I have both the single and double bloodroot in the garden, and appreciate each. However the Sanguinaria canadensis f. multiplex, the  double form, have an exquisite shape. In spring these give you dramatically beautiful blooms in the shade garden, with the white flowers showing up well in the shadowy areas. Although the flowers look exotic, they don’t mind a zone 3 winter.

Here the Sanguinaria canadensis f. multiplex (double bloodroot) are just emerging from the soil in spring. Each beautiful flower bud rises up with a leaf curled around it. On the right you see the initial appearance, and on the left the leaf is starting to part.

As the leaf uncurls more, the flowers rise up and unfold, so you begin to see hints of a the multitude of beautiful petals.

It seems that this perennial can be listed in different ways, and I sometimes see the double labelled as  ‘Flore Pleno’. Sanguinaria canadensis f. multiplex is extra generous with the petals, the exquisite flowers resembling waterlilies. The pure white colour really stands out against the background in the shade. I have two of these double bloodroots, and this year they have bloomed a week before the single version. The double forms are supposed to last much longer than the singles. However,  mine only lasted a little over a week, a brief but beautiful flowering. They are definitely worth finding space in your shady garden. I go out each day to admire the blooms, but the light colour can also be glimpsed from my windows.

Bloodroots are native to the woodlands of Eastern Canada, but these are doing fine in the Parkland of Alberta. I have these planted in a very shady area, between the trees. There is a lot of decomposing leaf matter in this garden bed. Although these perennials are supposed to be ephemeral with the leaves fading back after spring, mine keep the foliage all summer, and their unique shape looks good. Perhaps the cooler summers help sustain the plants.

The Sanguinaria leaves are very decorative for a perennial that might hide away for the summer in some areas. The large flat leaves are deeply lobed and stiff, so they make a nice green foil for other plants in the garden. The bloodroot leaf above is looking shiny in the rain. The plants are about 18 cm  (7 in) tall, with the flowers about 23 cm (9 in) in height.

Here  are more pictures of Sanguinaria canadensis (single flowered bloodroot). I’ve now paired the Sanguinaria with some pretty blue Chionodoxa forbesii.

Even if you don’t have a woodland, the double bloodroot will do well under the shade of a tree, to bring a little part of the Eastern forest to your garden.

    Those are incredibly beautiful, I will try to find some for my shade garden. I love they way the flower bud is visible just above the still furled leaf.

    Rebecca, the blooms are gorgeous, and they flower so quickly after they first appear. I have some other perennials in front of them, to flower later on, too.

    Such a distinctive and pretty plant. I absolutely love the way the leaves wrap around the buds – so sweet and protective.

    Must get the doubles. All the photos are lovely but the last one is outstanding.

    The Garden Ms. S, it is fascinating the way the leaf and bud rise up and unroll. These are another perennial that just don’t look like they would survive our winters, but do just fine.

    Irena, the double flowers are outstanding in appearance, with the layers around, and the slight up curve to the petal tips.

    The both of them is nice, but I like the double form best. It is one of my favorite plants in spring.

    Marit, the shape and arrangement of the double form definitely makes them stand out. I have some Brunnera, with airy blue flowers neat them, and like the combination.

    They are beautiful plants – I too have both but prefer the double which also seems to last longer.
    I had a look at the Royal Horticultural Plant Finder (a plant bible for names!) and they have two different doubles listed – f. multiplex and f. multiplex ‘Plena’.
    f. apparently means (botanical form). Heaven knows what the actual difference is…..if any, unless the plant is under a microscope.

    Easygardener, perhaps the wind and rain got my flowers, as the doubles didn’t last much longer than the single form, although they are supposed to, since they aren’t fertile. I think the f. multiplex might be the correct wording, but sometimes I see them listed on tags as flore pleno around here, but I think that is just a generic reference to lots of petals. I do enjoy the wonderful presence that the extra petals give to the flowers.

    Northern, Is the double bloodroot a cultivar? This is really pretty – I’ll have to look for some! :-)

    Shady Gardener, it gets named in different ways, but the the fully double form is supposed to be f. multiplex, and the semi double is supposed to be ‘Flore Pleno’ or ‘Plena’. The double is sterile, because what used to be the reproductive parts are petals now, so the flowers should last longer that the single flowers. They are very hardy and pretty.

    where can I buy the seeds for this plant and what are the growing conditions re type of soil, sun exposure,fertilization,etc.

    Augusto Fernando, the double bloodroot is sterile, so it won’t get any seeds. That is why the petals last longer on these flowers, compared to the regular bloodroot. They grow best in woodland type conditions. Mine are growing under some trees, and I leave the leaf litter on for them to enrich the soil. They grow well in part shade.
