so is it really as hard as I've been reading to start rosemary from seed? I love adding this herb to veggie foil packs that I grill. I usually buy the fresh herb but would like to start several of the plants from seed since herbs are freaking pricey at nurseries. however, if I buy seeds and they don't sprout, I'd rather just buy plants. I'll have a seed starting bed warmer and grow lights if that helps any?
