Nyman's Cuckooflower

Nyman's cuckooflower should be watered regularly based on the soil's moisture content. During the growing season, keep the soil moderately moist but not soggy, and be sure to check before watering. Allow the top few inches of soil to dry before watering again. During the winter months when the plant is dormant, water less frequently, only watering when the soil is starting to dry out. Depending on temperatures and humidity levels, Nyman's cuckooflower may need occasional watering, about 1 - 2 times per month, to stay hydrated.

Nyman's Cuckooflower typically receives sun for most of the day during the summer months. It prefers full sun, but some morning shade is beneficial during the hottest parts of the day. In drier areas, it is best to give the plant midday or late day shade as it is sun-sensitive and can easily dry out and become stressed in extreme heat. During the winter months, Nyman's Cuckooflower benefits from at least 4 hours of sun. Whenever possible, provide indirect sunlight to protect the foliage during winter and to help it better grow and flourish.

Nyman's Cuckooflower (Cardamine polemonoides) should be pruned lightly in late spring or early summer, before unexpected frosts. This will promote the development of strong flowering shoots for the following year. The best time to prune this species of plant is when the blooming has finished, to ensure the plant is not exhausted from the growth of new buds. Pruning should be limited to removing dead, damaged or weak growth. Removing no more than 1 third of the stems is recommended.
