It seems to be a Prostanthera sp. to me, but not so sure..... I would like to know exactly what species it is. Thanks.
It looks like Rosemary (Rosmarinus officianalis) to me. Does it have fragrant leaves? These will help you tell if it's Rosmarinus or Prostanthera - the first has a piney scent, while the second is more minty. If it is Prostanthera, check out P. phylicifolia and P. linearis. The genus Prostanthera or Mint Bushes, is native to Australia; Rosmarinus comes from the Mediterrenean.
Definitely not Rosmarinus, which has flowers resembling those of a Salvia. http://images.google.com/images?q=r...US:official&client=firefox-a&um=1&sa=N&tab=wi
Looks like Agalinis to me. most probably Agalinis paupercula (Gerardia paupercula, Agalinis purpurea var. paupercula). Where have you seen it?
Well, they are definitely not rosemary. Unfortunately, I don't have the plant now since it's in my parent's house in Pohang, so I can't say exactly what kind of scent it had. However, as I remember of, it's scent was more similar to mint then pine. So, I think it's a Prostanthera. After some searching, now I believe that it's a Prostanthera phylicifolia. Thanks so much every body. sepo, It was being sold as 'Large flowered rosemary(of course in korean)' at the flower market. and the nursery owner told me that they were from Japan. But they were not rosemary for sure, and I know that rosemaries are from Southern Europe so I decided to post it here.
