The narrator doesn't tell us much about the effect on Miss Lottie of the external conflict over the marigolds. Use details that the narrator does provide.

From the text, we can infer that Miss Lottie was defeated.... the marigolds.... her one source of enjoyment were gone in an instant.

I opened my swollen eyes and saw in front of me a pair of large, calloused feet; my gaze lifted to the swollen legs, the age-distorted body clad in a tight cotton nightdress, and then the shadowed Indian face surrounded by stubby white hair. And there was no rage in the face now, now that the garden was destroyed and there was nothing any longer to be protected.
