Origin: as chance seedling grafted to Pioneer in 1963 in Baldwin County, Ala., in orchard of L.V. Underwood. Scion died and stock grew to "surprise" the orchardist and become the Surprize tree. Discovered in 1968. Seedling grew from unknown seedstock (Success suspected based on nut shape; consistent with isozyme genotypes). Tested by Gulf Coast Substation, Fairhope, Ala., from 1983. Introd. commercially by Dellwood Nursery, Foley, Ala., about 1983. Nut: ovate elliptic, with acute apex and rounded base; flattened in cross section; 31 nuts/lb, 51 % kernel; kernels with wide dorsal grooves, concave ventral surface. Initiates growth late, mid-April in Fairhope. Protandrous. Moderate precocity, with consistent production on mature trees. Ripens mid-to late-season, about 6 days after Stuart. Good disease resistance in south Alabama. Recommended for trial planting in Alabama. Tree: Fruit:
