Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Identification of artichoke-like plant in Idaho
Answered by: Nan Hampton

QUESTION:

There is a plant/weed growing in the front yard, my mom says it is a flower I say a weed. It looks a lot like an open artichoke and is the same size. It is green except on the tips where it is deep purple. I have searched high and low and can't figure out what it is. Please help! Thank you

ANSWER:

Cynara scolymus, the edible globe artichoke, is a native of the Mediterranean and introduced here as a food plant.  Here are more photos and information from Plants for a Future.  It is a type of thistle.  There  is also Cynara cardunculus (cardoon), its wild introduced relative.  Here are more photos and information from Plants for a Future.

There are other thistles that occur in Idaho.  The native ones in the genus Cirsium are:

Cirsium brevistylum (Clustered thistle) and here are photos of the plant from CalPhotos University of California-Berkeley.

Cirsium canescens (Prairie thistle)

Cirsium edule (Edible thistle)

Cirsium flodmanii (Flodman's thistle)

Cirsium foliosum (Elk thistle)

Cirsium scariosum (Meadow thistle) and here are photos from Southwest Colorado Wildflowers.

There are four thistles that are classified as noxious weeds in Idaho.  They are Cirsium arvense (Canada thistle), Carduus nutans (musk thistle), Onopordum acanthium (Scotch thistle), and Centaurea solstitialis (Yellow starthistle)—all are Eurasian imports.

Here are more photos and information on:  Canada thistle from the National Park Service, Musk thistle from Plant Conservation Alliance's Alien Plant Working Group "Least Wanted". and   Scotch thistle from Texas Invasives.

Perhaps your flower/weed is one of the native or introduced thistles.  If you have photographs of it and don't recognize it in the ones I've suggested above, please visit our Plant Identification page to find links to several plant identification forums that accept photos of plants for identification.

Now, whether it is a wildflower or a weed is up to individual interpretation—one person's weed is another's wildflower!
