Diabetes affects our blood vessels and nerves and therefore can affect any part of the body. However, certain parts of our body are affected more than other parts.
I don't think dogwoods have (much?) scent, maybe just lightly floral. The white petally looking things are not actually petals they are bracts, like a poinsettia has. There's something called an English dogwood that is very fragrant, but it isn't a true dogwood and is also known as mock orange. Bradford pears have a smell that this author described as sweaty socks, so if your tree doesn't smell very good that's probably it: http://www.gardenguides.com/106133-dogw ...
Both drought and poor drainage can cause dogwood trees not to bloom. Pacific and kousa dogwoods are more tolerant of drought conditions than flowering dogwoods. Provide 1 inch of water per week to young dogwood trees up to six years old. Dogwood tree roots are shallow.Soak the ground to a depth of 6 inches to ensure adequate moisture in well-drained soil.oth drought and poor drainage can cause dogwood trees not to bloom.
