Mike, it isn't a haiku. It is a tanka and a good one. http://www.tankasocietyofamerica.org/ Please visit the Tanka Society of America's website where you will find much information and many more fine examples of the form which is much older that haiku.
A deep reminder of how powerful our sense of smell can be in bringing us into the present. Scent is often overlooked in both poetry and life in this age. This tanka reminds me of the many moments that scent has made me feel more alive. Beautiful.
