  We study equivariant real structures on spherical varieties. We call such a
structure canonical if it is equivariant with respect to the involution
defining the split real form of the acting reductive group G. We prove the
existence and uniqueness of a canonical structure for homogeneous spherical
varieties G/H with H self-normalizing and for their wonderful embeddings. For a
strict wonderful variety we give an estimate of the number of real form orbits
on the set of real points.
