Crowded- flowered Phacelia. Fl. July, Oct. Clt. 1835. PI. 

 1 to \\ foot. 



Cult. Some of the species of Phacelia 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.
