🌍 Origin Region
Central and South America; cultivated globally in tropical and subtropical regions
📅 Days to Maturity
Takes approximately 360 to 730 days (1 to 2 years) from seed to first flowering and fruiting under optimal conditions, often faster from cuttings.
🌡️ Hardiness Zones
Thrives in USDA Hardiness Zones 10 through 11; minimum temperature tolerance around 32°F (0°C); grown as a perennial in tropical climates or potted indoor/greenhouse plant in cooler zones.
About This Seed
Seeds are extremely tiny (approx 1-2 mm), tear-drop shaped, glossy dark brown to black with a smooth hard seed coat, shown here actively germinating on a paper towel with emerging white radicles. The resulting plant is a climbing, epiphytic cactus with segmented, triangular green stems and large, stunning nocturnal white flowers, producing vibrant pink or red edible fruits with sweet white flesh studded with tiny black seeds.
Growing Information
Growing Season
Spring and Summer; start indoors or direct sow in frost-free climates; frost-intolerant
Germination
Germinates in 7 to 14 days at an optimal soil temperature of 70°F to 85°F (21°C to 29°C); high germination rate; requires surface sowing or very light covering as they need light to germinate; no pre-treatment strictly required.
Planting Instructions
Surface sow or press lightly into moist, well-draining soil mix (cactus mix ideal); keep consistently moist until germination; ideal soil pH between 6.0 and 7.0; indoor starting or greenhouse environment recommended initially.
Sunlight & Water Needs
Requires full sun to partial shade (6 to 8 hours of sunlight daily); moderate water needs during the growing season, allowing soil to dry slightly between waterings; highly drought tolerant once established, sensitive to overwatering.
Companion Plants
Grows well with other tropical succulents and nitrogen-fixing plants; avoid planting with high-moisture lovers that compete for root space.
Special Characteristics
Drought tolerant, heat loving, produces striking nocturnal fragrant flowers pollinated by bats and moths, highly ornamental edible fruit, highly attractive to pollinators.
