Trevir.) is an aromatic, perennial, evergreen creeper of the mint family, Lamiaceae, native to Europe and southwestern Asia but introduced to North America and now common in most regions other than the Rocky Mountains. Its common names include Alehoof, Creeping Charlie (or Charley), Catsfoot (from the size and shape of the leaf), Field Balm, Run-away-robin, Ground Ivy, Gill-over-the-ground, and Tunhoof. It is also sometimes known as Creeping Jenny, but that more commonly refers to Lysimachia nummularia. It can be identified by its round to reniform (kidney or fan shaped), crenate (with round toothed edges) opposed leaves 2-3 cm diameter, on 3-6 cm long petioles attached to square stems which root at the nodes. It is a variable species, its size being influenced by environmental conditions, from 5 cm up to 50 cm tall. from wikipedia ( dutch name: Hondsdraf)
