Summary

Botrychium lanceolatum, commonly known as Lanceolate Grapefern, is a perennial herbaceous plant that resembles a fern and is native to a variety of habitats including moist coniferous forests, wet meadows, and tundra in subarctic and temperate regions of the Northern Hemisphere. It is particularly found in areas like Greenland, as well as parts of North America and Eurasia. The plant typically grows to a height of 4-12 inches (10-30 cm) and features two distinct parts: a sterile frond that is lance-shaped and a fertile frond that bears spores.

Lanceolate Grapefern is appreciated for its delicate appearance and is often used in shaded or woodland gardens. It thrives in moist, well-drained soils with high organic content and prefers partial to full shade. While not widely cultivated, it can be a unique addition to native plant gardens or naturalized areas. This species is not known for significant problems with diseases or pests, but it requires a specific habitat to grow well, which can be a challenge in cultivation.CC BY-SA 4.0
