N2 - Let k0 be a field of characteristic 0 with algebraic closure k. Let G be a connected reductive k-group, and let Y be a spherical variety over k (a spherical homogeneous space or a spherical embedding). Let G0 be a k0-model (k0-form) of G. We give necessary and sufficient conditions for the existence of a G0-equivariant k0-model of Y.
