Description, §c. S. hypericifolia has small hard stems, 
with numerous side branches, clothed with a dark green 
bark, and with numerous wedge-shaped leaves, like these 
of St. John’s wort, with glands in their substance, which 
give them the appearance of being punctured on the 
surface; whence the name. The flowers are white, in 
small sessile umbels, resembling those of the common 
hawthorn, but smaller ; and whence, probably, and from 
its being common in Italy, and flowering very early in 
the spring, the name which it once bore in the London 
gardens, of Italian May. The flowers are produced in ore abundance ; 
and, when the shrub is allowed space to expand on every side, it forms a 
very beautiful bush in the flowering season. In England, it was first cul- 
tivated by Parkinson in 1640 ; and that author and Miller say that it 
came originally from North America: but Sir James Edward Smith thinks 
it more likely to be a native of Italy, as he found the hedges full of it 
between Terni and Foligno. Dr. Hooker, also, thinks it most likely to be a 
European species ; though Pursh appears to have found it in a living state in 
dry swamps in Canada and New York. It forms handsome garden hedges, 
and will bear the shears, which were formerly applied to it, to shape it into 
artificial forms, when topiary work was fashionable in garden scenery. It is 
readily propagated by layers, or by detaching its suckers.
