Subject: Cold treating Sarracenia seed

My experience has been:

1. Stratification for 6 weeks in the fridge is a waste of time and
space compared to 36 hours in the freezer. Put the seed in paper
packets, immerse in a container of water and freeze, defrost, allow
packet to dry out for easy separation of the seed and sow.
Germination is excellent, fuss is minimal. Works the same for
Darlingtonia. Obtained similar results soaking the seed overnight in
10% solution of gibberelic acid instead of stratifying/freezing.

2. fresh seed germinates well without stratification (a few stragglers
appear the following spring). The context is an unheated glasshouse that
does not freeze - external temps of minimum c. -6 degrees C, max day
temps 10-15 during winter. The seedlings are well ahead of waiting for
germination the following spring.
