How to Plant Multiplex Bloodroot


Multiplex bloodroot (Sanguinaria canadensis f. multiplex), also known as double bloodroot, is a perennial plant that reaches a height of six to eight inches with double white flowers that bloom each spring. It also has blue green leaves that are kidney or heart shaped. Multiplex bloodroots grow in USDA Hardiness Zones 3 to 9 and should be planted in the spring or fall.

Step 1

Select a location in partial shade to mostly shady area of your yard. Naturally, it is found under the canopy of trees with some sunlight peeking through.

Step 2

Amend your soil, if necessary. The soil should drain well and be humus-rich. Mix in a couple inches of humus, which is available at your local nursery, if necessary. This will improve drainage and add the much-needed organic material at the same time.

Step 3

Adjust the pH, if necessary. Multiplex bloodroot prefers soil that has a pH between 5.5 to 6.5. Test your soil using pH test strips and add lime to increase pH or sulfur to lower it. The amount needed will depend on your results, so follow label instructions carefully.

Step 4

Cut the rhizomes. Unless you were able to purchase one at your local nursery, you will need to dig up an existing multiplex bloodroot and cut the rhizomes (root ball). You can cut them in 2-inch slices, being sure to leave at least one "eye" or bud on each piece.

Step 5

Dig holes that are about 6 inches apart. The hole should be 1 to 2 inches deeper than the length of the rhizome, but twice as wide.

Step 6

Place one rhizome in each hole with the eye facing up. Backfill the soil and tamp it down so there are no air pockets, which can cause root rot.

Step 7

Water the rhizomes well and cover with about 3 inches of hardwood or leaf mulch. Water to supplement rainfall as necessary. You don't want to keep multiplex bloodroots saturated, but you don't want to let them completely dry.
