Onoclea sensibilis (Fr: Onoclée sensible | En: Sensitive fern)
Onoclea sensibilis, commonly known as Sensitive Fern, is a native fern species to North America. It's a large, graceful fern with delicate, feathery fronds that provide a tropical feel to the garden. This fern is perfect for adding texture and interest to shady areas in the landscape.

Sun Requirements: This fern requires partial to full shade to thrive. Direct sun exposure can cause the delicate fronds to scorch.

Soil Requirements: This fern prefers rich, organic soils with a neutral to slightly acidic pH.
Height and Spread: Onoclea sensibilis can reach a height of 2-3 feet with a spread of 2-3 feet. It spreads by roots and forms large colonies over time, creating a dense mass of fronds in the landscape.
