My Sweet Olive plant was doing poorly. I only noticed it today because I could smell it walking by on my way to the front yard to do more rose pruning(& weeding). The fragrance is spectacular even if the tiny flowers are not. Funny common name given that the plant is not an Olive at all. Osmanthus fragrans is a tall growing shrub native to Asia. I think the flowers smell like apricots. An evergreen shrub or small tree it grows to about 10' tall in full sun or part shade. Slow to start I never plant them in one gallons. They'll just sit there too long. I always start with a five gallon size.
If you don't grow Osmanthus fragrans, you should!
