Is lesser spearwort good for wildlife?
Yes. It is on the RHS Plants for Pollinators list and the RHS suggests it for wildlife gardens.
Where to plant it
- Boggy ground or a pond shelf up to about 20 cm deep
- Small wildlife ponds, as it is less vigorous than greater spearwort
- Still or slow-moving water in full sun
Is it poisonous?
Yes. It is harmful if eaten by people or pets, and the sap can irritate and blister skin, so wear gloves when handling it.
How to plant and care for it
Plant in spring. The creeping stems root where they touch wet ground, so trim them back if it spreads too far.
