Yes, Christine, it's the Mammoth Dill. I'm 5'2" and the tops of the plant were taller than me! I want to save the seeds so I can plant more this fall and then next year. I'd also like to trade some away or just give the seeds away. I've so enjoyed having it in my garden and have enjoyed the smell when I'm working in the garden.
I'll head out to the garden this evening with my paper bag and start collecting the seeds!
