Slicing Cucumber
White Wonder Cucumber is a striking heirloom variety that defies expectations with its creamy ivory skin and abundant yields across hardiness zones 2, 13. Ready to harvest in 65 days (though some sources indicate 35, 60 days), these vigorous vining plants produce crisp, plump fruits reaching 7, 9 inches long and up to 3 inches wide. Grown in full sun on short vines, they thrive even in summer heat when other cucumbers falter, making them both a stunning garden spectacle and a reliable producer.

The sheer visual drama of ivory cucumbers ripening against dark green foliage sets White Wonder apart from conventional green varieties. These fruits remain wonderfully crisp and are remarkably productive, even during intense summer temperatures when heat stress typically stalls other cucumber types. The combination of unusual color, exceptional flavor, and heat tolerance makes this variety a true conversation starter that delivers genuine harvests, not just ornamental appeal.
Fresh eating in salads is where White Wonder truly shines, the ivory skin and crisp flesh providing both visual interest and satisfying crunch. These cucumbers can also be pickled when harvested at smaller sizes, their pale color creating an elegant appearance in jars. The heat tolerance makes them especially valuable for summer harvests when peak-season freshness matters most.
Start seeds indoors five to six weeks before your last expected frost date in seed starting mix. Sow seeds at a depth of 1/4 inch, keeping soil warm and moist with strong light available. Once seedlings are large enough to handle, transplant them 2 inches apart into deeper containers to give roots growing room, then space them 10 inches apart when they reach 2, 3 inches tall, hardening them off before moving outdoors.
Transplant seedlings outdoors after all danger of frost has passed and soil has warmed. Space plants 18 inches apart with 6 inches between rows. Harden off seedlings gradually by exposing them to outdoor conditions for increasing periods before final planting.
Direct sow seeds outdoors when danger of frost is past and soil has warmed. Plant several seeds per hill, then thin the weakest plants to achieve proper spacing of 18 inches between established plants.
Harvest White Wonder cucumbers when they reach 7, 9 inches long, checking plants every two to three days once flowering begins. The pale ivory skin should be firm to gentle pressure, and fruits are ready at full size for fresh eating or slightly smaller if pickling. Clip fruits from the vine with scissors or pruners rather than pulling, which can damage vines and reduce subsequent yields.
White Wonder cucumber is a vigorous vining plant that benefits from light pruning to direct growth and improve air circulation. Remove any diseased or damaged foliage as it appears. If trellising, guide main vines up the support and remove competing lateral shoots to focus energy on fruit production, though the variety is productive enough that minimal pruning is necessary for good yields.

“White Wonder is an heirloom cucumber variety that has been preserved and passed down through generations of seed savers. Its distinctive pale skin and vigorous growth habit earned it a place in home gardens and seed catalogs as a non-GMO offering, valued by gardeners seeking both novelty and proven reliability. The variety represents the kind of genetic diversity within cucumbers that industrial agriculture largely abandoned in favor of uniform green types.”
