I ordered mine from Hortico two years ago and it's a beauty! Ordering from Hortico is always risky, however, so I hesitate to recommend it.
Pickering's prices are so low that they can't accommodate special license or patent fees. That's why they have some roses that can't be shipped to the United States. Other nurseries either charge a little more for those roses or absorb the cost of those fees by charging higher prices across the board.
