Trying to identify this mystery plant in my yard... #749823

Asked May 13, 2021, 6:49 PM EDT

I recently noticed this thriving plant in my yard--not one that I recall planting--and before I assume it's an interloper and take it out, I thought you might be able to tell me what it is.  

Many thanks.

Hydrophyllum virginianum, commonly called Virginia waterleaf, is an upright perennial of the waterleaf family that grows to 12-24” tall. It is native to moist to wet woods from Quebec to Manitoba south to Oklahoma, Tennessee and North Carolina. In Missouri, it is typically found in low woods, thickets, ravine bottoms, bluff bases, river flood plains and stream valleys (Steyermark).

Tiny, white to lilac, bell-shaped flowers (1/3” long) bloom from May to June (sometimes with infrequent additional bloom to August) in rounded clusters (terminal cymes to 2” across containing 8-20 flowers) atop long stalks extending from the upper leaf axils beyond the leaves. Flower petals are fused into a tiny bell, with the hairy, white-filamented stamens emerging from and extending well beyond the rim of the bell.

Long-stalked lower leaves (6-10” long) are deeply divided into 5 to 7 sharply and coarsely toothed green leaflets (deep lobes) which are usually mottled with blotches resembling watermarks. Leaflets on the upper leaves are not as deeply cut.

Root tea was once used as an astringent to stop bleeding and for diarrhea and dysentery. Roots have been used as a mild emetic to cause vomiting. Tea or mashed roots were once used to treat cracked lips and mouth sores.

Genus name comes from the Greek words hydor meaning water and phyllon meaning leaf in reference to markings on plant leaves which give the appearance of being water spots.

Specific epithet is in reference to Virginia being part of the native territory for this plant.

Common name of waterleaf is in reference to the whitish leaf spots which resemble water stains.

Additional common names for this plant include John’s cabbage and Shawnee salad, both of which are in reference to the young leaves and shoots which are edible and may be added to salads.

Very interesting, thanks!  Apparently it is also found in Oregon, since I’m in the Portland, OR, metro area.  My yard is quite shaded (towering 160 foot Douglas fir trees, rhododendrons, azaleas, hostas), and this plant clearly doesn’t mind not having full sun.  I’ll keep an eye on it so that it doesn’t overrun things, however.

 

Maybe I’ll brew a little tea to just for a taste, too.

 

I appreciate your help.
