Sorry, Hilary. David picked up the majority of the hints. Not wild, feeling at home, ie domesticated (domestica). Looking east and upwards - the plant comes from the east, look up into the heavens. Similarly Venus being a celestial (heavenly) body. The grass track - bamboo is in the grass family. I know that Nandina isn't but I did stipulate the common name. I thought that the bamboo in bamboozle might be picked up. Well done, David.
