[MAIPC] Five-fingered Aralia Spotted in Baltimore City

Sat Aug 4 11:11:52 PDT 2018

Olmsted rings a bell, I found Aralia planted and 'expanding' on the point near the river at the Vanderbilt Mansion at Hyde Park, ROVA back when I surveyed in 2002. I would imagine they might also have planted it at all their designs... which makes it a historically significant cultural landscape planting with observed invasive tendencies if abandoned (i.e. forgotten and allowed to sucker down). Easily removed. It was suckering at the location I surveyed. I'd be interested to know if it is spreading viably by seed.

Kate and I met at the Wyman Park Dell this morning. There are 2 patches of five-fingered aralia on the slope between the walkway in the Dell and Charles Street, maybe half a dozen plants each. It is virtually certain that they were planted, and it is possible the patches are slowly spreading. The Dell (which is a different park from “Wyman Park”) was designed by the Olmsted Brothers over 100 years ago and has been maintained as a planted landscape ever since, with varying levels of maintenance and replanting. It is not a natural area, nor does it abut a natural area. While eradication of these plants might be wise, there is a certain irony in removing them from an active infestation of porcelainberry, tree-of-heaven, etc.

We recently checked on your 2012 report and it is there (and expanded a bit I think). I’d love to get your input on where other spots are near by. We’ll likely have to wait to treat until next year.

All,
I identified this plant for Fred Walker who dropped by my office at Center for Urban Ecology in August 2012. I mapped his occurrence, based on his best description while I had EDDMapS opened on my computer: http://www.eddmaps.org/midatlantic/distribution/point.cfm?id=2415456
I found additional patches along MacArthur Blvd. in Cabin John. I mapped these using MAEDN but it was an early version of the app and I must've had some issue getting my report submitted for that location. I don't see my report in EDDMapS. I'll revisit the area within the next few weeks and report whatever populations I find.  Jil.......................Jil SwearingenInvasive Species ConsultantIn the Weeds410-200-7085

I’ve been keeping an eye out for this stuff since it was spotted in Arlington (10 years ago?). I haven’t seen it in any Fairfax stormwater ponds.

Invasive Plant Control (IPC) treated a huge flume of this crud in a mesic ravine at lower Donaldson Run Park in Arlington County, Virginia earlier this year.  Fortunately, we haven’t seen this non-native invasive plant in adjacent City of Alexandria yet.

I’ve treated small populations of this species in Spring Valley Park and in Linnean Park, both in DC.  Both were growing into the parks from adjacent yards.  I’ve never seen it on its own in a natural area.  There’s also a specimen in my neighbor’s yard in Greenbelt, and a nice hedgerow here!

I have treated it in Rock Creek Park (DC side), around the park police horse stables/community garden off of Oregon Ave.   that was at least 10 yrs ago, and I had checked for a few years after treatment but haven’t seen the area in the last 5-7yrs to know if it has rebounded at all or if it gave up the fight. 

I believe it is also called “Five Leaved Aralia” and what I treated looked exactly like what you have in the pics.  Medium sized, multi stemmed shrub 5-8 ft. tall (generally) and small very sharp thorns on the stems (at/near the base of the leaves). 

This is one of the only places that I have seen it in the DC, Md, Northern VA area however,  hopefully it is not more wide spread than we realize. 

Thanks for the heads up on the Baltimore County sighting, we will keep our eye out.

Hello MA-IPC, 

I wanted to alert the listserve thatI've spotted a developing stand of Five-fingered Aralia (Eleutherococcus sieboldianus) in Baltimore City. The plant, which does not appear to have been intentionally planted, has colonized approximately 35 square feet of an embankment in Wyman Park. The report has been verified on EDDMapS.  This is the first verified sighting of the plant in Maryland in EDDMapS since May 2016, and is the first in Baltimore City. My hope is that this is an isolated incident and that the plant has merely escaped from a nearby ornamental planting. I plan on taking a closer look on my walk tomorrow. 

Links to pictures of the specimen:Image 1,Image 2,Image 3

Since I did not see any prior Baltimore area reports of the plant on either iNaturalist or EDDMapS, I wanted to make sure the listserve was made aware of this sighting just in case. 

Best wishes,

Kate Wagner.
