Sanguinaria canadensis ‘Multiplex’

Double Blood RootSanguinaria canadensis ‘Multiplex’, commonly known as Double Blood Root is one of the eastern seaboard’s most lovely spring ephemerals, (that is to say, perennials which emerge with the first sweep of warm weather, and almost as quickly pass, retreating over the next few months into summer dormancy). Here in New England, Double Blood Root begins to poke through the brown earth in mid April, displaying pristine white multi petaled water lily shaped blossoms cupped in barely visible blue green leaves. We always hope that the weather conditions will not be too hot and relatively calm when our Blood Root opens. Too much wind or warm temperatures will shorten the floral display.

Double Blood Root stands on short stems reaching just under 6″ tall. It grows best in rich, humusy, but well drained soil in a partial to deeply shaded site.  The rhizomes slowly spread to from dense clumps over time and when severed, exude a deep red liquid, hence the common name (sanguine = bloody). As the blossoms fade, the attractive blue green kidney shaped foliage grows larger in size, photosynthesizing to store energy for the roots below. It is advisable to mark the spot where Blood Root is growing. By mid summer, these attractive leaves will begin to fade into dormancy, and you might easily disturb the area by over planting. Good companion plants for Sanguinaria are mid season bulbs, Tillium, Podophylllum, AsarumEpimedium, Iris cristata, Woodland Phlox, and Brunnera.

  1. My daughter has a large stand of double blood root. and may be moving. We wish to transplant these gems. When is the best time?

  2. Fall is the best time to dig and divide. However if it not possible to wait, dig up as much of the clump as possible and transplant the clump for fall division.
