Cereus Forbesii Seeds — The Fast-Growing Torch Cactus That Blooms, Fruits & Grafts

Cereus Forbesii is the versatile powerhouse of the columnar cactus world: a fast-growing South American torch cactus producing architectural columns, spectacular fragrant night-blooming flowers, edible fruit, AND serving as one of the most popular grafting stocks for rare cacti. Also known as Forbes' Torch Cactus, this striking columnar species originates in arid regions of northwestern Argentina and Bolivia, developing slender blue-green ribbed stems reaching 10-20 feet tall. The vertical ribs create distinctive architectural texture, adorned with clusters of dark spines. What makes Cereus Forbesii special is the combined package: mature plants produce enormous white slightly fragrant flowers blooming exclusively at night, opening at dusk and lasting through darkness before setting fruit. Subsequent fruits are edible pitaya-type... large, hairless, containing crunchy edible seeds with mildly sweet flesh reminiscent of dragon fruit. Beyond ornamental and food value, Cereus Forbesii is prized as premium grafting stock... its vigorous growth and adaptable roots make it ideal host for grafting rare, slow-growing cacti. Hardy to Zone 9, easy from seed, drought-tolerant, remarkably productive.
