Trientalis and other tuberous dicots

Trientalis europaea, whose german name „Siebenstern“ („seven-star“) is as poetic (for a german plant name...) as the plant itself (which is now a Lysimachia, as I just learned) is never grown as far as I know. A quick search did not show any source for plants. It is a charming simple plant even compared to the others in its previous genus Trientalis; pure white flowers on very thin stems, so they almost seem to float above the ground. It makes Anemone nemorosa look brash. Almost all flowers have seven petals, and most shoots carry one or two flowers. I will try to provide some pictures for the wiki when they flower.
I think their overall habit is better for natural and semi-natural surroundings than for pots; sadly, as it‘s one of my favorite flowers in the wild. They so rarely set seeds that I never saw any, and I am reluctant to dig some up, but maybe I will try some day.

> Nils's informative initial post mentioned Trientalis europaea, a charming woodland plant in the Primulaceae. Here we have Trientalis latifolia (T. arctica at some other parts of the Pacific Northwest). It's actually a geophyte in the broad sense, since it grows from tubers that spread on stolons. I think the tubers are annual, though. I've tried to ship it dormant with poor results, but it can be potted up if you dig a good cluster of the delicate plants. It is hard to establish, though, and I've wondered if it needs some microbial assistant present in the soil. Fortunately, it was already in my garden when I moved here, and has increased well with organic mulching and irrigation in summer.
> This is one of many plants of Mediterranean climate areas that can be thought of as geophytes, though dicots. One with a similar growth cycle is Lithophragma parviflora, which occurs mostly on rocky spots but for some reason has increased madly in the same bed as the Trientalis (it got there when I discarded a pot I thought was dead). The genus Lomatium (Apiaceae) is another, and one could mention the deciduous Lewisias, which I grow in my bulb house. How far does "bulbs" extend?
