Allium aaseae reproduces from both seed and bulb division. Seed viability from different sites is variable, as is often the case in wild pant populations. The mean viability from four sites studied by Prentice (1988) was 55%. The number of seeds per pound is estimated to be 622,000 (Prentice 1988). Seed production is also variable from year to year (Prentice 1989). The pollination biology of Allium aaseae is unknown, although it has been reported to have no specific pollinators, and flowers visited by many types of insects (Bolin and Rosentreter 1986). This species flowers early in the season and likely makes use of any insect taxa active at this time of year. Seed dispersal mechanisms are unknown, but probably at least partly relies on the dried, detached umbel being blown around (Packard 1979).
