Thimbleberry (Rubus parviflorous) Questions

I bought a few Thimbleberry (Rubus parviflorous) plants and am planning to put them in a shady part of my yard near Chicago. I have a few questions.

Are they strong fruit producers?
Are they black walnut / Juglone tolerant?

Thimbleberry (Rubus parviflorous) are not popular on this forum so I am guessing they might suck as a cultivated plant?


They produce very little fruit
but what little you get is intense flavor.
Too bad it hasn’t been used in breeding.

Rubus is unaffected by juglone.


I think they are wonderful i just eat them in the wild.

They are an excellent shade loving ground cover plant

Agree with others that I enjoy them quite a bit when grazing/foraging on hikes/camping trips, but would only plant them if I had a bigger yard since they don’t produce much per plant.

They colonize (spread out) via underground runners. Plants in a sunny location seem to
set more fruit than plants in a shaded area.


I found a superior selection of Thimble Berry.
It may be a hybrid with another Rubus.
Will sure be watching it.
I got a rooted piece of it at home as well.image|690x920


Finally went back to see the ripe berries.
A great disappointment.
Nothing special .

But I found this variant of Rubus yesterday.
Unusual leaf type.
Anyone else know what it is?


Is that the ground directly underneath and are those slender runners?

Not a great find after all.

Yes it’s low on the ground
looks like Rubus Leucodermis, but different leaf type .

here’s a picture of the stem
pale blue and thin.

Compare to various dewberries. There may be 3- and 5-leaflet varieties.

How does this aid in identifying the plant in question?

Turns out that the Thimble berry was nothing special.
Oh well.
