The paper presents UBVI CCD photometry for 2709 stars in the loose Galactic globular cluster NGC 5897. The measurements carried out in the very central regions reach below the main-sequence turn-off. Analysis of the color-magnitude diagrams show that the overall morphology of the main branches closely resembles that of the similarly low-concentration cluster NGC 288, including the presence of a clear gap along the almost identical horizontal branch and a population of blue stragglers. The BS candidates (34 plus about 10 at lower confidence) are found to be more centrally concentrated than the cluster subgiant stars of similar brightness at the 2-sigma level of confidence. Based on a wide forthcoming review of the CMDs of all the clusters containing BS, arguments are presented to suggest the detection of a very small BS progeny on the red HB extreme.
