Talk:Rubus leucodermis

Dear MPF, in the Navajo and Tlavic few forests the whitebark or western raspberry generally is known as blue raspberry or frambuesa azul, as well in the heights of Utah. Black raspberries are Rubus occidentalis, very similar but not with the blue dust on their fruits. We asked also people fron L.A. suroundings: Blue raspberries. So this should be listed under "other commun names: Blue raspberry", do you agree? John Platino--Westbot 02:24, 25 January 2006 (UTC)
 * A google search reveals no hits for "Rubus leucodermis" "blue raspberry" other than a few wikipedia clones copying what had been put here, nor do a variety of textbooks list the name; I conclude there is no firm evidence for this usage, or if it is used, it is very rare (so not a common name). The linked British Columbia botanical atlas clearly lists "black raspberry" as a common name. - MPF 03:15, 12 February 2006 (UTC)
 * You might want to have a look at Blue Raspberry and Talk:Blue Raspberry; the treatment seems inconsistent with this article. Melchoir 06:15, 25 February 2006 (UTC)

As herb and other plant ingreedences applier for tribal traditional cures, I am in the forests from Oregon to Chiahuahua about 3 month a year. My spanish is better than written english, so please excuse and clear mistakes if they apear. Iam working with native curanderos/medicine men to find solutions where pharma does not work effective enough. The original blue raspberry fruit of Utah, California and Oregon whitebark raspberry(Rubus leucodermis, var. bernadinus) is an interesting cultivation project for medicine use in the mexican state of Morelos. Researchers from Ohio State University gave the reason for this activities for fighting against chronical inflamations like Arthritis and Rheuma. A patent registered at the USPTO at June 23, 2005 from Professor Gary Stoner(also Ohio State University) even promises to cure certain tumors and cancers with raspberries: http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PG01&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.html&r=1&f=G&l=50&s1=%2220050136141%22.PGNR.&OS=DN/20050136141&RS=DN/20050136141 --Westbot 22:54, 7 April 2006 (UTC)
 * Yeah, but that patent doesn't mention blue raspberries - only black. - MPF 18:16, 19 August 2007 (UTC)
 * No, mentions raspberries in general, explaining-the darker the fruit, the healthier! Rod Rod (Rodriguez)189.138.85.207 23:38, 3 September 2007 (UTC)

The natural blue raspberry and its flavors were reinvented when there was no access to fresh fruits from the west coast. The now everywhere used "Blue raspberry flavor" did not come from a mad man's brain- it was obtained from Rubus leucodermis var.bernardinus, which by no means is a "Black Raspberry" or a "Black Cup" but a blue one (Black Raspberries are Rubus occidentalis). Go out to the woods and look yourself as we american indigenous people do since long before wiki or the war.--Quer 01:07, 21 June 2007 (UTC)
 * Maybe, but we can't cite "the woods" as a reference for wikipedia! I am still finding no authoritative citation of "blue raspberry" for Rubus leucodermis. - MPF 18:16, 19 August 2007 (UTC)

I wonder that Indian American traditional * BLUE RASPBERRY * is just wiped out and away because some european explorers gave our fruits new names. Only a colorblind foreighner could see a *Blackcap* or black raspberry in our clear to dark blue friuts. In the tasts of us native common people blue raspberry and its flavors are everyday present from Canada to Arizona.Drinking Bear (talk) 08:24, 28 November 2007 (UTC)

No berry photo! And Oregon Raspberry?
It is pretty sad that as this plant has an edible berry, there is no photo of the leucodermis black raspberry. The German page does have a nice photo, although the leucodermis is called there, "Oregon Raspberry" so I am not completely without doubt these are the same thing. See: https://upload.wikimedia.org/wikipedia/commons/9/9a/7.4.09_Market_%283687763466%29.jpg DouglasHeld (talk) 22:26, 15 July 2017 (UTC)
 * The problem has been that there isn't a pleasant image of berries for Rubus leucodermis (specifically, wild white skin raspberry) in Wikimedia Commons; see here. The cultivated black raspberry (commercially grown in OR and WA states), Rubus occidentalis, here at Commons, bottom, has better pictures, and is probably the subject of the German image, but that isn't the species needed. Not much we can do until a Commons image is uploaded for R. leucodermis.--Zefr (talk) 23:04, 15 July 2017 (UTC)
 * And there is also no image of the chalky gray stems, a color VERY distinctive. GeeBee60 (talk) 06:36, 1 August 2017 (UTC)

No relationship to blue raspberry flavor or color
This edit removing reference to a blue raspberry applies because the supposed use of juice from R. leucodermis fruit for flavoring and coloring foods, such as in the image, is an urban myth, explained partly here. Blue raspberry flavor - and the blue color used to manufacture the liqueur, Blue Curaçao - derive from a common, synthetic, food-grade organic compound called Blue 1.

R. leucodermis is not commercially cultivated to any extent sufficient for making juice concentrates or commercial flavors, its juice is a dark purple (not sky blue, as in the image), and its flavor is too tart (without sweeteners) to be used in ice cones, ice cream, or other confections. There is no WP:RS source to support that this fruit is used for commercial raspberry flavors or blue raspberry colors. Zefr (talk) 02:22, 8 April 2022 (UTC)
