Cluster of Apex Plumcots
This variety of plumcots shows a pretty even balance of the characteristics of the plum and apricot ancestors. The fruit is very large for an early bearer, being from 5 1/2 inches to 6 inches in circumference. The flesh is honey-yellow, firm, rich, aromatic, resembling that of the apricot, and sweet and delicious to the taste. The Apex is the only plumcot yet introduced which has promise of becoming a standard market variety, though there are others equal or superior to it in the proving orchard.
