Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Maintain consistently moist soil, mimicking its native boggy conditions. Water thoroughly when the top inch of soil feels dry, but avoid waterlogging.
Reduce watering slightly during dormant periods, but never let the soil become completely dry. Good drainage is essential to prevent root rot.
Remove any dead, damaged, or yellowing leaves promptly to maintain plant health and appearance. In fall, after the foliage dies back, cut the stems down to about 2-3 inches above the soil line.
This encourages vigorous new growth in the spring.
Propagate through division of tubers in spring before new growth begins. Carefully separate the rhizomes, ensuring each piece has at least one eye or bud.
Plant these divisions in well-draining soil and keep them consistently moist until established.
Repot every 1-2 years in spring as needed, or when the plant becomes root-bound. Choose a pot that is slightly larger than the current one with good drainage holes.
Use a rich, well-draining potting mix amended with organic matter for optimal growth.
