Curly pondweed (Potamogeton crispus) is a perennial. It is hardy to USDA zone 4, or down to -30°F (-34°C). This plant likes full or part sun and moist, sandy or loamy soil. Its spread reaches about 35 to 59 inches, so give it plenty of room. It blooms in early to late spring, early to late summer, and early to late autumn.
Pairs well with Liverleaf, American smoketree, and Gladiator ornamental onion.
