Lavander
Lavender is a perennial semi-shrub, 30-60 cm heigh and 60-80 cm width, with silvery gray leaves and light blue, purple and mauve coloured flowers. It prefers being in full sun, but real lavander is rustic: it withstands temperatures well below zero.
Plant the lavender in a light soil, well drained, even poor, rocky or limestone. It tolerates drought, so water lightly.
Multiplie lavander by layering, or by cuttings (in late summer or spring - it's very easy), and divide it into several pieces when it becomes too large.
Cut lavander in the summer, at the end of the flowering. You can rejuvenate an old lavender by cutting it severely in spring, when the vegetation begins.
Harvest the lavender stems and dry them upside down in a dry and warm place. Use these bouquets of lavender (or change them into medleys) to perfume your house and your cupboards.
Lavander is an anti-moth and anti-mosquito.
Watch out: the infusion of lavender flowers becomes toxic at high doses!
