The Hypericum. 



The St. Johns-worts are well-known plants, with 

 yellow flowers ; some worthy of garden culture, and 

 others mere weeds. 



One species, however, is a very showy and desir- 

 able plant : — 



Hypericum calycinum 



Is a native of Ireland, Scotland, and other parts 

 of Europe, and proves perfectly hardy with us, if 

 slightly protected during the winter. The foliage is 

 large, evergreen, and thickly covered with pellucid 

 dots ; the flowers are large, yellow, and very showy, 

 two or three inches in diameter, with reddish 

 anthers. It is a low-growing shrub, thriving under 

 the drip of trees, and well-calculated for banks, rock- 

 works, or the margins of shrubberies. The roots 

 are creeping, and a small plant will soon cover a 

 large space. 



Our plants are on the borders of a Rhododendron- 

 bed, and are protected in winter by a slight covering 

 of pine-needles. We do not regard this as necessary, 

 for plants have done well wholly unprotected ; but 

 the foliage is vei;y much browned and the beauty of 

 the plant impaired.
