Experimental seed addition in a small field study resulted in no seedling establishment after three years (Brudvig et al. 2011); however, Zizia's preferred habitat is prairie (Eilers and Roosa 1994), and likely there was too little light in this forested study. Cullina (2000) reports that seeded into pots, seedlings came up well, and flowered the following summer.

Has low seed output and limited vegetative spread (Barkely 1986, Gleason and Cronquist 1991).
