White Wonder is a pre-1890 heirloom cucumber from upstate New York. Sow 1/2-1 inch deep, thin to 36-48 inches apart, and sprouts come in 4-10 days.
Black-spined fruits grow 6-9 inches long, ivory white when young and cream at full maturity. Plant outside after frost in fertile soil with compost, keep well watered, and pick daily to keep vines producing.
