Konk, I believe it would be classified as a bush. My oldest bushes are about 6' high after 6 years, and I doubt they'll get much higher. The first year you'll get some pod development, but year 2 and on, they really develop and the deer seem to go nuts for them. I have a bunch of 6' wire fence that I placed around the plants the first couple years so the deer wouldn't nibble them down to much. About year 3 you can start taking cuttings and really spread them out on your property to get nice "groves" going. You won't regret planting these! Taz
