Water forget-me-not (Myosotis scorpioides) is a perennial aquatic marginal plant known for its small, sky-blue flowers with yellow centers. It grows along pond edges, shallow streams, and other consistently wet areas.
Plant characteristics
- Scientific name: Myosotis scorpioides
- Plant type: Perennial marginal aquatic plant
- Flower color: Primarily blue with yellow centers
- Bloom time: Late spring through summer
- Height: Typically 6–12 in. (15–30 cm)
- Spread: Approximately 9–12 in. (23–30 cm)
- Sunlight: Full sun to partial shade
- Water depth: Shallow water, generally up to 3 in. (8 cm)
- Growth habit: Spreading stems and creeping roots that form dense colonies
Where to plant water forget-me-not
Water forget-me-not grows best in consistently moist soil or shallow water. Suitable locations include:
- Pond edges and shallow planting shelves
- Bog gardens and wetland planting areas
- Banks of slow-moving streams
Water forget-me-not is a rooted marginal plant rather than a true floating plant. Its roots should remain anchored in moist soil or an aquatic planting container.
How to care for water forget-me-not
- Sunlight: Provide full sun to partial shade.
- Water: Keep the soil consistently moist or submerged in shallow water.
- Pruning: Trim stems after flowering to maintain growth and appearance.
- Growth control: Remove excess growth to prevent overcrowding nearby plants.
- Propagation: Established plants can be divided in spring where cultivation is permitted.
Important planting considerations
Water forget-me-not spreads through creeping stems and seeds and may become invasive in certain regions.
Before planting, check local regulations and invasive plant restrictions. Do not introduce water forget-me-not into natural ponds, lakes, streams, or wetlands where it could spread into surrounding habitats.
Water forget-me-not can provide flowers and habitat for pollinating insects, but its potential to spread should be considered before adding it to a water garden.
