Panicled-flowered Vesicaria. Pl. 3 foot. 
Cult. The species of this genus are well adapted for orna- 
menting rock-work or the front of flower borders: young cut- 
tings planted under a hand-glass will soon strike root; but the 
best and most general method of increasing them is by seed, 
which ripen in abundance. They thrive best in a dry situation, 
in any kind of soil. Some of the rarer kinds should be planted 
in pots, so that they may be protected by a frame during severe 
weather.
