Cult. Some of the species of Phacélia are pretty when in 
blossom. They all require a sheltered situation, and as they are 
apt to rot in the winter, the situation in which they are grown 
should also be dry. A few duplicate plants of each should be 
grown in pots, in order that they may be sheltered in winter. 
All are increased by seeds.
