[MAIPC] Five-fingered Aralia Spotted in Baltimore City

[Rod Simmons]

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<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.google.com%2Fmaps%2F%4042.3534645%2C-71.0708241%2C2a%2C69.4y%2C90.01h%2C63.14t%2Fdata%3D!3m6!1e1!3m4!1sIXxJ5CXSS8kvknq9aO1iEQ!2e0!7i13312!8i6656%3Fhl%3Den%26authuser%3D0&data=02%7C01%7Crod.simmons%40alexandriava.gov%7C4508f000e60a4043dbd208d5f7e04f17%7Cfeaa9b3143754aeeadccc76ad32a890b%7C0%7C1%7C636687465129231074&sdata=kp254wi8fy1KXOOn53i5imXRsz7m2BMAhBiLLTd5Uzo%3D&reserved=0>!

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 that I've spotted a developing stand of Five-fingered Aralia <https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.eddmaps.org%2Fmidatlantic%2Fdistribution%2Fcounty.cfm%3Fsub%3D57528%26id%3Dus_md_24510&data=02%7C01%7CRobert.Servis%40montgomeryparks.org%7C6a2bb1dbe92a464b19cb08d5f7c4f924%7Ca9061e0c24ca4c1cbeff039bb8c05816%7C0%7C1%7C636687347737295389&sdata=3smdqlgkqrBqPZ6d6jYpgx%2B%2FpssOm7EKc43zcvpS0NE%3D&reserved=0> (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. <https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.eddmaps.org%2Fdistribution%2Frecord.cfm%3Fid%3D7638330&data=02%7C01%7CRobert.Servis%40montgomeryparks.org%7C6a2bb1dbe92a464b19cb08d5f7c4f924%7Ca9061e0c24ca4c1cbeff039bb8c05816%7C0%7C1%7C636687347737305394&sdata=3%2FZ7xANprP4znoJJQpt%2BEydCl1OVJXY68zpq0gpMTfo%3D&reserved=0>  This is the first verified sighting of the plant in Maryland in EDDMapS since May 2016<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.eddmaps.org%2Fmidatlantic%2Fdistribution%2Fusstate.cfm%3Fsub%3D57528&data=02%7C01%7CRobert.Servis%40montgomeryparks.org%7C6a2bb1dbe92a464b19cb08d5f7c4f924%7Ca9061e0c24ca4c1cbeff039bb8c05816%7C0%7C1%7C636687347737305394&sdata=7WJwIG%2Fmi4wnHlqPV6vPjkTmQRK2XaCe3rFyuphzyFc%3D&reserved=0>, 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.

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.
