter weather. The most widely available varieties include ‘Otto Quast’, ‘Anouk’ and ‘Luxurious’ with colour variations including pink (‘Bandera Pink’, ‘Pink Summer’, ‘Strawberry Ruffles’), rose (‘Anouk Deep Rose’), white (‘Ballerina’, ‘White Anouk’) and even contrasting silver foliage (‘Silver Anouk’). The high camphor content means that Spanish lavender is inappropriate for culinary purposes but that also makes it even more deer resistant.

Lavandula x intermedia is a naturally occurring cross between English lavender (L. angustifolia) and Spike or Portuguese lavender (Lavandula latifolia). In France it is grown commercially to produce essential oils for medicinal use and fragrances (perfume, cosmetics), as well as the flower buds being one of the main ingredients in Herbes de Provence (a blend of dried thyme, rosemary, oregano, savory, marjoram and lavender buds). ‘Grosso’, ‘Phenomenal’ and ‘Provence’ are the most common cultivars, with the white flowered ‘Alba’ occasionally finding its way to market. Lavandin grows quite tall at 3’ and blooms about a month after the English, usually July to early August and is hardy to USDA zone 5.

The Rarities

Lavandula dentata / French Lavender

Over my twenty years of being a nursery manager I seen a few rarities come and go, with the main reason they’re not offered on a consistent basis being hardiness. French lavender (Lavandula dentata) is a good example of this with his lemon scent and beautifully notched foliage, but at USDA zone 8 it stands little chance of surviving the winter, even here on the coast. Lavandula x chaytoriae is a bit hardier at zone 7 and this hybrid of lanata and angustifolia bears purple blooms over silvery foliage, with the most common cultivar being ‘Sawyers’. Fernleaf Lavender (L. pinnata Z9) is native to the Canary Islands with bluish-purple multiheaded bloom spikes over lacy silver foliage and is very similar in appearance to the equally tender Lavandula multifida. Green Lavender (L. viridis Z8) rounds out our list of rarities with pale yellow to greenish-white flowers similar in structure to Lavandula stoechas.

Companion Plants for Lavender

Lastly I’d like to leave you with a short list of perennials that bloom around the same time as your lavender and really complete the overall flower display. First up is Coreopsis verticillata ‘Zagreb’ with its chrome yellow flowers and fine textured foliage, a perfect companion for ‘Hidcote’. For background purposes both Achillea x ‘Moonshine’ with its contrasting silver foliage and lemon yellow blooms or the white variegated Veronica longifolia ‘Charlotte’ also both provide a nice compliment to the purple lavender blossoms. Sedum rupestre ‘Angelina’ is a perfect choice for a foreground planting with its bright gold, needle-like foliage and it is equally drought tolerant.
