The love of winter – Pipsissewa

Chimaphila  from Greek: cheimon – winter, philein – to love

Pipsissewa from Cree language, meaning ‘it breaks into small pieces’

As we start looking towards the New Year, another thing becomes more obvious for those living in the northern hemisphere: winter has settled in! You absolutely have to love it; or you’ll be miserably dragging over 3+ months of hating it. Choose for yourself… Myself, I can’t wait to start new seeds experiments and to write more about the plants I love. Here’s the first one to put you in the mood of winter love ;)

Chimaphila umbellata (Pipsissewa, Prince’s pine) is another species about which I developed a mild obsession to propagate from seeds. It has showy, leathery, evergreen foliage, equally interesting pink, fragrant flowers and it grows in shady places (it has a taste for a slightly acidic soils). It would look great at the edge of the woodland garden or on the shaded side of a rockery. The dry capsules are also very ornamental and last into the next season; they contain lots of tiny, dust-like seeds (much like the Cypripediums) which are released easily when mature. The best time to try to collect them is in late fall.

The species is morphologically variable across its native range. Five or six subspecies have been recognized in the literature, depending on what source you look at; for example, the one from Ontario would be C. umbellata subsp. cisatlantica – it never gets easy…

Only the difficult propagation made it virtually non-existent in cultivation. According to some sources, Pipsissewa is a partial myco-heterotrophic plant, which means that it obtains a portion of its nutrients from parasitizing fungi that are part of mycorrhizal associations of other plants. It also forms its own mycorrhizal symbiosis with fungi. Kind of complicated…

Reportedly, it can be propagated from cuttings and from rhizome fragments but not very successfully (I presume, otherwise we would have seen it in cultivation). I don’t have the conditions to try rooting cuttings and don’t feel like uprooting plants to take rhizomes, so I’ll stick with seed germination trial-outs. Others have tried with some success stratification of fresh seeds in a mix inoculated with local soil, and the fine size of the seeds suggests that it might be a light sensitive germinator. We’ll see how it goes…

Pipsissewa was and still is valued for its medicinal properties. Native Americans used it in their traditional medicine mainly for treating rheumatism, as well as for kidney, liver disorders (leaves), and other ailments. Scientific research has confirmed its pharmacological qualities a long time ago, and the modern therapeutic use of C. umbellata reflects the traditional indications. In short, it can be used like Arctostaphyllos uva-ursi, but its active components are more potent.

Today it is utilized in small scale modern herbal medicine, but has become the component of a proprietary formula – Eviprostat® largely used in Japan and Europe for the treatment of benign enlargement of the prostate.

If this is good news, the bad is that Chimaphila has been classified as a slow-growing perennial, sensitive to harvesting pressures, ecological disturbances, and foot traffic; also various reports have emphasized that it regenerates too slowly for regular commercial harvesting.

    I love pipsissewa. It grows in profusion in the Pinhey Forest near my home in Nepean/Ottawa. There are hundreds of plants. Fortunately it grows in the area where an ancient sand dune is being uncovered by volunteers and I have been able to dig some plants as a part of the uncovering. They are growing in what I think is similar soil, under a white pine close to my yellow trilliums. This is the second year for a few and the first for others.

    While I am commenting I note that you have often written about giant lady slipper orchids. You never mention the Purdon fen at Macdonald’s Corners in Eastern Ontario where they have been carefully nurtured for many years and are open to visitors who can pass among them on wooden walkways that BTW will also support wheelchairs. Other plants are there as well including pitcher plants.

      Thank you for sharing the love of winter! I never saw Chimaphila in such large numbers, but that’s hopeful such places exists. Also, thanks for the info on the Purdon fen – I didn’t know
      about it. So many places to visit and so little time.

    I have never seen Pipsissiwa in the woods around here but we do see a relative of theirs (I think) sometimes… the pinedrops…which are also very interesting.

      Glad to hear from you ;) We have another beautiful Indian pipe here: Monotropa uniflora, I have never seen your pine drops – so many species!
      Unfortunately they are entirely parasitic plants.
