The Epiphyllum oxypetalum, widely recognized as the Queen of the Night cactus, is celebrated for its fragrant, nocturnal blooms. This captivating plant also produces a distinctive fruit, adding to its intrigue.
Characteristics of the Epiphyllum Fruit
The fruit is oblong and angled, resembling a small dragon fruit. It measures up to 6 inches long and 3 inches wide. Its exterior skin is a vibrant purplish-red when ripe.
The fruit’s texture is smooth, contrasting with the soft, white inner flesh. This pulp contains small, black seeds, similar to those found in other cactus fruits.
Edibility and Flavor Profile
The fruit is edible and offers a refreshing flavor. It tastes subtly sweet with a tangy note, often compared to passionfruit or a milder version of dragon fruit. Its flavor can vary depending on the specific cultivar and ripeness.
The fruit can be consumed raw by peeling off the skin and eating the pulp with its edible seeds. It’s enjoyed fresh or incorporated into desserts and beverages. While not extensively studied for its nutritional content, the leaves of the Epiphyllum oxypetalum contain proteins, fatty acids, and vitamins.
From Flower to Fruit
The Queen of the Night’s ephemeral blooms are nocturnal, opening for a single night. Successful fruit development hinges on pollination, primarily by bats and moths in its native habitat.
For fruit to set, pollen must be transferred from the stamens to the stigma, ideally from a different clone of the plant, as Epiphyllum oxypetalum is often self-sterile. After pollination, the bloom drops off, and the ovule swells, initiating fruit formation. This development can take several months, from two to four months, or up to a year to ripen. Adequate light and consistent moisture encourage fruit set and development.
Harvesting and Seed Collection
Harvesting the Epiphyllum fruit at the right time ensures optimal flavor. Indicators of ripeness include a full color change to a deep purplish-red and a slight softening when gently squeezed. A ripe fruit may also detach easily from the plant.
To collect seeds, cut open the ripe fruit and scoop out the pulp containing seeds. Soak the pulp and seeds in water to separate them from the sticky flesh. Viable seeds typically sink, while non-viable ones may float and should be discarded. After separation, the seeds are thoroughly cleaned and air dried before storage or planting.
