Commercial cultivars of Euphorbia pulcherrima serve as natural hosts.

[2][3] Its RNA suggests a replication mode like that of poleroviruses, whereas the coat protein sequence is closely related to that of sobemoviruses.

[4] Viruses in Polemovirus are non-enveloped, with icosahedral geometries, and T=3 symmetry.

The virus exits the host cell by tubule-guided viral movement.
