Color images and spectra of the three host galaxies of our long-rising SNe II from PTF. The hosts of PTF09gpn and PTF12kso are particularly faint and metal poor. In the color images the position of the SN is marked by a black “+”, and the scale as well as the orientation are reported. The color image of the host of PTF09gpn was obtained by combining three images in gri filters that we obtained with P60. The images of the other hosts are from SDSS. In the host-galaxy spectra, shown in the rest frame, we identified the most prominent emission lines. Some of them were used to estimate the metallicity.
