Detailed Information
Flower: 
![[photo of flowers]](/udata/r9ndp23q/pink/spreading-dogbane_0704_092446.jpg)
Bell-shaped flower, pink to white with pink stripes on the inside, 1/3 inch long, with 5 flaring lobes that curl back. Flowers are in groups of 2 to 10 at the end of stems that branch out from the leaf axils in the upper part of the plant, or at the end of a leaf branch.
Leaves and stem:
![[photo of leaves]](/udata/r9ndp23q/pink/spreading-dogbane_0727_093656.jpg)
Leaves are 1½ to 4 inches long and up to 2 inches wide, generally oval with pointed tips and a short leaf stalk. They are toothless, usually hairy underneath, sometimes have a slightly wavy edge, and may be drooping. Attachment is opposite. The branching stems are often more horizontal than erect, as if under too much weight from the flowers. Stems are green or red.
Fruit:

Fruit is a slender pod 2 to 6 inches long that ripens from green to a dull red.
Notes:
Spreading Dogbane is fairly common along roadsides in Minnesota but the small flowers make it inconspicuous, until fall colors turn it bright yellow. Then it is hard to miss the small patches scattered along highways and county roads. A big mass we found along a roadway in Cass County (see more photos below) was a real treat.Native Plant Nurseries, Restoration and Landscaping Services ↓

Found a patch in my yard. What a surprise!

We have 160 acres that hasn't been farmed since the 1950's. The wildflowers are making quite a comeback and the side of one huge hill is covered with these. When you get hundreds of plants together they have a very sweet smell.

Along trailside, SE corner of park. Bell shaped flowers are very similar to Lilies of the Valley with a wonderful fragrance of their own.

Lots of this in bloom right now in the northeast corner of Itasca County.

I would love to find this in Douglas County, esp. Alexandria area, to collect seed or if appropriate dig plants. Can anyone help me out? None of the native plant sources that I know of have seed or plants.

These grow wild in my natural environment yard area. They pop up, literally, in late May. A sprig comes out of the ground and at about 18" tall starts to leaf out. Provides a very pretty foliage and bloom.

Tons of this on our farm. If the gentleman from Alexandria wants some, he is more than welcome to it! We are about 30 miles from Alexandria.

Lot of this growing on our hill down to the lake. It's been a drier summer, so not as many blossoms or are they getting too crowded? Pleasant sweet fragrance.

I have been noticing it in Blue Earth county now. Can anyone tell me if this gets as tall as four and a half feet tall? Is there an apocynum x floribundum in MN?

I just noticed these this year across the street, around our mailbox in Kanabec county and in our woods around our house in Pine county. We live on the county line so our mailbox is in a different county than our house is.

This prolific "weed" appeared for the first time in our driveway ditches this summer. At first, we mistook it for milkweed. But the similarity is superficial. I suspect one had best be careful to control the spread.

I saw this along an in-town walking trail in North Branch right off Hwy 61.

Saw these beautiful little things up at Gooseberry Falls this first weekend of August. Loved their little striped flowers.

We have a small but increasing patch of this in a clearing along West Victoria St. in the Kenwood area of Duluth. We cleared out a huge thicket of buckthorn and tansy almost 2 years ago (autumn of 2017)in this area, and discovered several species of wild plants that had been holding on for dear life under the heavy cover of the buckthorn. The dogbane was one of them.
The area is dry and rocky, and gets sand and salt tossed up by the snow plows. There is a woods to the north of this small clearing, and some trees to the east which give some shade but it is mostly sunny. We are encouraging the dogbane and the other natives to take over this patch of land.

These weeds may be beautiful however if they get into your garden they are horrible to get rid of!! Use caution where you are planting!!! No joke the roots are an inch in diameter and creep under for yards- any recommendations on how to get rid of it?

Found these up along the hiking trail just past Virginia (lookout mountain)

I noticed the pretty little bell shaped flowers while walking at Lake Elmo Park Resrve in Washington County.

Found in my backyard next to my neighbors fence, growing through the base branches of a lilac. We live near a preserve, in a landscaped neighborhood, through which deer and other wildlife regularly wander, which may explain how it came to be here.

On the edge of Luce Line trail towards Hutchinson. Love the candy cane stripes on the flowers!

We have 7 acres, mostly woods surrounding about an acre+ for our house and gardens, and a hill for the septic which faces south and is planted with natives. I planted a rain garden 2 years ago, and put in a couple dozen different natives, and then dogbane sprouted a couple of years ago. Last year a few dozen plants surrounded the rain garden, and this year they are thick, drowning out much of the garden.I ripped out the dogbane in the rain garden and will be taking out much of the rest. It appears to come up like milkweed, with underground roots reaching in all directions and popping up everywhere. Pretty but incredibly invasive.
