One flower growing next to another, particularly different species can't affect the color of the other. Perhaps the blooms are fading in the heat, perhaps some extra nasturtium seeds have germinated? But the color of the nasturtium has nothing to do with the petunia. Linda C

Gorgeous cym!!! I too like natural stakes and keep looking for things I can use. I once had a tiny branch of a crepe myrtle root, LOL. I'll have to watch for trimmed fronds, never thought of them before. Thx for the tip. Sheila :)

Paul, I visited a dahlia farm this year and the owner told me you have to keep and watch dahlias for something like 3-4 years to make sure EVERY FLOWER is always the same. Then they are called show dahlias and you can enter them in shows. I thought I was confused about some of mine because I would take a picture of a bloom and the next picture I would take was different. I thought I was getting the names confused. Shirley

sorry jerseybobmc, my answer above was for the two color flower on the other post. Your color was brought out by more heat and humidity. Many flowers do not show intense colors in cooler or dryer conditions. It just showed its real colors when given more similar conditions to the tropics where it is from.
