It can be found in various habitats such as pond and lake margins, including regions like northern rivers, the Everglades, and Louisiana. This long-lived perennial plant forms clusters and colonies, growing up to 1-2 meters tall. Its smooth stems emerge above the water surface and branch out, with each stem bearing a leaf and a flower spike. The bright green leaves are lance-shaped or ovate, reaching lengths of up to 18cm, while the flower spikes are dense and erect, measuring about 15cm in length. The small tubular flowers are a deep blue color and bloom in late summer. The leaves of Pontederia cordata are light or yellowish green and cordate in shape, with dimensions of approximately 230mm in length and 70mm in width.

How to care for Pickerelweed

Difficulty

With its straightforward care requirements, Pickerelweed is a hassle-free plant that anyone can enjoy.

Water

Pickerelweed should be watered regularly, allowing the soil to dry out between waterings.

Soil

Pickerelweed is very sensitive to dry soil. To ensure your Pontederia is thriving and blooming, choose a potting soil that retains moisture. A good soil should still allow for adequate drainage and contain lots of organic matter. Coco coir or sphagnum moss are great soil additives that will help to retain moisture and provide your Pontederia with the nutrients it needs for healthy growth. Make sure to mix these soil additives into the potting soil before planting and water the soil thoroughly. By providing your Pickerelweed with a well-draining, moisture-retaining soil, you can help to maximize its growth and keep it blooming.

Lighting

Pickerelweed requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Pontederia is always in the right place to thrive.

Toxicity

The Pickerelweed should be repotted when it has doubled in size or annually, whichever comes first. Providing fresh potting soil with all the essential nutrients each year ensures the plant's well-being, eliminating the need for fertilizer. Remember, plants derive their energy from the sun and not fertilizer.
