Stark sells excellent fruit trees, but I've never ordered roses from them. Did you order Sunny Knock Out? It's a single bloom, not double. I love that rose. I am not familiar with the double yellow rose that they are offering this year. It's hybridized by Meilland, which isn't bad, but the Knock Outs come from Radler.
To me, a hedge of Sunny Knock Out in bloom looks like a swarm of butterflies or golden finches. The yellow fades to lighter yellow, then white. It's not a bloom to bring in to a vase, but beautiful mixed in a bed with grasses and wildflowers.
