Symphytum x uplandicum 'Bocking 14'
Bocking 14 is a sterile cultivar of Russian comfrey — it produces no viable seed, so it stays where you plant it. Each cutting will grow into a full plant and can be divided to produce more within a year or two.
We grow our comfrey in southeast Kansas and dig cuttings fresh for each order. These plants are adapted to real Midwest conditions — heat, wind, and inconsistent rainfall — not greenhouse production.
Cuttings ship as ~1" root sections, ready to plant on arrival. This is the standard propagation method for Bocking 14 and produces vigorous plants when planted correctly.
What it’s used for
Comfrey is best understood as a permanent fertility plant, not a one-time crop.
Once established, it can be cut multiple times per season and used to:
- Build soil with chop-and-drop mulch
- Accelerate compost
- Produce liquid fertilizer (comfrey tea)
- Supplement chicken feed (20–30% protein by dry weight)
- Support pollinators with reliable late-spring blooms
We primarily use it along orchard rows, where repeated cuttings feed the soil year after year — often alongside rabbit manure as part of a long-term fertility cycle.
Site: Full sun to partial shade. Adapts to most soil types. Prefers consistent moisture, especially in the first season.
Hardiness: Zones 3–9
Important: Comfrey is persistent once established. Small root fragments left in the soil will produce new plants the following year. Plant it where you want it long-term.
