Collinsias succeed iu most garden soils, but prefer those 

 a light character. The seeds should be sown in patches 

 in the open border at the beginning of April, and the seedlings thinned 

 out to about 4 inches apart. If desired for spring blooming, they 

 should be sown between August and October, and protected during the 

 winter by covering with hand-glasses. They also make good pot-plants 

 for conservatory or window decoration.
