It's a description that we'll never read on a commercial seed packet.
I think the people who write blurbs for places like Burpee and Parks listened to too many episodes of Lake Woebegone, where all the children are above average.
If I believed their catalog and packets, EVERY variety they sell is the most popular, has the best flavor, and is the easiest to grow. Of course, they sometimes forget to mention things like "needs stratification" or "slow and irregular germination".
