AbstractExamines self-compatibility and hybridization in the genus Asclepias. Asclepias perennis and verticillata are self-incompatible, while A. incarnata is self-compatible. The study also found that A. perennis is interfertile (can hybridize) with A. texana but not with A. curassavica or A. incarnata. The results of this study may help inform safe planting distances when growing different species of Asclepias in a production setting.
