Understanding Pontederia Cordata

Pontederia cordata gets its name from Giulio Pontedera, an 18th-century Italian botanist. The species epithet ‘cordata’ refers to its distinctive heart-shaped leaves. This herbaceous perennial thrives in temperate climates. It is especially well-suited for growing in shallow water or moist soil. Many gardeners know this plant as Pickerelweed. It quickly establishes itself, offering a natural look to pond edges.

Distinctive Blooms and Lush Foliage

The flowering period for Pontederia cordata typically extends from July through to September. During this time, the plant produces tall, showy spikes of dense, vibrant blue-purple flowers. These flowers stand proudly above the water’s surface. Each spike is covered with numerous small, tubular blooms. This creates a striking visual effect. Below the blooms, the plant forms a dense clump of glossy, bright green leaves. These leaves are characteristically heart-shaped and provide an appealing texture. The lush foliage remains attractive even when the plant is not in flower, adding continuous interest.

Perfect for UK Water Gardens

Pontederia cordata is an ideal plant for various water garden settings across the UK. It naturally softens the transition between water and land. You can plant it directly into pond margins or in aquatic baskets submerged in shallow water. Its upright growth habit creates vertical interest. Furthermore, this plant provides valuable habitat and food for wildlife. Bees and butterflies are particularly fond of its nectar-rich flowers. The dense root system also helps to stabilise pond edges. Pickerelweed does not require regular pruning. You simply remove spent flower stalks and yellowed leaves to maintain its tidy appearance. This keeps the plant looking its best.
