Detailed Information

Flower: Flower shape: 5-petals Flower shape: bell Cluster type: panicle Cluster type: raceme

[photo of flowers] 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: Leaf attachment: opposite Leaf type: simple

[photo of leaves] 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 type: capsule/pod

[photo of 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.

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.

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.

Ann I am interested in contacting you about collecting some spreading dogbane. 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.
