Growing notes
- Critical early spring forage for emerging queen bumblebees — flowers in March when little else is open
- Looks like stinging nettle but does not sting (no relation — different family)
- Edible young shoots — mild flavour, traditional spring pot herb
- Spreads by underground stems — useful ground cover under hedges and shrubs
