The Hardy Lace Fern 

 Polystichum Angulare 



With careful protection, covering with a 

 liberal amount of leaves in the winter, this 

 graceful variety illustrated at the top of 

 this page will prove hardy as far north as 

 Philadelphia. The fronds are from 18 to 24 

 inches long by 2| to 3 inches wide with finely 

 divided pinnae of a rich dark green color with 

 darker midrib and stem. 75 cts. each. 



Choice Hardy Ferns 



Suitable positions for Hardy Ferns are to be 

 found in almost every garden. With few 

 exceptions they do best in a shady or semi- 

 shady position in rich well-drained soil where 

 they can be liberally supplied with water 

 during dry weather. Where the soil is stiff 

 or clayey, incorporate a liberal quantity of 

 leaf-mould, peat or other loose material to 

 make it friable. 



We give after each variety the average height
