the sun's rays. So treated it grows vigorously and flowers 
beautifully in May and June, and will come up again in the 
same place year after year from its self-sown seeds. But if 
exposed to too bright a sun, and to dryness, it loses its 
vigorous habit, and becomes a poor dwindling thing not 
worth cultivation. 
It will also strike out freely from cuttings.
