Geranium sanguineum var. striatum
jer-AY-nee-um san-GWIN-ee-um stree-AH-tum
Geranium sanguineum L. is the correct and accepted scientific name for the Bloody Cranesbill. This species was named and described by Carl von Linnaeus in Species Plantarum in 1753.
Geranium Tourn. ex L. is the correct and accepted name for the genus. It was originally named by and documented by Joseph Pitton de Tournefort. It was later described by Carl von Linnaeus in Species Plantarum in 1753. Mr. Tournefort is known for being the botanist who made a clear definition of the concept of plant genera. It would be very interesting to know how many genera he actually named that we think were named by Linnaeus.
Plants of the World Online (by Kew) lists 357 accepted species of Geranium. The 2013 version of The Plant List named 415 accepted species names (plus 13 additional infraspecific names), 398 species that are synonyms (plus 379 infraspecific names that are synonyms) and 214 names that are unresolved. The Plant List is no longer maintained.
Geranium sanguineum var. striatum is similar to the species but with larger flowers, maybe up to 1 1/2″ across. I have not measured the flowers so that is something I will have to do this summer.
When I moved back to the family farm in mid-Missouri in February 2013, I was happy to see descendants of the Geranium sanguineum I had planted in the early 1980’s were still here. I had moved into my grandparents (my mother’s parents) home after my grandfather passed in April 1981. My grandparents were exceptional gardeners and had HUGE gardens on both sides of the house, an apple and peach orchard, lots of grape vines, blackberries and raspberries. You might say if it could be grown here, my grandparents had it. I spent a lot of time with my grandparents and I guess their jor of gardening passed to me. My father was also a very good gardener as were his parents.
After I moved to the farm, I went ahead and planted the gardens on both sides of the house as grandpa had always done. I also made several new beds around the house and bought a lot of plants from Bluestone Perennials. The ancestor of the surviving Geranium sanguineum was from Bluestone.
There was an old raised concrete planted grandpa built all along the back porch. It had started crumbling so I removed it and made a new bed there which is where I planted the Geranium sanguineum. After I married and moved away in 1987, it became dad’s responsibility to mow the yard and everything. Needless to say, that wasn’t easy for him because he had his own yard, garden, and a full-time job.
He retired in 1996 and my parents decided to move to the farm. They had a manufactured home built and moved it where the garden used to be south of the driveway. Dad started using an area where the garden on the north side of my grandparents home was for his garden spot. Sometime after they moved there they chose to tear down my grandparent’s old house. Originally, they had given it to the Amish who planned on moving the entire house. The problem was getting it over the hump across the road where the railroad tracks had been. They found out that wouldn’t work so they tore it down and saved the lumber.
At some point, mom and dad didn’t take care of the old flower beds. The Hosta were mowed off (OUCH!) and the beds around the old fish pool were abandon and mowed down. Luckily, dad moved the Geranium sanguineum to the north side of their new home where they flourished. They sun in the morning and again in the afternoon.
Although I am not a “pink” person, you have to admire a plant that is determined to survive and please their caretakers with such a flush of flowers. They flower like this for several months then randomly until frost.
They like sun to part shade which makes them very versatile. The only problem is that they can become quite thick and can have a little problem with crown rot, especially in a damp summer in more shade and soil that is not well-drained. Thinning them out a little will help. If you wait until they crown rot, you risk losing them all.
They are always among the first perennials to send up new growth in the spring and they kind of remind me of strawberries. Actually, they grow quite similar to strawberries. They spread by rhizomes although I wouldn’t exactly call them invasive. They just kind of slowly spread. Perhaps in a different location they may spread more rapidly.
Even without the flowers, they look good. This photo was taken before they started flowering on May 1, 2015.
The flowers are a bright pink with maroon streaks. Looks pretty neat with the water on the petals.
There was an issue with crown rot in 2016 but they have recovered well. I cleaned out the dead stems and it helped a lot.
Origin: See Plants of the World Online link below
Zones: USDA Zones 3a-9b (-40-25° F)
Size: Up maybe 16” tall
Light: Sun to part shade
Soil: Average, well-drained
Water: Regular watering, drought tolerant once established
Propagation: Rhizomes in the spring
Concerns: Crown rot in crowded, damp conditions.
Temperatures were getting cooler, but the Geranium sanguineum withstood several frosts and just kept producing new leaves.
January 2018 had some VERY cold days and most everything was brown or gone. Basically, the only sign of green around the house is the Geranium sanguineum.
Geranium sanguineum is looking very well once again. I think I am going to transplant a few in other areas to see how they do. Maybe on the south side of the house.
There are several cultivars of Geranium sanguineum available online. Maybe someday I will try a few more.
There are also several Geranium and pelargonium organizations from several countries but I didn’t want to list them all here. At some point, I will add links to more of them on the list at the bottom right of the blog.
