Native of Peru in the coldest places. Farsétia Peruviana, Spreng. 
Petals obcordate, twice the length of the calyx. Leaves and

Cult. As the species of this genus ripen seed in abundance, 
it is the best method of increasing them. They only require to 
be sown in the open border, but, however, young cuttings of the 
shrubby sorts planted under a hand-glass will root freely. Not 
worth cultivating except in botanic gardens.

Cult. These very ornamental plants thrive well in a dry 
soil; they are well adapted for ornamenting rock-work or 
the front of flower-borders, where they will flower nearly all 
the season ; they are readily increased by dividing the plants at 
the root, or cuttings planted under a hand-glass will root readily ; 
seeds also ripen frequently, by which they may be raised in 
plenty.
