She stared at the funeral wreath, full of white lilies. She remembered Daddy’s garden, thriving with lush red roses and golden daffodils.
The second sentence is “telling” the reader about a remembrance. The question to ask is, does the reader absolutely need to know the information about Daddy’s garden right at that moment?
If no, then cut it.
If they do need to know the info, there’s a more active and emotional way to “show” it. For example:
The cloying scent of the funeral wreath made her stomach heave and her throat gag. Daddy would have hated it. Lilies had had no place in his garden among the more stately roses and cheerful daffodils.
It figures that the worst wreath would come from Barnaby Jenkins, the slime. And she was stuck holding it for the next hour.
In the example, I’ve added more emotional reactions to the wreath (heaving, gagging, Daddy hating it) and more emotive words to Daddy’s garden (stately, cheerful). It simply makes the information more alive.
I also added the second paragraph to show why the reader needed to know about the wreath and Daddy’s garden (actually, Daddy’s flower preferences)—the information was needed to explain her emotional reaction in the current action, her holding the darn thing for another hour.
