Is marsh helleborine a pond plant?
It is a bog plant, not a water plant. Plant it with the crown at soil level in ground that stays damp all year, such as a bog garden or the wet bank beside a pond. Do not stand it in water.
Where to plant marsh helleborine
- Bog gardens and damp borders
- The wet bank of a wildlife pond
- Damp, chalky or lime-rich soil
How to plant and care for it
Plant in spring at the same depth as in the pot, and keep the soil moist at all times. It spreads slowly by rhizomes to form a colony, so avoid disturbing the roots once it is established.
Is it legal to grow a wild orchid?
Yes, when bought from a nursery. Never dig plants from the wild: it is illegal anywhere in the UK to uproot a wild plant without the landowner's permission, and marsh helleborine is specially protected in Northern Ireland.
