With its intoxicating fragrance, silvery foliage, and purple spikes, lavender is one of the most beloved perennials among Quebec gardeners. Originally from the Mediterranean region, this plant from the Lamiaceae family is as appealing for its decorative aspect as for its ability to attract pollinators while repelling deer and rabbits. Here is an overview of the varieties to prioritize, as well as our planting and maintenance tips to enjoy flourishing lavender season after season.
Three Lavender Varieties to Highlight
Known for its spectacular blue-violet spikes and strong aromatic fragrance, 'Hidcote Blue' is a compact and rounded English lavender that reaches about 30 to 45 cm. It loves full sun and poor, rocky, or sandy soil, as long as the drainage is perfect. Hardy in zone 5, it naturally repels deer and hares and is wonderfully suited for borders, rock gardens, and dried bouquets.
A garden classic, 'Munstead' forms a compact and rounded clump of about 45 cm, with silvery-gray foliage and highly fragrant blue-mauve spikes that attract bees en masse. It prefers light, sandy, and well-drained soil, tolerates drought and urban pollution very well, and is perfect for borders, flower beds, and container growing. Its exceptional hardiness (zone 4) makes it a reliable choice for most Quebec gardens.
'Sweet Romance' Lavender
With its particularly dark purple spikes and intense fragrance, 'Sweet Romance' offers an early and abundant bloom from early summer until September. Its silvery foliage forms a dense cushion of 30 to 45 cm that contrasts beautifully with its dark flowers. Like other lavenders, it requires full sun and soil that dries well between waterings; pruning after the first bloom can even encourage a second wave of flowers later in the season.
Properly Planting Your Lavender
All lavenders share the same basic requirements: full sun and very well-drained soil. Choose a location that receives at least six to eight hours of sun per day and avoid heavy, clay soils where water stagnates, as moisture at the collar is the main cause of plant decline. If your soil is compacted, improve it by incorporating coarse sand, gravel, or good potting soil. The Passion Jardins planting soil, enriched with compost and designed for flower beds and shrubs, provides an excellent base for improving soil structure and drainage before planting. Space the plants about 45 to 60 cm apart to ensure good air circulation around the foliage, which limits the risk of fungal diseases.
Lavender Maintenance Throughout the Seasons
Watering and fertilization: once well established, lavender remarkably tolerates drought and even prefers soil that dries between waterings. It requires little or no fertilizer, but if you grow your lavenders in pots or in very poor soil, a phosphorus-rich bloom fertilizer, like 7-14-14, applied at the beginning of summer can stimulate more abundant flowering. In spring, a light layer of well-matured compost, such as Solmer compost, can also be incorporated into the soil to enrich it without excess, while improving its water retention capacity in sandier soils. Pruning: cut back each plant by about a third in early spring to stimulate dense growth, avoiding cutting into old wood without leaves, which does not always regrow. After summer flowering, cut the faded stems; this keeps a compact shape and can even encourage a second bloom in some varieties like 'Sweet Romance'. Winter protection: the main enemy of lavender in winter is moisture, not cold. Ensure impeccable drainage, avoid organic mulch that retains water near the collar, and instead favor mineral mulch (gravel, crushed stones) or a good cover of natural snow to protect the roots from extreme cold.
By choosing a variety suited to the intended use, providing it with a sunny and well-drained location, and simply avoiding over-fertilization and watering, lavender will reward your garden with its generous flowering and inimitable fragrance for many years.
