Heirloom
Crystal Apple Cucumber is a rare heirloom that nearly vanished from American gardens but deserves a comeback. The petite 3-inch creamy white fruits truly do resemble small apples, both in size and appearance, making them instantly recognizable among cucumber varieties. Introduced from Australia around 1930 through Arthur Yates and Co., though likely originating in China, these tender cucumbers are so delicate you can eat them skin and all. Ready to harvest in 70 to 80 days, they thrive in full sun across zones 2 through 12, giving gardeners across most of North America the chance to grow this nearly lost treasure.

The skin is so tender it requires no peeling, a rarity among cucumbers that lets you eat the fruit whole and raw straight from the vine. Bright creamy white fruits about the size of an apple give this variety its distinctive name and appearance. The flavor is genuinely sweet and mild, with a delicate texture that sets it apart from the crisp, watery cucumbers found in most grocery stores. This variety came dangerously close to extinction in America, making seed saving and cultivation an act of horticultural preservation.
These delicate cucumbers are best enjoyed fresh and raw, where their tender skin, mild sweetness, and crisp texture shine without any processing. Eat them whole straight from the vine, slice them into salads, or serve them as a crunchy snack. Their small size and apple-like appearance make them visually striking on platters or in lunchboxes. Because the skin requires no peeling and the flesh is so tender, they're particularly suited to fresh eating rather than pickling or cooking.
Sow seeds directly into the garden at a depth of 1/2 inch once soil temperatures reach 65 to 80 degrees Fahrenheit, typically after the last frost date when the soil has warmed adequately. Seeds will sprout in 5 to 14 days under ideal conditions. Plant in full sun in soil with a pH between 6.0 and 7.0.
Harvest fruits when they reach approximately 3 inches in length and have developed their characteristic bright creamy white color. Pick them when they are still tender and the skin easily yields to gentle pressure; waiting too long results in larger, tougher fruits that lose the tender texture that defines this variety. Regular harvesting encourages continued production throughout the growing season. Cut fruits from the vine using pruning shears or a sharp knife rather than pulling, which can damage the delicate vines.
As a vining cucumber, Crystal Apple benefits from training onto a support structure like a trellis or vertical stakes. Guide the main vine upward and gently tie it to your chosen support using soft string or plant clips, allowing lateral shoots to develop along the length of the vine. Prune back excessive vegetative growth that shades developing fruit, but avoid over-pruning, as some foliage is necessary to protect the delicate fruits from sunscald.

“Crystal Apple Cucumber arrived in American gardens through the Ferry Morse seed catalog in 1934, but its journey began earlier and farther away. The variety was already popular in New Zealand and Australia, where Arthur Yates and Co. introduced it around 1930. Its true origins trace back to China, though the specific cultivators and families who first developed it remain largely undocumented. Over the decades, as modern slicing cucumbers dominated both seed catalogs and kitchen gardens, Crystal Apple slipped into obscurity until heirloom seed companies like Baker Creek rescued it from near extinction. Its reappearance in contemporary gardens represents a deliberate effort to preserve agricultural biodiversity and reconnect with older, less commercialized food varieties.”
