sarracenia purpurea f. pallidiflora

Sarracenia purpurea ssp. venosa var. venosa f. pallidiflora (anthocyanin-free venosa)

USA / man-made

First described
2013
Type
extremely rare AF form with active rot resistance breeding project

The only known anthocyanin-free form of S. purpurea ssp. venosa. Stated as man-made; possibly originating from a single original mutant + selfed-seed propagation. Mike's original strain was extremely rot-prone and lost over time in the US, but Mike's multi-generation rot-resistance breeding project (2013-2025) has finally produced a vigorous, rot-free AF venosa line scheduled for distribution.

History

  • 2013-08-04 — Mike's introduction. Folded-hood phenotype noted.
  • 2013-08-07 — Stew McPherson's f. pallidiflora naming surfaced by hcarlton.
  • Multi-generation 2013-2024 — Mike crosses original AF with rot-resistant venosa from his collection. NOT a selfed approach.
  • 2025-04-03 — first vigorous AF F-generation announced.
  • 2025-11-14 — culled survivors all rot-free; distribution planned.

Standout traits

  • Anthocyanin-free pure yellow expression
  • Folded-hood (some clones) — montana-like
  • Original line rot-prone; Mike's 2025 line rot-resistant
  • Genetic basis: one-locus AF mutation (per hcarlton)

Standout traits

  • Anthocyanin-free — the only known AF form of ssp. venosa
  • Bright yellow under optimal conditions, sometimes with a slight white tinge from sun-bleaching
  • Folded hood (some clones) — montana-like morphology
  • Extremely rot-prone — Mike's biggest cultivation failure: 'I lost them ALL over time' (post #7, 2025). Most US growers face the same outcome.
  • Original clones still going in Europe (Mike, post #7, 2025)
  • Selfed-line origin hypothesis explains the rot susceptibility — homozygosity at multiple disease-resistance loci

Cultivation

Original AF venosa strain: extremely rot-prone, virtually uncultivable long-term in the US.

Mike's 2025 rot-resistance-bred line: super vigorous, easy to grow, no rot issues so far. Distribution pending.

Naming

"f. pallidiflora" — Stew McPherson's formal varietal naming in the new Savage Garden (referenced by hcarlton, post #2, 2013). Mike prefers the informal "S. purpurea venosa AF."
