Yellow coralroot (Corallorhiza trifida)

Yellow coralroot

Also known as: Coral-root orchid

Yellow coralroot (Corallorhiza trifida) is a most singular plant in that it has no leaves! Instead, it takes some of its nutrients from certain fungi. Its rather small and plain flowers are something of a surprise since this plant is actually an orchid. This in part explains why the plant is not grown ornamentally, in addition to the fact that its natural growing conditions are very hard to replicate.

Water: Yellow coralroot thrives in moderate moisture, resembling its woodland habitat with consistent humidity. It requires weekly watering to maintain health, preferring evenly moist soil without waterlogging, especially during the active growing season. Typically grown outdoors, it shows neither drought tolerance nor excessive moisture needs.

Fertilize: Fertilizing yellow coralroot promotes growth, using balanced nutrition fertilizers sparingly, ideally once at the season's start. Avoid over-fertilization to protect delicate symbiotic relationships. Mix according to product guidelines, with reduced needs post-flowering. Always adhere to label instructions to prevent root damage.

Pruning: Yellow coralroot is a unique orchid species from cooler areas, identifiable by its slender, leafless stems and vibrant yellow flowers. Pruning should occur in early to late spring, focusing on dead or damaged stems to encourage growth, while avoiding root disturbance.

Propagation: Yellow coralroot is an unusual orchid that depends on fungi for nutrients, affecting propagation. The primary method is division, requiring the presence of a fungal partner in the soil for successful growth, as traditional practices are less effective due to yellow coralroot’s lack of chlorophyll.
