If you look at the comment thread, you will discover that I made a mistake in identifying this flower. It is not a chrysanthemum at all, but a dahlia. It is apparently a common error since they look so much alike. Remember, when in doubt, look at the leaves!
Chrysanthemum morifolium or the “Hardy Garden Mum” is what I thought this flower was, until I was informed otherwise. It is a Dahlia.
Euphorbia Millii or the Thai rose
