San Ignacio dragonfruit is a vigorous climbing cactus from Nicaragua that produces enormous, strikingly beautiful fruits weighing around 2 pounds each. The plant's three-sided stems are bright green with small clusters of spines, and it flowers spectacularly with large blooms featuring white inner petals and bold yellow-red outer petals that open at night. What truly sets this variety apart commercially is the sheer size and sweetness of its fruit, which can reach up to 19 brix when fully ripened on the vine, making it as rewarding to eat fresh or juice as it is to grow.

San Ignacio produces some of the largest dragonfruit on record, with individual specimens regularly hitting 2 pounds and developing deep red flesh studded with edible black seeds. The plant thrives in full sun and handles drought exceptionally well thanks to its waxy stem coating, which develops as it matures and protects it through both heat and frost stress. Night-blooming flowers with unusual yellow-red coloration are pollinated by night-flying insects, but the variety remains self-sterile, requiring cross-pollination with white, purple, or pink-fleshed dragonfruit varieties to set fruit.
San Ignacio dragonfruit is enjoyed fresh as a ripe fruit, where its sweet red flesh and edible seeds provide a refreshing tropical experience. The catalog recommends eating half the fruit fresh to appreciate the delicate flavor while juicing the other half, a practice that takes advantage of the fruit's generous size and juice content. The high brix levels (15 to 19) make it particularly suited to juice, smoothies, and other preparations where the natural sweetness can shine.

San Ignacio dragonfruit is ready to harvest when the fruit reaches full size, typically around 2 pounds, and develops its characteristic deep red color. The longer the fruit remains on the vine after reaching mature size, the sweeter it becomes, with brix levels ranging from 15 to 19 depending on ripeness and sun exposure. Harvest by cutting the fruit cleanly from the vine rather than pulling, taking care not to damage the small green fins that cover the surface. The fruit's heavy weight will be apparent when handling, so support the fruit with one hand while cutting the stem with the other.
San Ignacio is a climbing species with strong, bright green three-sided stems that will sprawl extensively without support. Guide the plant along a sturdy trellis or support structure to manage its growth and encourage upright climbing. Minimal pruning is needed beyond training and directing growth upward, as the plant's natural vigor supports itself well once established on a framework.

“San Ignacio represents a fascinating case of commercial dragonfruit cultivation in Central America, specifically Nicaragua, where this variety has become economically significant. The plant's genetic identity reveals the complexity of dragonfruit taxonomy: while botanically classified as Hylocereus costaricensis based on its growth, flower, and fruit morphology, DNA analysis has linked it to the Armando dragonfruit variety, suggesting a shared heritage within the Hylocereus genus. This genetic relationship and the variety's strong performance in Nicaraguan growing conditions have made it a standard in regional commercial cultivation.”
