Growing notes
- Forage plant for bees and hoverflies in spring
- Sheets of bluebells in deciduous woodland in April and May are an internationally recognised UK habitat
- Distinguish from invasive Spanish bluebell (H. hispanica) — English bluebells have one-sided flower spikes that arch over, white pollen and a strong scent
- Buy in the green from reputable suppliers — never dig from the wild
Pet caution: English bluebell is listed as potentially harmful to cats and/or dogs. Keep pets from grazing on it, and contact a vet if you suspect your animal has eaten some.
