BOLTONIA (FALSE CHAMOMILE) 



As single plants the Boltonias are not much for show. You must 

 see them growing in masses in order to appreciate them. In the 

 background of a perennial bed or planted along a fence, with a fore- 

 ground of smaller plants, they surely liven things up when covered 

 with their Daisy-shaped flowers. You can also use them cut for 

 decorative purposes, but 'before using them place the stems deep 

 in water for at least twenty-four hours in a cool, dark place; other- 

 wise, they soon wilt. They are propagated by division of the old 

 plants after they are through flowering and either planted where 

 they are to flower the foUowing year or given about 4 in. of space 

 in a frame to be transferred to their permanent quarters the follow- 

 ing Spring. There are two colors B. asteroides, white, and B. latis- 

 quama, light lavender.
