X FORSYTHIA INTERMEDIA var. PRIMULINA PRIMROSE FoRSYTHIA 



A variety worth consideration because of its fewer, paler flowers which are 

 borne in such a manner that its garden effect is somewhat less violent than 

 some of the more floriferous species and varieties. 



X FORSYTHIA INTERMEDIA var. SPEGTABILIS 



Showy Border Forsythia 

 This variety, with its numerous bright yellow, early spring flowers crowded 

 on upright stems, is perhaps the most eye-smiting of all the Forsythias and, 

 judged on this basis alone, can be considered the best. 



Forsythia ovata KOREAN FoRSYTHIA 



A slower-growing, hardier species of distinctly inferior garden value except 

 for its possible earlier flowering in those sections where other Forsythias are 

 hardy. However, it can be recommended for cold, inland areas where buds 

 of the more common species arid varieties blast during the winter. 



Forsythia suspensa var. Sieboldii WEEPING FORSYTHIA 



Pendulous or trailing-branched shrub suitable for covering banks or for 

 training up on walls as a vine. 



FOTHERGILLA GARDENI DWARF FOTHERGILLA 



Slow-growing, symmetrical, low, deciduous shrub which is covered in spring 

 with spikes of white flowers. For garden purposes it may be considered to 

 be a dwarf form of F. monticola. Suitable for the large rock garden. 



FOTHERGILLA MONTICOLA Alabama Fothergilla 



While considered by some to be indistinct from F. major, plants grown 

 under this name are of shorter stature, more spreading habit, and yield slightly 

 larger flower spikes. This inhabitant of peaty soils is slow of growth, regular 

 in outline, and in foliage aspect somewhat suggestive of the Witch-Hazel, to 

 which it is related. Its spikes of white flowers are borne on a framework of 

 stiff, gaunt branches in May, just as the leaves are beginning to unfold. In 

 autumn appears the brilliant crimson or yellow foliage color. For best effect 

 it should stand alone. 



Franklinia — See Gordonia 



Fraxinus amerlcana WHITE Ash 



A familiar, quick-growing, native, deciduous shrub of moist woodland, 

 which is prone to volunteer in shrub borders or other disturbed areas of soil. 

 Under wild conditions it can become a timber tree one hundred feet or more in 

 height. It is, however, of rather coarse texture for street or home-grounds 

 use, and is subject to attack by scale insects. 



Fringe-Tree — See Chionanthus 



GAULTHERIA PROCUMBENS Wintergreen 



A familiar plant which is native to woods and open lands, and has a definite 

 place in the wild garden or rockery. 



Gaylussacia baccata (G. rcsinosa) BLACK HUCKLEBERRY 



A twiggy, deciduous shrub up to three feet, which in nature is variable in
