Etymology

[edit]

Thespecies nameangustifolia is Latin for "narrow leaf".[4] Previously, it was known asLavandulaofficinalis, referring to its medicinal properties.

Cultivation

[edit]

English lavender is commonly grown as anornamental plant. It is popular for its colourful flowers, its fragrance, and its ability to survive with low water consumption. It does not grow well in continuously damp soil and may benefit from increased drainage provided by inorganic mulches, such as gravel. It does best inMediterranean climates similar to its native habitat, characterised by wet winters and dry summers. It is fairly tolerant of low temperatures, and is generally considered hardy toRoyal Horticultural Society zone H6, orUSDAzone 5.[5] It tolerates acid soils, but favours neutral toalkaline soils, and in some conditions it may be short-lived.[6]
