I love this small, bushy, well behaved rose bush. In our yard the buds and blooms are vivid yellow, and they stay that way until their petals fall.

So far this rose has been a champ dealing with the pathetic May and June we've had so far. It's spent most of the year under a steady string of cloudy skies and insistent rains, but I've yet to spot a bit of blackspot. My only treatment is Bayer systemic every couple months, and my daily garden walks with water/detergent mix bottle in hand to hunt for aphids. The color of the blooms so far has been a very pleasing glowing gold color on the verge of orange, not really a bright pure yellow. I hope to hold on to this one for a while.

I have had a Shockwave for two years. It did not grow well the first summer, but it did survive the winter buried in ground, and grew better the second summer. I will see if it makes it through this winter.

The blooms are pretty, but they fade to a paler yellow as they age, and they are not long-lasting. For a yellow it does seem to be quite resistant to black spot. I have it growing about 25 feet from the neighbor's flowering crab that gets completely loaded with black spot every summer, and it does well there. (I do spray my roses weekly for black spot, but the more susceptible cultivars get it anyway.)

I will give a neutral rating until I see how well it does next year.
