Table 1. Characteristics of the four Asclepias species used in monarch oviposition choice experiments.

Species	Clade	Habitat	Clonal potential	Clonality
A. syriaca	Temperate North American	North eastern open fields	31	Clonal
A. tuberosa	Temperate North American	Dry fields and open woodlands	0.3	Non-clonal
A. verticillata	Incarnatae	Midwestern prairie	1.4	Clonal
A. incarnata	Incarnatae	Eastern wetlands	0.4	Non-clonal

Note:

Shown are each species’ clade (Fishbein et al., 2011), natural habitats (Woodson, 1954), and clonal potential defined as root buds per plant after ~45 days of growth (Pellissier et al., 2016).
