flower id: dahlia

some dahlias i picked from my autumn garden. they are seemingly flawless. look at their petals, perfect symmetry ! my favorite part of a dahlia is their celery-like smell when you snip the stems. they bloom late summer- autumn around here and are one of my favorties to use in fresh arrangements. i also think the name is so pretty. so much so that I tried to persuade my husband to name our last little baby dahlia, call her dolly for short. he didn't like it... :(
