SHRUBS THAT ARE PERFECTLY HARDY. 81 



the fruit is edible. The species and varieties are Asiatica, alnifo- 

 Ua, alpina, vulgaris, and Canadensis. In the Canadensis section 

 there are a number of well marked varieties. The variety oSfong'i- 

 folia has fine edible fruit ; the variety rotundifolia has round 

 leaves, and in the type the leaves are of a reddish color when first 

 opened. The species oligocarpa, from the White Mountains, is 

 the earliest of all. 



Photinia villosa is a dwarf shrub with flowers similar to those 

 of the hawthorn and scarlet fruit. 



Among the Hydrangeas we have a few species that might be 

 termed perfectly hardy ; there are radiata, arborescens, paniculata, 

 panicidata grandiflora, vestita, and vestita pubescens. The vestita 

 and its variety are the earliest to bloom, and are followed by 

 radiata, arborescens, panicidata, and paniculata grandiflora, so 

 that we can have them in bloom from June till September. The 

 climbing Hydrangea is a good addition to our hardy shrubs. 



Of the Deutzias, we have gracilis and parvijlora, the latter a 

 new species from Japan, with corymbs of white flowers, a few 

 days earlier than gracilis. 



In the Mock Oranges there are many varieties of good hardy 

 flowers. Some of them are Philadelphus latifoUus magnijicus, a 

 fine variety with large white flowers ; nivalis, pearly white ; 

 grandiflorus, a fine large late variety ; Zeyheri, a variety with 

 flowers not much larger than those of the deutzias ; Gordonianus, 

 a fine late American species ; microphyllus, a miniature species 

 from Colorado ; speciosus, a fine variety ; nivalis, a very pure 

 white ; Cohimbianus, a fine intermediate flowered variety ; and 

 magnificus coronarius and its varieties. Schrenkii is the earliest 

 of all the syriugas, and the grandiflora section is the latest. 



Jamesia Americana is a neat shrub from the Rocky Mountains, 

 growing from two to three feet in height, with white flowers. 



Another rare hardy plant is Fendlera rupicola, from Texas. 

 This is a low, small shrub. 



In the Currant famil}' we have many species that are hardy, but 

 a large proportion of these are only of botanical interest. Among 

 the best for ornamental purposes are Ribes floridum, a yellow 

 flowered variety with black fruit ; R. prostratum, a fine species 

 for rock-work or trailing on the ground ; R. aureum, the old Mis- 

 souri currant, and its vaviety, palmata ; also Gordonianum, which 

 seems to be a hybrid between sanguineum and aureum. The
