The thick rhizomes of this perennial spread over time to form large colonies in water. The tall spikes of lavender-blue flowers last from summer through fall and attract many pollinators. While pickerelweed prefers to be in water up to 12 inches deep in full sun and rich, loamy soils, it can tolerate part sun, poor soils, and occasional flooding up to 20 inches. This plant is resistant to browsing by deer and is tolerant of heat.
