I rather hoped that this 'growing from seed' idea was the norm among
nurseries! (Unless of course you can get quicker results from tissue
culture).
I assumed that the fragment of Darlingtonia I bought at a garden
centre some years ago was tissue cultured, but now I've seen
seedlings, it was indistinguishable from a bunch or seedlings a
year or so old.
I find that seed collected fresh from the plant and sown immediately
germinates freely and quickly. No cold treatment seems necessary for
fresh seed - I did keep a pot of seeds outside over Winter in the
U.K. but that just delayed germination until spring, whereas the ones
inside germinated within a few weeks. Indeed I would say that it
takes about three years to get anything that starts to look like
a Darlingtonia - the juvenile leaves are still pitchers, but they
are different shape - not really any 'hood' and only one 'tongue'/
'fang' or whatever you call those bits. I'm used to Cacti and
Succulents so three years to grow a plant is common!
I've never got commercial seed of Darlingtonia to germinate at all,
so maybe the freshness is important.
