Trichocereus hybrid 'red'

This unnamed Trichocereus hybrid I bought some tome ago from the garden store, with grafting in mind. Something got on the way and that grafting project got postponed for a while, and in the meantime the plant bloomed. After seen the flowers it was spared from becoming a grafting stock, and 'lives happily ever since'. It usually produces one or two flashes of that beautiful red flowers per season, and I use it to make seeds crossing with other Echinopsis hybrids I have.
