Last year I purchased two packets of Darlingtonia seeds from the carnivorous plant society seed bank. One packet was labeled Darlingtonia from Siskiyous Co and one was from Del Norte Co. Both seed packets were stratified the same period, planted in the same medium type, and also grown in the same conditions in a crawlspace under artificial lighting.
The plants grew at significantly different rates as can be seen in the photos below. After watching the video Serpants of the Siskisyous by Sarracenia Northwest I figured that the two plants live in different environments. What I can't seem to figure out is what environment the Darlingtonia seeds from Del Norte Co need for a proper growing climate. These plants appear to be way behind in growth compared to the Siskisyous seeds. Are the Siskisyous seeds even Darlingtonia. They seem to more closely resemble Sarracenia purpurea to me but maybe this is do to the plants still being young.
Can someone please help me? Up to this point they have spent most of the time in a damp crawlspace where the temperature ranges from low 60's in the winter to about 67F in the summer. The phot period has been set for 16 hours. The Del Norte seeds have spent a small amount of time outside hoping the warming temps may help them out but have not seen much change. Im out of ideas. Any help or suggestions would be greatly appreciated. Oh and I am located in Central Nebraska. Maybe they just need more time outdoors here.
Yeah, the plants on the right are definitely S. purpurea, not Darlingtonia. Also, the soil for the cobra lilies looks a little dense for their liking. They need rather well aerated soil (long fiber sphagnum and perlite or pumice works well), and cool water.
I may have been keeping them a bit wetter than needed but I have never grown these before and don't yet have a feel for them. They seem to be much slower growing than say purple pitcher plants and others is this normal?
