FlytrapCare Carnivorous Plant Forums

Hey guys, I'm growing carnivorous plants from seeds and I need help. What kind of carnivorous plant do I need to stratify and what kind do not need it. I know sarracenia need stratification and nepenthes do not, can you guys get me in on the rest please. Thank you

Temperate Drosera also need cold stratification for the best germination results. Example: d.intermedia, d.filiformis, d.rotunifolia, d.linearis, d.anglica. I am sure there are several more.

Basically you just need to consider their place of origin. If it comes from a place with a distinct winter, then chances are it will need stratification. This is an adaptation to keep seeds from germinating in late fall and then freezing before they have a chance to get established. (In the case of annuals, it assures that they can mature and produce seed before the freeze comes, but I can’t think of any temperate annual carnivores right offhand.)

One seeming exception would be the warm temperate Pinguiculas; it might seem odd that they don’t need stratification while the pitcher plants that share their same regions do. The reason is mainly that they mature their seed quite quickly/early (as opposed to pitcher plants, which take an entire season), so the plants have plenty of time to get established.
