Shrubs of the Week: Rosa rugosa Plus

{The images and writing for this bygl-alert is from Joe Cochran, the Curator of OSU’s Secrest Arboretum at the Ohio Agricultural Research and Development Center in Wooster, Ohio}

  What a difference a day makes!  I awoke Saturday morning, November 19, to cold, blowing flurries along Granny Creek in Knox County. It was a mere 14 hours prior that I was strolling through the arboretum in short sleeves marveling at the autumn splendors. On trying to decide on a Shrub of the Week, it was soon evident that it would need to be Shrubs of the Week. It was the middle of November and the...

Tree of the Week: Ginkgo biloba

  Ginkgo leaves this past week or weekend or this very day are falling, or have fallen, or are still dangling golden earrings on the tree, or yet have a touch of green, or fall with the first snow: All at once, almost quantum-esque, depending upon location, within Ohio, or on one side of the street, or dependent upon the condition of the tree. Don’t believe me: check it out.  It is certainly one thing though: The Tree of the Week. Or is it merely one, or is it two, or both one and/or two?. Read on.

First Freeze of Year in NW Ohio

Well we knew we could not avoid it forever.  The fall temperatures have been enjoyable.  Last night in NW Ohio, temperatures dipped to 25F.  Our average first freeze of the fall season occurs about three weeks earlier, and our first average measurable snowfall is just 2 weeks away.  Last night's low temperatures should have finally taken out those annuals and tender perennials that we have gotten to enjoy for an extended time this year.

 

While there were a couple frosts prior to last night's freeze, many herbaceous plants where still going strong.  It has been wonderful to...

The red maple (Acer rubrum) above and the other images were all from Saturday morning, November 5, in my yard and the nearby Johnson Woods Nature Preserve near Orrville five miles away.

  Maples held sway in their many iterations, from the luminosity of sugar maples (Acer saccharum) at Johnson Woods, to the unusually foliated hornbeam maple (Acer carpinifolium) in the ChatScape.
