Hi Judy,
" Is it worth growing the seeds even tho this is a hybrid? "
Definitely. The variety was created by hybridization, but its seeds are now commercially produced by open pollination. So I think you will be very pleased with the results of using seeds saved from your Zahara Sunburst. They should be the same as your originals. Even if you have other Zaharas around and bees do some cross pollination for you, the results should be very similar, and you might not even notice the accidental hybrids.
