ON THIS PLANT

Platanthera hyperborea, the northern green orchid, is small orchid found only in Greenland, Iceland, and Akimiski Island in Canada. Numerous authors cite the species as widespread in other parts of Canada and also in the United States; such populations are more correctly referred to as Platanthera aquilonis.

A note from PlantMom

The Northern green orchid typically has strong resistance to disease and is affected by relatively few insect pests. Its care is considered difficult because it requires a high-humidity yet well-ventilated environment with minimal harmful pathogens. Overwatering can cause root rot. Anyone can grow a Northern green orchid, but keeping it healthy and getting it to flower again demands more growing experience.

CARE GUIDE

How to keep Platanthera Hyperborea.

Light

Northern green orchid is native to habitats such as forest understories or rocky areas, where it grows in natural shade. It prefers partial sun but can also tolerate full sun or full shade, showing its adaptable and hardy nature.

Water

The Northern green orchid thrives with adequate moisture, but it can tolerate some drought conditions. During the summer, water the plant weekly, and in the fall and winter, water every 10 days. To maintain humidity, mist the plant, particularly during dry weather. Use water with a neutral pH, and consider neutralizing tap or rainwater before use.

Fertilizer

For the Northern green orchid, the best time to fertilize is early spring, when the flowers are starting to form. The proper fertilizer promotes better blooms and helps the Northern green orchid produce attractive flowers. Fertilizing in early spring ensures good flowers during the season and supplies energy for its dormant growth phases.

Pruning

The Northern Green Orchid is a hardy perennial that benefits from careful pruning in early spring, just before new growth begins. To encourage blooming, remove dead foliage and spent flower spikes, taking care not to cut into healthy tissue. Regular pruning enhances airflow, reduces the risk of disease, and promotes vigorous growth, resulting in a healthier plant.
