Identifying Common Nepenthes Hybrids: deRoose Varieties and Rebecca Soper

A grower purchased two unidentified Nepenthes from Home Depot, labeled only as "Monkey Cups" and "Pitcher Plant." After seven months of successful growth, she sought identification to expand her collection knowledgeably. Photos showed two distinct plants: one with numerous variable-sized pitchers up to 7 inches and slender leaves to 9 inches; the other with fewer, larger pitchers to 10 inches and broader leaves to 14 inches.

Jeff Dallas identified the first as "deRoose's alata," a vigorous hybrid: N. alata × (N. alata × N. ventricosa), mass-produced by deRoose Plants in Florida and the Netherlands. The second is N. × 'Miranda' (N. maxima × N. northiana), another deRoose hybrid known for large 12-inch pitchers in good conditions.

A follow-up query included a third plant: a compact specimen with 3–4 inch deep purple pitchers, mint-green interiors, textured wings, and slender purple-tinged leaves to 8 inches. Dallas identified this as 'Rebecca Soper' (N. gracillima × N. ventricosa), often sold under the trade name "Alata Lantern" despite lacking N. alata parentage. He notes it's reported as easy and vigorous.

Dallas emphasizes that precise identification is only feasible for common, mass-produced clones. With thousands of hybrids exhibiting subtle variations, most unnamed plants remain "Poi-Dogs"—beautiful but of unknown parentage. He recommends the Carnivorous Plant Photofinder (run by Bob Ziemer of ICPS) as a valuable reference for baseline comparisons.

In a final exchange, the grower notes similarities between Nepenthes and Sarracenia hybrid complexity. Dallas confirms natural Nepenthes hybrids occur in tropical regions like Hawaii, but home hybridization is impractical: plants are dioecious (separate male/female), flowers are malodorous (chemical/bleach scent), and hand-pollination is difficult. Sarracenia are far easier to cross.
