It seems that everyone loves lavender. I wasn't convinced until I started growing it, and now I'm absolutely sold. These small aromatic shrubs make excellent hedging, the edge border beautifully and they attract so many bees!
Lavender needs lots of sun and good drainage to keep them happy. To prevent them becoming woody and leggy I would recommend cutting back every year after flowering, make sure you cut back to green (not brown) as they will not regrow from old wood!
