About Sidonie Lavender
Botanically, Lavandula x allardii 'Sidonie' is a fast-growing shrub in the Lamiaceae family. It reaches around 1 m tall and 1 m wide at maturity, with evergreen, silver-grey and aromatic foliage. Purple and blue flowers appear for much of the year.
Where to grow Sidonie Lavender
Sidonie Lavender suits Mediterranean, warm-temperate and subtropical climates and grows best in full sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot. It also is a genuinely water-wise choice and tolerates salt-laden coastal winds.
Soil & planting
Sidonie Lavender does best in free-draining and sandy soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Sidonie Lavender handles dry conditions well once established. A light spring feed is usually enough to maintain steady growth. During the first growing season, water deeply whenever the upper soil begins to dry, then reduce the frequency as roots establish.
Pruning & care
Prune Sidonie Lavender after flowering to keep it compact and encourage the next flush of blooms. Once established, it is low maintenance.
Using Sidonie Lavender in the garden
Sidonie Lavender earns its place for feeding bees and pollinators, its fragrance, a feature or specimen planting and cut flowers for the vase.
Companion planting & design
For easier irrigation and care, group Sidonie Lavender with species that also favour dry conditions once established and Mediterranean climate. Leave enough room for the mature spread so neighbouring plants are not crowded out.
Good to know
It is regarded as non-toxic and pet-safe.
