Loureiro's Crawfurdia. Shrub climbing. 



Cult. Crawfurdia is a genus of very showy, twining plants. 

 They will grow very well in a mixture of loam, sand, and peat ; 

 and may either be increased by cuttings or seeds. Should the 

 seeds of any of the species ever be introduced to our gardens, 

 we would recommend their being reared on a hot bed in spring, 

 and in the middle of May the plants so reared to be trans- 

 planted out in the open border, against a south wall, and other- 

 wise treated as the hardy species of Convolvulus.
