Early Spring Native Flowers: Bloodroot

One of Minnesota’s earliest native wildflowers is bloodroot, (Sanguinea canadensis). Given its name, you might expect a scarlet or crimson flower. In fact, it blooms ice-white with a sun-gold center, though some emerge light pink. They look out of place, so stark and fresh among the remains of last year’s woodland growth and garden detritus. Its name refers to the toxic red-orange sap in the rhizome or root.

Each bloom emerges wrapped in a single curling leaf like a little blanket. The leaf remains curled until the blossom withers and then unfurls into a rounded leaf with a varying number of lobes. The leaves range in color from light green to blue-green depending on the plant’s age and condition. In its natural setting, bloodroot often grows along woodland edges, which provide sun in early spring and shade when the trees leaf out. In my garden, it grows along the edge of an arbor vitae hedge and under an ash tree. With shade and regular watering, bloodroot creates a pretty ground cover that lasts all summer under deciduous trees. If they aren’t watered during summer’s hot, dry spells, bloodroot leaves just go dormant until the following spring.

Native bees, honey bees and beetles pollinate bloodroot, which also can self-pollinate. Fertilized flowers form elongated capsules that enclose spherical seeds colored black, red, or brown. Here’s what’s special about bloodroot seeds: Each produces an elaiosome, an attachment containing lipids, amino acids and other nutrients. Attracted to these nutrients, ants carry the seeds back to their nests and feed the elaiosomes to their larvae. The ants either discard the remaining seed in a separate chamber of their nest, or toss it back out onto the ground. Either way, this process, called myrmecochory, helps ensure that the bloodroot seeds are dispersed for germination. Other spring wildflowers, such as violets, trilliums, hepaticas and Canada wild ginger, also form this mutual relationship with ants.

A member of the poppy family, bloodroot is native to much of eastern North America from Nova Scotia south to Florida, west to Manitoba and south to Texas. Native Americans used the plant’s red sap to make paint and to dye clothing, leather and other items. It blooms from March to May in Minnesota woodlands and was one of the first native wildflowers that I identified in the woods at our cabin years ago. The plants in most of these photos grow in our backyard. They hold special meaning for me because they were a gift from my aunt, who grew them under her trees for decades. They remind me of how she nurtured my love for nature when I was young.

Spring: Inconsistent as Usual

Striped squill (Puschkinia scilloides), Siberian squill (Scilla siberica) and crocus bloom before last week’s snowstorm.

Spring in Minnesota is as fitful as ever — in other words, it’s one of the few things that remains normal during the pandemic. A week ago, Saturday was sunny and 70 degrees. Honey bees explored the squill patch and the first bloodroot blossoms unfurled white and gold. Twelve hours later, a cold front settled over the state. More than five inches of heavy, wet snow buried the garden and coated every bud, twig and trunk. Fox sparrows scratched and dug under the garden hedge sending snow, leaves and dirt flying behind them. A chubby American robin plucked the few remaining crabapples from a small tree. When the air warmed above freezing midweek, a few flowers were wilted and tinged with brown, but those that still had a covering of snow perked right up.

Sticky snow transformed a greening world back to winter black and white.

Traces of snow linger in the shady, northern corners of the yard, but most areas look like spring again — for now. While almost all of Minnesota’s record-breaking April snowstorms have occurred mid-month or earlier, that’s not always been true. Remember that April 29-30 storm in 1984? It dumped 9.7 inches of snow on the Twin Cities to close out the month. It’s all part of a typical Minnesota spring. Here’s a look at what’s growing in the backyard now that the snow has melted.

Bright green moss and its spore capsules are a refreshing sight after the snow.

Bloodroot (Sanguinaria canadensis) is one of the earliest spring wildflowers to bloom in Minnesota. Each flower is wrapped in a single leaf before opening.

A honey bee (Apis mellifera) in the Siberian squill is the first one I spotted this year.
