FLOWERING TREES AND SHRUBS 95 



growth and floriferousness being then much increased. 

 The foliage is neat and pea-green, while the bright- 

 pink flowers are produced in long racemes. It is a 

 pretty bush, and grows freely enough in any good garden 

 soil, but very fine flowering specimens may be seen in 

 light, sandy soil of a peaty nature. There is a white- 

 flowered variety named I. Gerardiana alba. I. atropurpurea 

 (Nepaul, 1816), with dark-purple and crimson flowers, is 

 only half-hardy. 



Itea (Saxifrageae). 



}* Itea vikginica. — North America, 1744. This is a neat, 

 deciduous shrub of 6 feet or 8 feet in height. The ovate- 

 lanceolate leaves are of a light greyish-green, turning 

 deep red in autumn, and 3 inches to 5 inches long, and 

 the small white flowers are produced in dense racemes in 

 June. Planted in a somewhat shady place, and in rather 

 cool, damp soil, this little shrub does well and flowers 

 profusely. 



Jamesia (Saxifrageae), 



Jamesia ameeicana. — Rocky Mountains and Colorado, 

 1865. Amongst early spring-flowering shrubs this pretty 

 but neglected plant is one of the best, of perfect hardihood, 

 for it stands the vigour of our winters with impunity, and 

 of dense thick growth ; it is suitable for using in a variety 

 of ways, as well as for purely ornamental purposes. The 

 leaves are oval and neatly dentated, and the flowers 

 individually of large size, pure white, and produced in 

 terminal bunches in June. Cool soil and a shady situa- 

 tion would seem to suit this shrub admirably, but for 

 screen purposes in the rock garden or border it is invalu- 

 able on account of the strong and dense twigs.
