Perhaps November is really not the time of year to try to identify roadside roses. Sure, the hips are lovely, and they certainly look as though they should be distinctive. Lots of trees are easily identified by their fruits alone, so why not roses? How difficult could it be?
I confess right up front that while I appreciate roses as much as the next person, I am not a rose aficionado, one of those people for whom roses are the sole reason for existing on this planet. I enjoy their colors, their fragrances, and their abundance of brightly colored fruits in the fall, but I don’t dedicate my life to their propagation. Perhaps if I spent a little more time among the roses, however, I wouldn’t find myself in my current predicament.
Last month I took some nice photos of some of the rosehips I found growing along Route 28N. It was early morning, there had been a crisp frost overnight, and I had my new lens to play with. I ended up with a nice image or two, and all was fine…until today, when I decided to write up an article about our local roadside roses. I mean, if you are going to write about something, you really should be able to identify what it is, beyond the obvious (rose). It turns out that sometimes this is easier said than done.
I started where I always start when trying to identify plants: my Newcomb’s Wildflower Guide. It listed several species, and had color illustrations of flowers, leaves, and even some of the hips. But since all I had to go by were some photos of the hips, I thought I should try to narrow the field by finding out what species actually grow in New York.
According to the Revised Checklist of New York State Plants, by Richard S. Mitchell and Gordon C. Tucker, New York is home to no less than twenty-eight species of roses, seventeen of which are non-natives, and two of which are endangered. Unfortunately, this checklist is just that: a checklist. It doesn’t give tips for identifying the plants it lists, nor does it provide a list of plant locations.
So, I next turned to the state’s new on-line nature information website: New York Nature Explorer (http://www.dec.ny.gov/natureexplorer/app/). It’s supposed to be your one-stop-shopping location for identifying and learning about the plants and animals of our fair state. I typed in “rose” and hit “search.” It turned up exactly one rose in the entire database (although it also listed things like rose pagonia – an orchid— and rose-breasted grosbeak—a bird). What happened to the other twenty-seven?
Not to be discouraged, I went to Google and ran searches for each rose on the checklist (it’s been a long morning). I found lots of photos of flowers, but few of hips. And none seemed to match mine. The light at the end of the tunnel was getting further and further away.
Turning back to Newcomb’s, I counted nine species of roses, all of which occur in New York. The other eighteen from The Checklist that were not listed are all non-natives, apparently garden types that jumped the garden wall. I figured that I had found my best possible source for ID help. Ironically, it was where I had started about four hours ago.
A couple, like the swamp rose (Rosa palustris), were easy to eliminate from my search – they require wetlands, or at least habitats that are more amenable than the dry, salty side of a highway. Smooth rose (R. blanda), as you might guess from its name, is a relatively thornless species. Looking closely at mine, it didn’t qualify. Not only was the stem covered with thorns both large and small, but so were the stipules at the end of the fruit.
The fruit of Rosa rugosa, a common escapee, look like balls that have been flattened on both ends. The fruits on my specimen do not fit this mold. I was ready to settle on it being a pasture rose (R. carolina), but all photos and drawings I found of this species were nowhere near as thorny as mine. My hopes of success were now pretty well dashed.
But that’s the great thing about being a naturalist—I have an undying curiosity to know the answer. I may not learn the identity of these roses today, tomorrow, or even this year. But you can rest assured that come summer next year, when the roses bloom and fill the air with their perfume, I will be out there with my field guide (and camera) in hand, determined to identify these plants. Even if I have to send specimens to the authors of The Checklist.
