Comfrey, Bocking #4 (Symphytum × uplandicum ‘Bocking 4’)

Bocking #4 comfrey is a vigorous, deep-rooted perennial known for its exceptional biomass production, nutrient accumulation, and value in regenerative garden systems. Selected in England for its high yield and resilience, this cultivar is especially useful in composting, mulching, and soil-building strategies. While less commonly used medicinally than wild comfrey, it remains a cornerstone plant for permaculture and homestead-scale fertility systems.

Key Characteristics

Dynamic accumulator for nutrient cycling
Bocking #4 develops a deep taproot that mines nutrients—especially potassium, calcium, and trace minerals—from subsoil layers. These nutrients are concentrated in its large leaves, which can be cut multiple times per season and used as a nutrient-rich mulch around fruit trees, vegetables, or perennial crops. This makes it a key plant for closed-loop fertility systems.

High biomass production for mulch and compost
This cultivar is known for producing abundant leafy growth, often allowing for 3–5 cuttings per growing season. The leaves break down quickly, making them ideal for “chop-and-drop” mulching, compost acceleration, or layering in sheet mulch systems. It is one of the most efficient plants for generating on-site organic matter.

Sterile, non-invasive clumping form
Unlike common comfrey, Bocking #4 is a sterile cultivar that does not set viable seed, reducing the risk of unwanted spread. It grows in a defined clump that gradually expands over time, making it easier to manage in intentional plantings such as orchard guilds or designated fertility patches.

Essential plant for orchard guilds and permaculture systems
Bocking #4 is widely used around fruit trees where it acts as a living mulch, nutrient pump, and pollinator-support plant. Its early-season flowers provide nectar for bees, while its large leaves shade soil and reduce moisture loss. It is especially valuable in food forests, silvopasture edges, and regenerative agriculture systems focused on soil building.

  • Native range: Hybrid of European species (cultivar developed in England)

  • Soil requirements: Medium to medium-wet
  • Mature height: 2–4 feet
  • Bloom time: May – July

Highly recommend!
Color: yellow
Very pleased with this product. The bags are soft but still exfoliate well. They hold lather after wetting the outside, but then allow the soap to dry completely when hung by the drawstring. I will buy them again when I need them.

Nice addition
Color: yellow
These aren’t the most gentle but a good gentle exfoliation. They are thick enough to keep the soap in. Fits a normal bar soap easily. With the quantity included you’ll be able to share as you’ll not need many yourself since they hold up to washing very well. The color is a nice off white- natural looking.

All natural alternative to loofas
Color: yellow, Color: yellow
I love that they are all natural, plant based, and exfoliating. Mine is already starting to stink a little, so I’ve started making sure that I’m squeezing all the water and soap out after using and it doesn’t smell anymore lol. I prefer these over using loofa with microplastics. They are effective, strong, thick, and size is for small or regular sized soaps. If u have a bigger soap just use the soap first and then lather with this. You will still have to switch out every once in a while (like a loofa). Amazing value for price ⭐️
