I always forget how fragrant is the shrub Brunfelsia until I walk past it in the Spring. It's common name is Yesterday Today & Tomorrow because the flowers start as purple yesterday, turn lavender today and pale to white tomorrow so you get all 3 colors at the same time. The plant comes in the regular size B. pauciflora 'Floribunda' which grows to 10 feet and B. 'Floribunda Compacta' which grows 3-4 feet. Both are widely available.
