The toilet paper plant! That was probably my earliest memory of Thimbleberry. Long before the appreciation of its jammy fruit punch flavored berry it was the go-to plant for when I found myself in a ‘number 2’ camping pinch.  Still as the years progress I continue to be surprised by the practical versatility of this widespread shrub.


Did you know…

Thimbleberry’s real name is Rubus parviflorus. It is in the Rosaceae (Rose) family and is in the same genus (Rubus) as raspberry, blackberry, loganberry, boysenberry, tayberry, dewberry and many others. Rubus fruit are an aggregate fruit composed of small, individual drupes, each individual is termed a drupelet. In a sense they are many little berries grouped together to make one large berry.

The Nuu-chah-nulth (New·chan·lulth) were known to collect the young shoots to be eaten raw as a vegetable and the berries were dried smoked with clams. The Kwakwaka’wakw (Kwak·wak·ya·wak) harvested the berries while they were still pink and hard, then stored them in cedar bags until ripe. The broad soft leaves can be used to make a quick pouch for holding the berries and provide a practical solution to assist you during your bathroom duties. Thimbleberry is both low in fat and calories and is a great source of vitamins A and C with traces of  Potassium, Calcium and Iron.

Medicinally

The young shoots, roots and leaves have been used to treat many ailments. A tea is made of the leaves or roots as a blood tonic in the treatment of nausea, vomiting, diarrhea and dysentery. Its effects are believed to tone and strengthen the stomach helping increase appetite. Rich in vitamin C, Thimbleberry helps boost your immune system and was used to ward off scurvy. A poultice of the dried powdered leaves treats wounds and burns and the fresh leaves can be crushed and applied to treat acne. A decoction of the roots has also been taken to treat acne.

  1. Awesome info and photos. I’m interested in using one of your photos for an upcoming (non-profit, educational) project, with appropriate credit, of course. It’s hard to find good photos of thimbleberry shoots! Can you contact me?

  2. Hi Henry,

    I was up camping in between Fish Lake and Clear Lake Resort this last weekend when I saw the craziest thing. Black, or dark purple Thimble berries. I am fairly confident in my plant identification most of the time, but I didn’t touch it because I had never sen it that way before. Have you seen what I’m talking about? do you know what it was? I have searched the internet far and near and all I come up with is wild black raspberries, but the leaves and fruits were the same as thimble berries. Please clue me in if you can 🙂

    Thanks
    Suzy
