Rubus Leucodermis
Known as the Blackcap Raspberry or Whitebark Raspberry, this Western North American native is a showstopper in the wild and a hidden gem for foragers. Its scientific name, leucodermis, literally translates to "white skin," referring to the striking, ghostly white coating that covers its arching stems. While it may look like a common blackberry at first glance, its flavor is uniquely complex—often described as a mix of traditional raspberry with a deep, wine-like richness.
The deep, concentrated pigment of the Blackcap Raspberry is so potent that it was historically used as a natural purple-blue dye for basketry and textiles. Even today, if you pick them with bare hands, your fingers will stay stained for hours!
To grow Rubus Leucodermis plant, commonly known as whitebark raspberry, follow these steps:


To fertilize this plant, apply an all-purpose balanced fertilizer in early spring before new growth emerges. Use a slow-release granular fertilizer and apply it according to the package instructions. You can also use a liquid fertilizer diluted in water and applied to the soil around the base of the plant. Avoid applying fertilizer too close to the stem or foliage of the plant, as this can damage the leaves or stems. Water the plant thoroughly after fertilizing. Repeat the fertilization process once or twice more during the growing season, spaced out by several weeks.
Rubus Leucodermis plant prefers well-draining soil that is rich in organic matter and slightly acidic. A mixture of loam, sand, and peat moss can be used to create the optimum soil conditions for this plant. It is important to ensure that the soil is moist but not waterlogged, as well-draining soil will prevent the roots from becoming waterlogged and rotting. A layer of organic mulch can be added to the top of the soil to help retain moisture and suppress weed growth. Additionally, fertilization should be done sparingly, as too much fertilizer can lead to the plant becoming weak and susceptible to diseases.
To propagate this plant, begin by taking a cutting from a healthy and mature stem. Use a sharp and clean pair of pruning shears to cut the stem at a 45-degree angle. The cutting should be at least 6 inches long and should have a few leaves attached to it.
Next, prepare a pot with well-draining soil. You can use a mixture of potting soil and perlite or sand to create a lightweight and aerated soil. Make a hole in the soil and insert the cutting, pressing the soil around it gently to hold it in place.
Water the cutting thoroughly and cover it with a plastic bag or a propagation dome to create a humid environment. Keep the pot in a warm and bright location, but avoid direct sunlight.
Check the soil regularly and water the cutting when it feels dry to the touch. After a few weeks, you should start to see new growth emerging from the cutting. At this point, you can remove the plastic bag or dome and begin to acclimate the plant to normal conditions.
Once the plant has outgrown the pot, you can transplant it into a larger container or into the ground, depending on your growing conditions. With proper care, your new plant should continue to grow and thrive.
