Hello, my name is Nina Denne and I am currently a freshman at Carleton College. I will be working as an extern at the Chicago Botanic Garden for the next 3 weeks, specifically looking at the relationship between reproductive fitness of Echinacea and the diversity of the surrounding habitat. For now, I’m mostly cleaning Echinacea heads and then I will be counting the achenes and X-raying achenes to determine whether they are viable. I’m very excited to be back at the Botanic Garden after having conducted a germination experiment with two species of Echinacea in high school.
