Detailed Information

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

[photo of flowers] A small group of flowers cluster at the top of the stem and at the end of branches arising from the upper leaf axils. Flowers are about 1 inch across, 5 notched petals that spread out, then back as the flower ages. The color ranges from pink to white. 10 stamens and a long, 2-parted style protrude from the center.

[photo of atypical hairy calyx] Behind the flower is a slender, tubular, light green to reddish calyx about 1 inch long with 5 short triangular teeth at the tip, straight across at the base, and usually smooth, sometimes minutely hairy.

Leaves and stems: Leaf attachment: opposite Leaf type: simple

[photo of leaves] Leaves are generally oval or egg-shaped with blunt or pointed tips, up to 4 inches long and 2 inches wide, with 3 prominent parallel veins and little or no stalk. The leaf edges are smooth and often somewhat wavy. Attachment is opposite, sometimes with smaller leaves growing from the leaf axils. Stems are erect, smooth, may be branched in the upper plant and single or multiple from the base.

Fruit: Fruit type: capsule/pod

[photo of developing fruit] The calyx persists and holds a capsule of numerous

Notes:

Bouncing Bet is likely under-reported in Minnesota. The flowers resemble those of a Phlox, but the leaves with 3 prominent, parallel veins easily distinguish it.

A very full, fluffy triple-petaled version of this wildflower in a rich pale pink blooms everywhere in the rural ditches near Dundas, MN. It is lightly fragrant during the day but at night has a rich, haunting smell like very sweet grape juice. I have found this planted in front of pre-1900's old graves and wonder if this beautiful extra double form might have been gradually selected by gardeners. Perhaps it escaped from gardens and cemeteries near by.

This grows weedy throughout the twin cities metro area. Happy to have finally figured out the species, as it has been stumping me for some time! I was checking the Silene and Phlox genus for answers.

Noticed this blooming on July 20th in Duluth MN in Chester Park and elsewhere. The variant I found displays several six-petaled flowers amongst a greater number of five-petaled flowers.

Bouncing Bet is now in many places around Staples, MN - saw large areas covered with blooming plants when visiting a rare native plant community in a nearby WMA north of Staples (July 18, 2017). Seemed to be many other invasive plants mixed in with flowering desirable native plants along the roadsides.

First time it has shown itself here on our property. Twenty plants with pale pink blooms. Growing along roadside ditch amongst the raspberries and vetches.

Saw Bouncing Bet yesterday growing along the ditch down my street. First time I have noticed it. At first glance I thought it was a type of campion plant, but the flowers looked different, so I took photos to ID at home. August 2, 2017.

A cluster of this just showed up along the edge of our backyard prairie garden.

I noticed these plants in a horse pasture a mile southwest of Long Prairie in early July this year.

This is growing in a couple of flower beds at a golf course. I am trying to eliminate it. The plant is sending rhizomes every where! It comes up through hostas and lilies. It is a very invasive plant.

This is easily misidentified as a campion! Spreads easily and quickly in twin cities climate. Dominates the area once one plant establishes.

On the left hand side of the road going down to the boat launch. Took me three hours to figure out it has both single and double flowers. This one was a double.

Large numbers of these blooming 22-Jul-2019 in the mowed shoulder along Cass CR 10 (Scenic Byway) to Pennington, as well as along Smurler Road SE.

Its been growing for the last 3 yrs in my flower beds around the house. Never planted them. Let them show themselves before deciding if weed or keeper. Decided to was a keeper. More have popped up since.

On the Munger Trail near Aitkinson. A few plants with single white flowers in full sun.

Very pretty light pink flowers where the hill meets the beach. (Read: very sandy soil and lots of sun.) Starting to spread like crazy, tho.

I first saw this at our abandoned family's homestead in northern Nebraska, and my mom said she remembered playing among these flowers when she was a little girl. Besides being like white phlox, they smell sweet & I was happy to find them growing "volunteer" (a.k.a. wild) around my house in Minnesota. If you ever get them started you will have them for as long as you want.
