Note1: If you have things you want to say but don’t know how to write it in Japanese, just try to write some parts (eve just some words) and ask me how to write the rest! I can teach you or provide some hints.
More accurately, I’m a bit confused both about the なんか and the entire 「げんきがでる花」… just goes to show how lacking my grammar knowledge is ^^"
EDIT: A little more research suggests 元気が出る花 could mean something like “cheerful flower?” I think the full sentence in English would be something like “A somewhat cheerful flower, isn’t it?”
The colours of the flowers change depending on the acidity of the soil.(pH) By knowing the acidity of the soil, it helps gardeners know which flowers to plant. Some flowers can only grow in acidic soil, others can only grow in basic soil.

Even if you can’t explain it in simple Japanese, at least you may learn something new.
