Anne: Since Mock Orange are known for their fragrance and plant breeders recognize this, all the cultivars I have experienced have that old fashioned smell we love. What we have today are cultivars that are smaller in stature and differences in flower size. The dwarf one is often listed as Minnisota snowflake grwoing in the 4 foot range. Natchez has 2 inch single blooms at about 6 -8 feet. The more traditional Mock Orange will get 8 feet in size or more.
