That's correct, it's Zizia aurea. It lasts a good ten days if you cut it as it's just opening up. The longest I've kept it in the cooler was 5 days and it did fine. The florists call it yellow Queen Ann's lace. Depending on the size of your plants it might take a year or two to flower. From seed it takes 2-4 years to bloom. I wasn't aware the flowers were edible, I'll stick to just cutting them and harvesting the seed.

Steve, Thanks for the info! I'm going to try to get some more seeds going this year. The ability to take refrigerqation is a real plus.
