Detailed Information
Flower:
Solitary flower at the top of the stem and at the end of the few branching stems. Flowers are 1 to 2½ inches across with many yellow dandelion-type ray flowers (petals). The 8 (occasionally more) green bracts that surround the flower are as long as or shorter than the petals.
The stem just below the receptacle may be slightly inflated when the plant is fruiting, but not when flowering. The flowers open on sunny mornings and close by noon. The closed flowers resemble a thin pod.
Leaves and stem:
Leaves are grass-like blades, to ¾ inch wide at the base and up to 1 foot long becoming smaller as they ascend the stem, toothless, generally smooth, almost waxy though may have very fine, sparse hairs when young, Leaves abruptly narrow near the base then gradually taper to a pointed tip, and clasp the stem. Leaves are usually coiled or curved at the tip, often in tight curls on upper leaves. Stems are smooth, green or with a whitish cast, may branch near the base of the plant or have multiple flowering stems.
Fruit:
Fruit is a giant dandelion-type plume about 3 inches across; the brown seed has a tuft of whitish hairs to carry them off in the wind.
Notes:
Meadow Goat's Beard is very similar in appearance to Yellow Goat's-beard, Tragopogon dubius, and found in similar habitats but is not as common in Minnesota as T. dubius. T. pratensis can be distinguished by deeper yellow flowers, the narrower stem just below the receptacle, bracts not extending beyond the rays, and the curling of leaf blade tips.Native Plant Nurseries, Restoration and Landscaping Services ↓

Have you seen this plant in Minnesota, or have any other comments about it?

First of all, THANK YOU for a terrific website! This is a pretty plant but very aggressive and spreading in our old hayfield. We'd like to eradicate it but don't want to use herbicides. If a true biennial, as you note, then I should be able to get rid of it over time by removing flower heads before seeds are set, correct? That's a whole lot easier than pulling, which is fun and relatively easy to do after a rain but becomes hard work after a few hours. My concern is that another website mentioned these plants taking up to 10 years before bolting and flowering! That sounds like a perennial to me. Any advice would be appreciated. Thanks for your time :-)

Judy, if you don't want to use herbicides then your only options are pulling and dead-heading. USDA lists it as a biennial, though as happens with many biennials, seeds may be viable but not germinate for some number of years.

We saw this plant in Lebanon Hills Regional Park. There were several in a disturbed area near Jensen Lake.

In my area the flower closes around 11:00 every morning. It has a flowering period of about 2 weeks before beginning to seed. Interestingly, the goats beard in my area does not curl its leaves, but has all other characteristics.

We have seen them along the road in our town. I do have a question though. I feel these would be pretty when "gone to seed" next to large pink poppies but it's hard to say if these weeks will align in the garden. Does anyone have a general idea what weeks in Minnesota they go to seed??? Thank you!😊��😊

Hi, Betsy. I know it's been two years, but in answer to your question, these plants are in seed now in my area in the first week of July. They are dramatic seed heads! (Today is July 4th and they're starting to blow away...)

These are done blooming in my yard, and now they just look ragged. Is it ok to pull them up or cut them down, or will that keep them from blooming next spring?
on: 2024-06-26 06:37:40
Beth, this is not a native species so feel free to pull it up or cut it down any time, especially before it has a chance to send seed off blowing in the wind. ;-)

Thank you!
