Single delights – Moneses uniflora

,

“Ever tried. Ever failed. No matter. Try again. Fail again. Fail better.”
Some may argue that this famous Samuel Beckett’s quote is not an inspiration for trying and grow very difficult species, but I differ. With every failure we will, at least, learn something a bit more about them.

This long overdue post is about mycorrhizal species, included in the Orchids & other mycorrhizals shop category and especially about Moneses uniflora – the single delight. It always keeps one to want more ;)

Some people are more adventurous than others when it comes to growing from seeds – this is the reason I collect and offer, when possible, a few almost impossible to germinate/grow species. The cost of seeds is really insignificant; it’s all about the quest and desire to go beyond what’s easy.
In other words, for those loving to grow plants from seeds – it’s also fun!

Moneses uniflora is a little, evergreen species growing in shady, cool places, and not often encountered. Managing to grow it in the garden, it would be nothing short of a miracle but nothing is impossible.
Like all species from the above mentioned category, it requires a specific mycorrhizal fungus at least for germination and maybe even later for growth.

This one single delight was spotted growing on top of decaying, exposed roots covered in moss in the Lizard Mts., BC. In my opinion, this may offer a hint about the way one could go about when trying to germinate it.

This is my advice for sowing Moneses uniflora (Pyrola and Chimaphila as well):

Collect a piece of decomposed wood together with some moss from the woods; place them in the garden, half buried in the ground to stay moist in a shady location; sprinkle the very fine seeds on top and water well to washed them in the moss. Keep the spot moist at all the time and….fingers crossed.

Few years ago I tried sowing in the same way Pyrola elliptica (same category) with the decomposed wood/moss placed in a pot. I noticed tiny, green sprouts in late spring but then it slipped my attention and got dry at some point, so I cannot draw a real conclusion; must repeat it in the ground in a good shaded place where I water regularly (under a Chinese Epimedium, for example).

Try again :)

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.
