Webb's Water Gardens Canna Longwood

These are marginal plants, meaning they prefer shallow water. Place them in depths ranging from 0 to 6 inches of water, or keep the soil consistently moist in a bog garden setting.

Canna Longwood is a tropical plant and is not frost-hardy. In colder climates, you will need to lift the rhizomes in the fall and store them in a cool, dry place indoors until spring.

Yes, these are heavy feeders. For the best bloom production, use an aquatic plant fertilizer tablet pushed into the soil once a month during the active growing season.

These plants can grow up to 72 inches tall and have a substantial spread. Give them enough room in your pond or bog garden so they don't crowd out smaller, slower-growing aquatic plants.

While they can tolerate partial shade, they perform best and produce the most vibrant blooms in full sun. If placed in too much shade, you will likely see lush foliage but fewer flowers.

Plant the rhizomes in a sturdy aquatic planting basket using heavy garden soil or specialized aquatic potting media. Ensure the rhizome is covered with an inch or two of soil, leaving the growing tip exposed if possible.
