Tag Archive for: Large-flowered Trillium Ontario

The time has come to admire again the Large white-flowered Trillium in all its forms and also few other woodland companions.

Although Trillium grandiflorum takes center stage at this time, it doesn’t grow by itself and I will show just a few species that were growing beside it in one particular area: Caulophyllum, Podophyllum peltatum (May apple), Maianthemum racemosum (False Solomon’s Seal), Uvularia grandiflora, Asarum canadense, Viola rostrata, Viola sororia. Others not shown here which associate in the wild/woodland gardens: Actaea species, Polygonatum pubescens, Thalictrum dioicum, Hepatica americana/acutiloba, Sanguinaria, Arisaema triphyllum, Viola pubescens and of course Trillium erectum.
Seeds of all are usually offered in the Seeds Shop by fall.

 

(DOD meaning: Dead on delivery)

I don’t know precisely if the DOD term was coined by the renowned Prof. Norman Deno but surely he reminded me of it while reading a delightful Bulletin of the American Rock Garden Society from 1991. DOD refers to the fact that seeds that require to be kept moist after collecting, when stored and/or delivered otherwise (by Seed companies or in Seed exchanges), are actually dead and there is little to expect of them in terms of germination. In his article named – Fatal Treatments of Seed he elaborates on how to kill seeds of 12 species by practicing wrong techniques of storing and/or germinating. For Trillium albidum, Fatal means: dry storage.

Same goes for many other Trillium species, and among them, Trillium grandiflorum. After collecting (see how the fruit looks when it’s ready), such seeds should be either sown right away or stored moist. When kept at room temperature, some seeds will emerge radicles by fall. The others, like in other hypogeal germinators, will grow a radicle/baby rhizome or tuber in the coming season, and then send up the first leaf only after another cold cycle (that means in their second year).

These are a few Trillium grandiflorum seeds with emerged radicles that I found last week, during my routine check of the moist stored seeds. A few more pots were added to my collection and I am looking forward to see these little Trilliums sending up their first leaf next year! The other seeds are still in moist storage, awaiting…

Providing moist-packed seeds it is a lot of work but BotanyCa will not be responsible of any DOD’s! See all the Moist-packed Seeds from the Shop.

Trillium grandiflorumAnd here’s the link for the ARGS Bulletin -1991 (open as a pdf). It contains great articles like: Saga of a Woodland Garden by Harold Epstein and Hepaticas and Anemonellas by Jeanie Vesall to mention just a few…

Trilix (Latin) = having a triple thread

If nothing else about wildflowers, one image can still thrill anyone  – the white carpeting of the woodland floor when Trillium grandiflorum is flowering; in southern Ontario sometime from late April to May.  Unfortunately, our car committed suicide, so I took this picture close to home in a remnant neighbourhood forest. You’ll just have to imagine this small patch of Trillium multiplied by hundreds, as it happens in the wild wooded areas.

Trillium grandiflorum

Trillium grandiflorum – Large-flowered trillium

Not that the provincial flower of Ontario needs a description; it is all about the number 3: 3-petaled white flowers (rarely pink) with 3 green sepals above a whorl of three leaves. Usually as they age the white flowers turn light pink. Unfortunately, it goes dormant by mid-summer but after the spring display we can forgive this little shortcoming.  Sometimes, individuals with green bands on the petals can be spotted – they look interesting but it’s said to be a result of a phytoplasma infection.

Mixed in with T. grandiflorum is often Trillium erectum – Wake-robin trillium, Stinking Benjamin. It displays stunning dark-red flowers above the foliage – three pointed petals framed by 3 green or reddish green sepals. The scent of the flowers is the source for the common name Stinking Benjamin – they emit odours to attract carrion flies, which are their main pollinators.
