Zeta Virginis is just north of Spica, about a third of the distance from Spica to Arcturus: binoculars.

Between zeta Virginis and gamma Virginis (Porrima) is a delightful binary, Struve 1719: two eighth-magnitude stars which, combined, shine with a visual magnitude of 7.0.
The fixed companion is 7.5" from the primary with a position angle of 1 (due north from the primary). The binary is situated almost exactly in the middle of a triangle formed by gamma, zeta, and delta Virginis: binoculars.
