Arahis alpina. White Alyssum. (Europe, North America). — Height 6 inches. 

 Somewliat like the last, but with smaller flowers. This is very subject to attacks from 

 the flea bettle, which destroys the leaves and buds. 



* Adonis vernalis, Ox-eye. (Europe). — Height 6 to 9 inches. In bloom first week 

 of May. Flowers large, lemon-yellow, borne singly on the ends of the stems. A very 

 beautiful early flowering perennial. 



Yinca minor. Periwinkle. (Europe). — Height 6 to 9 inches. Begins to bloom first 

 week of May. Flowers a charming shade of bright blue. This pretty evergreen 

 perennial succeeds well in shady places. The prostrate stems take root and it spreads 

 rapidly. 



Saxifraga (Megasea) cordifolia. (Siberia). — Height 1 foot. Blooms in first week 

 of May. Flowers bright pink in a close panicle and on a heavy stem. This is an 

 attractive plant with large shiny, evergreen foliage. Looks better in a clump than 

 grown as a single plant. «S'. Schmidti is also good. 



Viola odorata. English Violet (Europe, Great Britain). — Although not perfectly 

 hardy, the single sweet scented or English violet can be grown successfully with a little 

 care. It should be planted in a partially shady place, preferably with a Northern 

 exposure and protected in winter with evergreen boughs, which should be gradually 

 removed in the spring in order to give the plants a chance to liarden off. The double 

 varieties are tenderer, but one known as Hardy Ptussian appears to be hardier than 

 other double kinds. 



* Mertensia virginica. Virginian Cowslip. (Western Ontario, United States). — 

 Height 12 to 18 inches. Blooms early in May. Flowers delicate gentian blue, chang- 

 ing to pink, and borne in long pendulous cymes. Leaves of an attractive shade of green.

 as Wisconsin.

 species in early spring. 



Pulmonaria mollis (maculata). Lungwort. (Siberia). — Height 1 foot. In bloom 

 first week of May. This is closely related to Mertensia virginica. Flowers blue and 

 borne in graceful racemes. The leaves are mottled, wliich give this plant a very striking 

 appearance. 



* Pholx suhulata Moss Eink. (Western Ontario, Eastern States). — Begins to 

 bloom in second week of May. There are many varieties of this charming little plant, 

 the flowers of which vary in colour from white to deep pink and are produced in great
