GARDEN FLOWERS. II 



We know of but one species. The plant is perennial, but 

 succeeds best as an annual. 



A. viridiflora (green-flowered); tender perennial; 15 feet; 

 flowers green, fruit scarlet, all summer ; South America; 1860. 



ABRONIA. [Nyctaginaceae.] A very pretty genus of trail- 

 ing plants, which, though properly frame perennials, succeed 

 better with us treated as annuals. The flowers are in heads 

 like a verbena, and cover the plant. 



Soil, a sandy peat and leaf-mould, though the plants suc- 

 ceed in any good garden soil. Propagated by cuttings 

 rooted in sand in spring, from plants wintered in the green- 

 house ; or, better, by seeds sown in frame in May, and trans- 

 planted to the garden after the weather has become warm. 

 A. umbellata, with rosy-lilac flowers, is the best variety. 



A. mellifera (honey-bearing); flowers orange, from June to 

 August; California; 1826. A. pulchella (neat); flowers pink, 

 from July to September ; California; 1848. A. rosea (rose-col- 

 ored); flowers rosy-red, July to September; California; 1847. 

 A. umbellata (umbel-flowered); flowers rosy-lilac, all summer; 

 California ; 1825. All the varieties grow about six inches high. 



ACACIA. [Mimoseae.] The only hardy species of this 

 very extensive genus is A. Julibrissin, which succeeds well 

 south of New York, as a hardy shrub or small tree, in any 

 garden soil. Propagated by cuttings of year-old shoots, or 

 by seeds. 



A. Julibrissin (silk- tree) ; hardy tree; I a to 12 feet; flowers 

 pinkish-white, in August; Levant; 1745. 



ACACIA PSEUDO. See ROBINIA. 



ACACIA ROSE. See ROBINIA. 



ACACIA THREE-THORNED. See GLEDITSCHIA. 



ACAENA. [Sanguisgrbeae.] A family of not very showy 

 perennials, growing in common garden soil, and propagated 

 by seeds or division ; generally tender.
