Growing Giant Arrowhead — Care at a Glance

Light

Giant arrowhead performs best in full sun to part shade. Full sun produces the strongest, most upright growth and the most prolific flowering. In partial shade, the plant will still grow vigorously but may produce fewer flower spikes.

Water & Planting Depth

Plant giant arrowhead in a 2-gallon or larger submerged container set so that up to 6 inches of water covers the pot. It thrives planted directly at the pond margin in consistently moist to wet soil as well. Young plants begin with submerged ribbon-like leaves before transitioning to the bold emergent arrowhead foliage as they establish. For best results, plant in rich loamy soil in a container and lower into the pond at the appropriate depth.

Hardiness & Overwintering

Giant arrowhead is hardy in USDA Zones 7–11. In Zones 7–8, bring containers indoors before the first frost and overwinter in a cool greenhouse or bright indoor space with consistent moisture. In Zones 6 and colder, treat as a seasonal tropical — enjoy through the growing season and replace each spring, or collect seeds in fall for sowing after last frost the following year. In Zones 9–11, plants can remain in the pond year-round.

Spread & Maintenance

Giant arrowhead spreads via rhizomes and produces prolific seed. In managed water gardens, plant in a container to control rhizome spread. Deadhead spent flower stalks before seed sets if you want to limit self-propagation. Division every 2–3 years in early spring keeps plants vigorous. No serious pest or disease problems to manage.

A Note on Invasive Status

Sagittaria montevidensis is considered an invasive weed in Australia, where it shades waterways and outcompetes native aquatic plants. If you are located outside of North or South America, please check your local regulations before purchasing. Within its native range in the United States, it is a non-invasive native species and an ecological asset in wetland and pond environments.
