ornamental. Other beautiful hardy shrubs are our native Phila- 

 delphus, Potentilla, Hypericum, Rose Acacia, Elderberry, Indigo 

 shrub, Ampelopsis, Bitter-sweet, and many others that I might 

 name that are perfectly hardy. 



But I have already taken up too much time, and will now give 

 you a general list of the hardy ones. I shall begin with the 

 Clematis ; as there are so man}' varieties of these, I shall confine 

 myself chiefly to the species. 



Clematis Virginiana, flowers white, climber ; C. Pitchei-i, dark 

 purple, all summev ; C crispa, pale blue, fragrant ; C. verticilla- 

 ris, large, pale purple flowers ; C. vitalba, England's " traveller's 

 joy," white ; C. fusca and the variety violacea, blue, not showj' ; C. 

 gjxiveolens, flowers yellow, late autumn, seed-pods very showy ; C. 

 Davidiana, fine porcelain blue flowers, like miniature hyacinths, 

 and fragrant ; C. robusta, flowers white, September, one of the 

 finest of the late-blooming species. The varieties of C, Jackmanni 

 and the other garden varieties are too well known for me to speak 

 of here. 



Xanthorrhiza apiifoUa is a beautiful low shrub, with chocolate- 

 colored flowers, and fine autumn foliage. 



Most of the varieties of Poeonia Moutan are hard}', with fine, 

 showy flowers. 



The Allspice bush, Calycanthus Jloridus, and C. loevigatus; and 

 Schizandra Chinensis, a flne climber from China and Japan, with 

 fragrant flowers and scarlet fruit, are all desirable for their 

 fragrance. 



Of the Moon-seed we have three species, — Menispermum Cana- 

 derise, Daitricum, and Japonicum; they are good plants for cover- 

 ing small posts or arbors, the foliage being of a rich green. 



The Akebia^quinata is also a good vine for rock-work or trellises. 



Of the species of Berberis, the best are B. Canadensis, a native ; 

 B. vulgaris and its varieties, with j'ellow, red, purple, and white 

 fruit, and the variety with purple foliage. B. Thimbergi, a fine 

 low-growing species from Japan, is one of the best of all the 

 species in fruit, being brilliant all winter. Berberis Sieboldii, 

 known in the gardens as B. Hakodaki, is also a good shrub. 



Iberis coriacea and Alyssum gemonense are dwarf shrubs with 

 white and yellow flowers. 



Hudsonia tomentosa and H. ericoides, two native plants, when 

 once established will grow in the most exposed place and the poor- 

 est soils ; flowers yellow, in June.
