Canada's Carnivorous Plant pride! Our only pitcher plant but it widespread across every province and territory with the possible exception of the Yukon. Low-growing rosettes of green to purple leaves, with flowers held far above the plant. The flower structure can be a dead give a way to the location of a plant even when the rosettes can't be seen. Typically occurs in bogs and other wetlands but can sometimes be found on unusual soils (like some populations around the great lakes). It is also the provincial flower of Newfoundland!
Plants from this locations are widespread in cultivation as 'marl bog form'. In fact these are from the type location of var. riplicola (Boivin 1951). Since then it has been proven in many transplant experiments that the dwarfed growth is mainly caused environmentally. So plants from marl bogs or fens are not a good forms and var.riplicola is not a useful name. However I have the impression that those plants from Bruce Pensinsula do have small pitchers and flowers compared to other ssp.purpurea under identical growth conditions.
This plant has large, somewhat elongated pitchers that get quite dark red. The flower stalk gets really long, too. The petals have some orange touch which is more obvious when compared to the purple colour of other purpureas. Other plants often develop two growth points after flowering, this plants almost never does. However it is one of the first to stop pitchering only to develop another flower in late summer. Apparently the summers here last way too long.
cultivated plant This fen plant is quite different from the Bruce Peninsula 'marl bog form'. A typical veined form, comparable to other plants of bogs in Southeastern Ontario. The red band is the nectar zone that is less obvious in redder plants.
cultivated plant The pitchers of these plants from Prince Edward Island get quite large and have well developed hoods. This reminds me of some S. purpurea ssp. purpurea that grow farther south on the US Atlantic Coast.
Pitcher plants growing in Sphagnum at Alfred Bog near the boardwalk. I saw only few plants growing here. This large ombrotrophic bog used to be exploited by commercial peat mining, but most of it is now protected (more info on this place - OFNC).
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. 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). In both cases it is not possible to rule out that the plants 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.
These purpureas grow naturally at an inland lake East of Georgian Bay in the District of Muskoka. They are a bit larger than those South/SW of Georgian Bay. I grew several of those plants from seed and I think they are quite typical for ssp.purpurea. The flower petals are a bit acute at the tip, pale and greenish along the rim, similar to other purpurea from central/eastern ON that I grow.
Bonjour Jeff, no, I did not systematically look at seed and pollen. Frankly, I don't think there is too much to be learned, but I may be wrong. I also don't have a sufficiently variable set of seed and pollen from different locations for a good statistic. The pollen looks very similar. Ellison looked at Sarracenia seed inter- and infraspecifically a few years ago, but the data is just good enough to see S.rosea is different from S.purpurea. Eric
These are just snapshots showing the variability of different populations from different places in Canada. Some populations are very uniform, others surprisingly variable in form and colour. It is still very difficult to show if there are any well defined, geographically distinct taxons. Plants from the Maritimes may look different from those around the Great Lakes, but in fact many reseachers still struggle to draw a clear line between ssp.venosa and ssp.purpurea. Eric
