Huckleberry
The symbolism associated with the huckleberry is faith and simple pleasures. The tiny size of huckleberries led to their frequent use as a way of referring to something small, often in an affectionate way. The phrase "a huckleberry over my persimmon" was used to mean a bit beyond my abilities. I'll be your huckleberry is a way of saying that one is just the right person for a given job.
