I bought Raspberry Kiss at Lowe's/HD abt 3 yrs ago; it's planted on a relatively remote part of the property, so has received minimal care. Beyond the usually cited specs, however, it has grown overtop a 7 foot high trellis and has spread laterally ~15 feet. The thorns are vicious but the reward is an outrageous display, year-round, of blossoms, regardless of watering or fertilizer. I am located on the Kona coast of the Big Island of Hawai'i. Will post pic when next i'm near the plant.
