Peltandra Undulata Aquatic Pond Plant – Wavy Arrow Arum

Peltandra undulata, commonly known as Wavy Arrow Arum or Wavy Arrowhead, is a perennial aquatic plant native to wetland habitats of North America. Here’s a detailed description and care guide for Peltandra undulata:

Description:
Peltandra undulata is a rhizomatous plant that grows in clumps and features attractive foliage. The leaves are large, arrowhead-shaped, and have wavy or undulated edges, giving the plant its common name. The leaves are typically green but can have varying shades of green, ranging from light green to dark green. The plant produces a flowering stalk that emerges from the center of the clump, bearing small, inconspicuous flowers. The flowers are followed by berry-like fruits that turn black when mature.

Care Guide:

Light: Peltandra undulata thrives in partial shade to full shade. It prefers filtered sunlight or dappled shade. Avoid placing it in direct, intense sunlight, as it can scorch the leaves. If grown indoors, place the plant near a window with bright, indirect light.

Water: As an aquatic plant, Peltandra undulata requires consistently moist soil. It thrives in wet or waterlogged conditions, such as the margins of ponds, bogs, or other water features. The soil should be kept consistently moist, but not waterlogged, to avoid root rot. Regular watering is necessary, especially during dry periods, to maintain the desired moisture level.

Soil: Peltandra undulata prefers rich, loamy soil that is high in organic matter. It can tolerate a range of soil types, including clay, but the soil should have good moisture retention. In aquatic settings, the plant can be grown directly in shallow water or in wet, boggy soil.

Temperature: Wavy Arrow Arum is hardy in USDA hardiness zones 5-9. It can tolerate a wide range of temperatures but prefers mild to cool climates. Protect the plant from extreme heat or cold, as prolonged exposure to such conditions can negatively impact its growth.

Fertilizer: Peltandra undulata typically doesn’t require heavy fertilization. However, you can incorporate a slow-release aquatic fertilizer or a general-purpose granular fertilizer into the soil during the growing season. Follow the package instructions for application rates. Avoid excessive fertilization, as it can lead to excessive foliage growth and reduced flowering.

Pruning: Pruning is generally not necessary for Peltandra undulata. However, you can remove any dead or yellowing leaves to maintain a tidy appearance. If the plant becomes too crowded, division can be done in early spring to propagate and rejuvenate the plant.

Pests and Diseases: Peltandra undulata is relatively resistant to pests and diseases. However, it can occasionally be susceptible to aphid infestations or fungal diseases, particularly in humid conditions. Monitor the plant regularly and take appropriate measures to control any pest or disease issues. Providing good air circulation and avoiding excessive moisture on the foliage can help prevent fungal problems.

Peltandra undulata, with its attractive wavy leaves and tolerance for wet conditions, makes a lovely addition to water gardens, pond margins, or other moist areas in the landscape. By providing the right growing conditions and regular care, you can enjoy the unique foliage and subtle beauty of this aquatic plant.
