Dear Kevin,
pepper or Piper nigra (um) (can't remember which ending) is a tropical climber and will grow in this country if you are prepared to keep your greenhouse heated to 18 centigrade over winter.
They have some in most botanical gardens if you wish to go and see.
Regards Sally Wright.
You have a nursery or garden of pepercorn I noticed that you have so much knowledge about it so I want to know it if you have then please suggest me I want to purchase it for my restaurant.
