  We study the time evolution of spherical, excited -- with $n$ radial nodes --
scalar boson stars in General Relativity minimally coupled to a complex massive
scalar field with quartic self-interactions. We report that these stars, with
up to $n=10$, can be made dynamically stable, up to timescales of
$t\sim\frac{10^{4}}{c\mu}$, where $\mu$ is the inverse Compton wavelength of
the scalar particle, for sufficiently large values of the self-interactions
coupling constant $\lambda$, which depend on $n$. We observe that the
compactness of these solutions is rather insensitive to $n$, for large
$\lambda$ and fixed frequency. Generically, along the branches where stability
was studied, these excited boson stars are not compact enough to allow for
innermost stable circular orbits or light rings. Finally, we discuss the
angular velocity of particles along timelike circular orbits, suggesting an
application, for solutions in the Newtonian limit, to galactic rotation curves.
