The scent of Lavender Spica (Lavandula latifolia) is stronger, with more camphor than Lavandula angustifolia (i.e. English Lavender or Hidcote Blue) scent. The amount of essential oil in the plant is also higher.
Lavandula latifolia is a strongly aromatic shrub growing to 30–80 cm tall. The leaves are evergreen, 3–6 cm long and 5–8 mm broad.
Lavender Spica, known as broadleaved lavender, spike lavender or Portuguese lavender, is a flowering plant in the family Lamiaceae, native to the western Mediterranean region, from central Portugal to northern Italy (Liguria) through Spain and southern France.
Spike Lavender is also known as Spanish or Portuguese Lavender and is used a great deal commercially in Lavender perfumes, soaps and laundry products.
The flowers are pale lilac, produced on spikes 2–5 cm long at the top of slender, leafless stems 20–50 cm long.
Lavender is generally used in herbal remedies for headaches, depression and insomnia. Also, the dried flower heads can be used for such purposes. It is useful for perfumes, sachets and oils too.
