Plants grown from seed. They are veined when growing in semi-shade and they get very red in full sun growing on peat.
Seed from this location was collected and circulated widely in the 90's. Unfortunately they did not germinate for me. The plants shown are from seed that I received (years later) from a grower in England who self-pollinated his plant. There is at least one nursery in BC that sells artificially propagated plants from this location. Another plant with the same location label made it into US collections on the West Coast. The latter is surprisingly a veinless plant. Veinless plants are very unusual and have not been reported from many places. They are found in good numbers only in a few bogs, mainly in Ontario (see Mazur(2005), CPN vol.34). It is not possible to rule out that some of the plants may have been unintentionally mislabeled.
So here are two links to see what their northern habitat (I think you can even see some pitchers and flower scapes peeking out of the sphagnum mat of this bog) and what the plants look like. The pitcher plant habitat near Ft.Nelson is one of the westernmost natural locations of S.purpurea. It is also one of the northernmost, however there are a few more locations farther North (up to circa 62°N) in the Northwest Territories.
