K-3, "Kathy" is one of my favorites. Creamy texture, top-tier excellent flavor, skin covered with resin sparkles that show proper maturity for picking. In 2015, I picked from over a dozen 'Kathy' trees at different Zill-owned locations, from most of early season, all through mid-season, and partly into late season. (This length of season did not occur on an individual tree--- so differences of soil and sun exposure and irrigation systems apparently contributed.)
