182 IIARDY SHEUBS. 



blossoms are yellow, spotted, produced in June : and if after flowering, the shoots 

 bearing the pods are clipped off, a second crop of blossoms often follows in 

 autumn. 



Caragana. — This genus belongs to the same natural order as the preceding. The 

 species are, with one exception, all yellow-flowered shrubs of rather low growth, 

 and are somewhat rare in gardens. They are all handsome, especially frutescens, 

 Chamlagu, Eedowslci, and spinosa, which are generally grafted on C. arborescens. 

 C. jubata has pink flowers. All of them flourish in sandy loam, and may be 

 increased by seeds or grafting. One species, C. Halodendron, will be referred to 

 under the head of Halimodendron. 



Clethra. — The C. alnifolia is found in most nurseries. It is a pretty shrub of 

 moderate growth, bearing white, Arbutus-like flowers in autumn, and requires 

 peat soil. There are several species all worth growing, one of which, Mexicana, 

 is an evergreen. 



Cratcegus. (Hawthorn.) — Some species of this beautiful and extensive genus 

 should be in every garden, and none are more beautiful than the numerous varieties 

 of the ft oxyacantha. Although most of the species grow naturally from ten to 

 twenty feet, or more, high, all of them may be grafted on low stems of the common 

 Hawthorn. The double scarlet-flowered and golden-berried varieties of oxyacantha, 

 with the species flava, odoratissima, and tanacetifolia, are among the best, and are 

 generally kept by nurserymen. 



Deutzia. — This genus is nearly allied to the Syringa, and comprises several very 

 desirable shrubs. Scabra, the earliest introduced, is now pretty well known, and 

 has taken a high rank. It produces an abundance of white fragrant flowers, and 

 small plants blossom freely. The other species are corymbosa, staminea, sanguinea, 

 and gracilis. Corymbosa we have never been able to flower, although we have tried 

 it in a variety of soils. Gracilis, the most recently introduced species, is a 

 charming little plant, and with D. scabra should be procured by everybody. Both 

 may be had very cheap and are quite hardy. They are increased by cuttings. 



Forsythia viridissima. — A very beautiful shrub, and valuable on account of its 

 early flowers. It is sometimes grown against a wall, but is hardy enough for a 

 standard in all but the most northern counties. The blossoms are large, of a 

 yellow tint, and copiously produced along the previous year's wood ; the shoots 

 should, therefore, never be shortened until after flowering. It will grow ten feet 

 high, but may be kept dwarfer by pruning. 



Gordonia.—hx warm situations, one or two species of this genus will succeed. 

 They belong to the Camellia tribe, and produce large white or yellow flowers; those 

 of lasianthus are of the latter tint ; pubescent, which is more common, has white 

 blossoms. Where a wall can be afforded them, they will do better than in the open 

 shrubbery.
