Lavender is a perennial that thrives in sunny locations in well drained soil. Looks great in a rock garden. Popularly used in containers, but don't use an overly large pot as lavender prefers to be a bit root bound. Well established plants - more than 1 year old - will thrive in dry conditions and can be used to create an engaging border.
Propogate new plants by layering; pull a stem to the ground and simply anchor it under 1" of soil by placing a heavy object on top of it. By the following spring you'll have new plants!
Harvest flowers as young buds, cutting the flowering stem back by 1/2. Tie the stems in a bundle and hang upside down to dry.
Because it is a strong antiseptic, lavender tea, when applied topically, can help heal cuts, wounds and sores. It can also be used to fight bad breath. You can also crush the flowers and use the oil on skin blemishes.
