white variety. Cassia Marylandica (American senna), 

 growing three to four feet high, is a native plant well

 with blue, very fragrant, solitary, nodding flowers one to 

 two inches across, and blooming in July and August. O. 

 recta (upright virgin's bower) is an old, well-known species, 

 two to four feet high, with numerous white summer
