To compensate for the lack of a pinkish bloodroot this year, we found this isolated clump of Sanguinaria with very large, almost gigantic leaves. True that Flora of North America mentions leaves up to 25 cm across for Sanguinaria, but we have never seen such exemplars until now.
PDN from US sells a Sanguinaria ‘Missouri River Giant’ with leaves said to be 8 inches wide (ie. 20 cm). Well, this one has even larger leaves. Of course that grown from seeds, there is bound to be variability, and we cannot give it a name ;)
Besides the leaves, I can tell now that the flowers are very nice, large and with pink backed petals.
But again, it is an isolated clump, from an area where strangely there are no other Sanguinaria plants, although Trillium is very abundant. The many, many self-sown seedlings around the ‘mother-clump’ also imply a very good germination capability.
Germination: sown anytime as long as the seeds are stored moist and follow a warm/cold cycle. Some seeds will start to germinate (root only) in cold storage by February, others later in the spring (root and shoots) but a percentage of the seeds will germinate completely (shoots) in the second year, it is variable.
