Trefoil Foiling Lawns, Landscapes, and Naturalized Areas boggs.47 Fri, 07/14/2017 - 11:20
The bright yellow floral display currently blanketing some lawns and roadway right-of-ways is being produced by Birdsfoot Trefoil. The yellow flowers are smaller than dandelion flowers, bigger than those of black medic, and resemble buttercups from a distance. This non-native plant was imported with good intentions, but is now gaining weed status in lawns, landscapes, and naturalized areas in Ohio. Yet another example of unintended consequences with introducing non-natives.

Coneflower Calamities boggs.47 Tue, 07/11/2017 - 18:15
Participants at yesterday’s S.W. Ohio Diagnostic Walk-About viewed two problems on purple coneflowers; one potentially more calamitous than the other. The first was the handiwork of the Sunflower Head-Clipping Weevil (Haplorhynchites aeneus) which included dangling seed heads and stems that looked like soda straws. The second were stunted plants and deformed plant parts caused by the phytoplasma disease known as Aster Yellows.

Weed of the Week - Oriental Bittersweet stone.91 Thu, 07/06/2017 - 10:59
There is nothing "sweet" about Oriental bittersweet. This non-native species appears to be popping up, and then growing up, in NW Ohio. While it was an occasional invader in natural areas, forests and fence lines, more and more people are having to manage this invasive species.

Perennial of the Week - Liatris stone.91 Tue, 07/04/2017 - 08:55

 

Commonly called blazing star or gayfeather, this perennial produces tall spikes of bright purple flowers that resemble bottlebrushes above the green strap-like foliage. This perennial is in the Asteraceae family and there are 32 species that occur throughout much of North America from southern Canada to northern Mexico.

 

The individual flowers open from the top to the bottom, unlike most plants that open from the bottom upward as the spike develops.  Flowers of this perennial act like insect magnets - attracting both bees and butterflies.  Flower spikes can also...

Summertime...And Flowers Are Boooming chatfield.1 Mon, 07/03/2017 - 23:16

Emerson says: The Earth laughs in flowers.  Springtime, though, is when we tend to think of such mirth.   Summer is now our season, yet floral beauty continues to reign. Following are five of the boys and girls of summer.

 

 

  Above is the spectacular and aromatic flower of Stewartia, a member of the camellia family (Theaceae), photographed at Secrest Arboretum where Joe Cochran, Paul Snyder, Matt Shultzman, and the legacy of Kenny Cochran, hanuve resulted in numerous stewartias planted in recent years.

A Single Leaf Diagnostic Case Study boggs.47 Sat, 07/01/2017 - 12:47
I would never recommend bringing a single tree leaf to an Extension office or garden center and asking the question, “what’s wrong with this tree?” However, sometimes a single leaf can speak volumes. Just accompany me or Jim Chatfield on one of our diagnostic walk-abouts (stand-abouts?) and we’ll prove it to you!

Shrub of the Week: Smokebush chatfield.1 Mon, 06/26/2017 - 08:13
Smokebush or smoketree (Cotinus) is puffing away right now, providing the almost ethereal inflorescences that give it its name  and alternates such as cloud bush, mist tree, wig tree, and Jupiter’s beard.

My Favorite Things - Plants - How About This One! bennett.27 Tue, 06/20/2017 - 07:30

I love plants and proudly claim the titles of plant nerd, tree-hugger, plant geek and any others like this.  Plants of all kind - perennials, annuals, trees, shrubs, vegetables, native plants, etc. intrigue and delight.  How can you not like them!  One of my garden plants that looks particularly good right now is Calamagrostis  x acutiflora 'Karl Foerster' or Karl Foerster feather reed grass.  This grass is stellar and it's no wonder it's used quite a bit in both commercial landscapes and home gardens.  'Karl Foerster' was named the Perennial Plant of the Year by the...
