This info was found at Davewilson.com, who seems to be the main grower: "The first NectaplumŽ from Zaiger Hybrids. Spice Zee packs a pile of amazing fruit into an attractive tree for the home gardener. It is slightly acidic and loaded with sugar giving it a spicy sweet flavor. One can detect both Plum and Nectarine traits with ease. Along with great flavor, Spice Zee is a beautiful ornamental tree with a tremendous spring bloom followed by dark red leaf in the spring that matures to a rich green-red in late summer. This variety is self-fruitful and very productive."
