Fred, do you have location information on your other clones? I would guess that your Siuslaw National Forest clone is possibly from the coastal population near Florence. If Darlingtonia flowering is triggered by daylength or temperature clues, knowing the location of your various clones might help answer why. An interesting problem.
The indoor/outdoor flowering timeing suggests a temperature clue, unless you use artificial lights for the inside plants.
I'm afraid that apart from the Siuslaw clone I have no idea of location.
The inside colonies and one outside are the same and I've had this clone since the early 1980s, 1983 I believe. Plants didn't come with location details that often then, at least not in my direction.
One other colony I just snapped up cheaply on ebay last year.
As for the flowering, I have the 3 different clones outside and Siuslaw is behind the other 2. My old clone is the furthest on. So if Siuslaw is coastal and used to higher temps and the other 2 are from colder climes it could explain it.
Anyone else growing Siuslaw and finding a difference?
The colonies I have outside are not yet flowering. The furthest from opening flower/s is from Siuslaw National Forest. Any opinions as to why?
I thought I'd better update. The colonies are doing extremely well, pitcher production is good. Both my own clone and the "EBay" clone flowered well outside in their bird/squirrelproof cages and have put on a lot of good growth The Siuslaw clone didn't flower, the whole plant looks like it's going backwards. The flower stem died back and there is as yet no new growth, very odd for this time of year.
I have therefore had to take this plant into the greenhouse and hope the extra heat will pull it through, I will continue to post on its performance.
The colonies are now well into pitcher production. Junior is now taller than Mother.

The Siuslaw clone I took into the greenhouse to give more protection and the extra heat is now shooting in two points. One close to the main plant and another which must be from a runner. It looks like this one prefers the warmer conditions, that probably means that MrsG will lose even more room in the top greenhouse .
I'm so proud and envious of your ability to grow Darlingtonia. We received a donation of coastal and mountain Darlingtonia from Sarracenia Northwest about two months ago. We set them up on the dripping wet concrete floor of the greenhouse (soil temp of 69F - upper limit for Darlingtonia in my book). Greenhouse has evaporative cooler and shade cloth. Well, forget the mountain clones. They briefly started to grow, stopped, and blackened. The coastal plants produced pitchers but they got attacked by fungus and all the plants are now dead.
I really wonder what the difference is in cultivation between England and eastern U.S. I'm very suspicious of an indigenous pathogen but who knows.
