Aster Family flowers usually look something like a sunflower, that is, they usually have an obvious central disk surrounded by rays. There are exceptions. For yellow to orange flowers that aren't in the Aster Family, click here.
Flowers are shown in alphabetical order by genus and species. Click on a link to reach the family page and find additional photos of a species, plus comments. That pages is bandwidth-intensive and best used with a high speed connection.
I am reorganizing my web pages for the aster family. At the moment, links to flowers of that family may not take you directly to the correct page. Please be patient until I find the time to update all the links.
