ArborEatum is just around the corner: next Tuesday, October 24. What fun it is: a friendly no-fee gathering of people who love to grow, culinaritize, eat, and drink various foods from landscapes and gardens. Come one come all to the Miller Pavilion at Ohio State University’s Secrest Arboretum, Tuesday, October 24, from 5:00 pm on. Eating and walking. Bring your offerings or just your appetites.

  Friday the 13th has just passed and in some sort of dyslexic dystopia, the 31st is just around the corner and Halloween will soon arrive. So it seems only right to write of that which is wrong - or shall we say – wicked, as in Wicked Plants. There is an excellent book by just that title, “Wicked Plants: The Weed That Killed Lincoln’s Mother and Other Botanical Atrocities” by Amy Stewart. I recommend it, but for now, let us take a little trip into the world of some plants wicked this way come, through the house of horticultural horrors, guided by myself...

I often ask students in Master Gardener classes "what is a buttonwood tree?" to illustrate the challenge with common names of plants. Unlike scientific names, there is no recognized governing body that standardizes common names of plants. Consequently, plant names may vary widely (wildly?) owing to differences in the cultural backgrounds of people living in different geographical regions, among other things.

I first reported on Magnolia Scale (Neolecanium cornuparvum) this season in June when the maturing females were "puffing-up" and pumping out honeydew (see BYGL Alert, "Magnolia Scale is Pumping-Out Honeydew," June 16, 2017).

As a committed crabarian, I cringe along with everyone when driving into a town or walking along a street and seeing the barren, defoliated canopies of certain crabapples this summer and now into the fall. Out darn scab! (double apologies to W.S.).

Osage-Orange has long been one of my favorite trees. What's not to like? Grows anywhere, has glossy, dark green foliage and deeply fissured orangish-tan bark with great winter interest. Just don’t stand or park your car under female trees at this time of the year.

I spent a rewarding evening yesterday learning from members of the Cincinnati Chapter of the Professional Grounds Management Society (PGMS) while leading a diagnostic walk-about at Spring Grove Cemetery and Arboretum. Our first stop was to view a large oak sporting an "aerial display" of Porcelain-Berry.

Need 100 one and a half gallon ornamental grasses planted?  Just put out an "all hands on deck" call to OSU Extension Master Gardener Volunteers and they get the job done in  less than an hour!   This is exactly what we did in Clark County in order to complete our border planting in the Snyder Park Gardens and Arboretum (SPGA).  The border consists of more than 4000 daffodil bulbs, a river of daylillies and now Schizachyrium scoparium 'MinnblueA' or Blue Heaven little bluestem.  The idea is that after the spectacular daffodil bloom in the early spring, the bluestem will come up and help to...
