Purple flowering thimbleberry


I like to try various rubus plants. So I picked up rubus odoratus. Like summer bearing raspberries it fruits off of floricanes. This seems to be one that is hard to get a fruiting one. Many do not fruit. Also if you expect decent production you will be disappointed. Out of four plants only one had fruited. Aggressive grower that suckers.

Taste is unique. Not sure I love it? I need to taste more. Rather late in the year and most of the fruit is not ripe yet. What’s great is it is in full shade and fruited. Wine berry will too. This species is endangered in Illinois and Indiana.

mine finally fruited this year. its a pretty small berry but i agree it has a unique taste. but man does it spread! don’t know if ill keep it as its a scant producer. came from oikios.

I put some at my cottage and at home I’m removing the ones at home. Takes up a lot of room and spreads. I don’t care up at the cottage if it spreads. It seems adding more made them all fruit. I noticed ones I bought years ago and never fruited have fruit now. Maybe the addition of new plants help spread the pollen around? Or they needed time?

R. odoratus is commonly called Purple Flowering Raspberry.
R. parviflorus is commonly called thimbleberry.

But of course your images look just like thimbleberry, so your description is fine.

I have had bad luck with the white flowered thimbleberry. Also had a raspberry/thimbleberry cross that died. I have tried a few times to establish a plant with no luck.

I have some f this but have always seen it referred to as an ornamental raspberry. It is pretty, but the fruit are small and tasteless. It is hardy so it works for along my sidewalk.

Yes that makes sense. Why I mentioned the genus species as common names vary by region. Rubus are raspberries and blackberries. many don’t know that hundreds of other species exist. I would love to get the Korean black raspberry. It is a different species than the native black raspberry. I have not found any for sale in this country.

Do you know the scientific name? There may be specimens in USDA ARS GRIN at the site in Oregon.

Rubus coreanus Miquel

Looks like there are several accessions in USDA ARS GRIN seed accessions. One is from Japan, the rest say they are from china and korea. Click on the passport data for more information. Good luck!

PI 553172 GRIN-Global (Japan, Original wild Korean seedlot)

PI 606456 GRIN-Global (China)

PI 618363 GRIN-Global (S. Korea, Fruit bright yellow, medium firmness, 14-16 mm x 8-9 mm. Very good taste, unique flavor 11 deg brix.)

Fascinating genetic diversity in this species! Purple, yellow, and orange fruits!

Hello, I am new on this forum. I am wondering if anyone has any of the pink thimbleberry that Oikos used to sell. And if so, has anyone had any luck with getting fruit from it?

Hi Austin, welcome to the forum!
Your question will get a wider audience if you post a new thread in the General Fruit Growing category.

Yes I have fruited those plants. They grow quite aggressively here. The fist wave of flowers usually don’t produce fruit. But as the plants gets into the summer the flowers do bear fruit. It is rather small and very bland flavor. I no longer harvest the fruit. I do like the plant in my woods edge garden. The leaves are attractive.

Thanks for the response Drew51. Do you know of anyone beside Oikos who sells these or is interested in selling some to me? Oikos is sold out.

I just happen to acquire a thornless Rubus coreanus cultivar (R. coreanus var. ‘jeonwon’)
I need time to evaluate though.
Here is the picture provided by the seller

I live in Korea and sadly a cultivated Rubus coreanus is virtually extinct because it doesn’t make sense commercial wise.
Farmers here stopped cultivating Rubus coreanus long ago and have been growing Black raspberries instead.

My goal with R. coreanus is to cross it with R. idaeus to incorporate primocane fruiting genes to R.coreanus.
