Detailed Information

Flower: Flower shape: 5-petals Cluster type: spike

[photo of flowers] Flowers are about 1 inch across, with 5 blue petals and a cream-colored center ring. The petals have pointed tips, a vein down the center, and wavy or ruffled edges. A long curving style protrudes from the center. Flowers are clustered in a spike up to 30 inches long at the top of the plant, or in smaller clusters arising from leaf axils. Clusters may be sparsely or densely packed.

Leaves and stem: Leaf attachment: alternate Leaf type: simple

[photo of leaves] Leaves are 3 to 6 inches long and ½ to 2 inches across, generally egg-shaped or oval, tapering to a sharp point at the tip. The leaf base tapers to narrow leaf stalks, abruptly when the base is more rounded. Leaf edges are serrated; the upper surface is rough. Leaves become gradually smaller and more narrow as they ascend the stem. Attachment is alternate. The main stem and leaf stalks are both hairy.


This species was formerly known as Campanulastrum americanum.

I was surprised to see these growing . Our grandson asked me what kind of flower it was, so I had to look it up. We have several lplants in one area growing.

We see these in several areas of wooded pasture that we own. Very colorful among the greens of the wooded areas.

Oh neat! A specimen of this species appears to have volunteered in the midst of my yard's prairie restoration!

In the backyard I planted the "Shady Woodland" seed mix from Prairie Moon Nursery in the fall of 2009. This year we have tons of American Bellflower.

While on the lookout for the European creeping bellflower which I am battling in our yard (it is endemic in our neighborhood), I found one of these native specimens. Hoorah! Thanks for helping me identify it.

Found this last year on the top of the bank of the Minnesota River right next to some Obedient Plant. What a wonderful mixture. This flower is one of the prettiest natives I have seen.

I saw American Bellflower growing in partly sunny openings at the edge of the Cannon River floodplain in Dakota County and in the floodplain of Prairie Creek just south of Cannon Lake in Rice County.

One of my favorites. So pretty along Jensen Lake in Lebanon Hills Park, tall and blue, after the majority of woodland flowers are done.

Saw these blooming this weekend at lake Louise state park, abundant in woodland understory along trails.

I could only wish European creeping bellflower be endemic, restricted to, one neighborhood in St Paul. I propose the term epidemic. It is certainly beyond invasive. Difficult to eradicate. Glad to know our native American bellflower is annual. That means I should manage for disturbance around the single plant I observed on our land last growing season. Out in full sun, but fairly heavy, moisture holding clay loam.

I saw these growing in the bluffs Winona County, Plowline Trail on July 19, 2017. Beautiful

I first thought this was the invasive alien and was delighted to find it was native. This woods (a woodland at the time of the original survey) has treasures!

I suggest you also include purple and pink as a color for this flower in your search engine. Right now it only comes up as blue. The one I photographed today (posted in Botanical Wanderings) seems to me to be somewhere between pink and purple.

Tim, tricks of the light can affect color perception, especially when the sun is low, and digital cameras are susceptible to such effects. That seems to be the case with the image you posted on Facebook. American bellflower is pretty consistently blue.
