Garden notes 
Dennstaedtia punctilobula can survive very cold winters with annual averages as low as -40� Fahrenheit.  It needs a bit of a cold spell with temperatures below 15� Fahrenheit to do its best.  Eastern hay-scented fern (also known as cup fern and boulder fern) needs summer days with high heat.  The optimal soil texture for this plant is one that is loamy.  This species likes full sun to partial shade.  It does well in dry soils. |
