What happens when different species hybridize?

Together, the common (Asclepias syriaca) and showy (Asclepias speciosa) milkweeds span most of the continental United States. These species come together and form hybrids in the central US. 

We are interested in understanding the genomic and metabolic consequences of hybridization between the common and showy milkweed. We are studying the species differences through common gardens, greenhouse, and lab experiments.
