More than 50 exoplanets have been detected around giant stars, revealing different properties when compared to planets orbiting solar-type stars. In particular, they are super Jupiters and are not found in orbits interior to ~0.5 AU. In 2009 we started a RV search for planets around giant stars, aimed at studying the population of close-in planets and how their orbital and physical properties are influenced by the host star evolution. In this talk I will present the results from our project, highlighted by the detection of several giant planets and a highly eccentric brown dwarf in the ""desert"". I will also review the peculiar properties of planets orbiting evolved stars, and I will discuss about different scenarios that might explain these observational results.
