We investigate ${ ho}$ Pup using the high resolution spectral observations taken from the VLT archive and observations at a 1.8m-Korean telescope with BOES spectrograph. The atmospheric parameters are determined using the iron-line abundance analysis. We derive an effective temperature value of $T_{eff}=6890{pm}250K$, surface gravity of log g=$3.28{pm}0.3$ dex, microturbulent velocity of ${upsilon}_{micro}=4.1{pm}0.4km;s^{-1}$, and the iron abundance of log N=$7.82{pm}0.15$. The projected rotational velocity of the star is close to ${upsilon}$ sin i=3.5km $s^{-1}$. Asymmetric line profiles in the observed spectra and variation of this asymmetry with time show that both strong radial pulsation and weak non-radial pulsations are present in ${ ho}$ Pup.
