When it comes to determining if you have a better plant, it is essential that you know and understand the plants that are currently available. New plants must be trialed and compared in side by side tests with the best varieties to know what you have. If you can’t beat the best, then you better keep breeding until you get it right.
This side by side comparison of boxwood is a great example of the power of trialing plants. I’ve been growing and trialing North Star boxwood for over five years. When we first got the plant from its originator Gary Katerberg I was skeptical that his plant could rival the best boxwood varieties available. In fact, I did not give it much of any chance of being introduced. But when we had it in a test bed with twenty other varieties of boxwood, it preformed so well, the results could not be ignored. When you see it side by side with Green Velvet, the number one variety on the market, you can clearly see that it is a better plant. Even during winters with temperatures as low as minus 15 degrees, North Star boxwood shined; the winter and the spring foliage color was so much darker. While Green Velvet turned a pale pea green, North Star boxwood remained very dark. Additionally the plant is very compact, with dense growth, yet at the same time it grows faster than other popular varieties.
Clearly “Seeing is Believing,” and side by side trialing is the only way to find out if a plant is truly better or not. North Star boxwood has passed the test.
