All petunias want to be rose colored that is sort of the natural color of the wild petunia. Breeders have spent years developing all the other flower colors with yellow being the hardest color to make. When we saw this Lemon Zest we just stopped dead in our tracks it is a GREAT color. It is bright the petunia holds the flowers up where we can see all the color we really like this flower! And it is yellow!
So 2 things to do with Lemon Zest first plant this flower as a highlight plant because it will pop in your landscape with a bright yellow sort of like a highlight pen will pop on a printed page. Plant it in clusters or by itself just dial up the color.
Second like all petunias Lemon Zest is a hungry. We find petunias like about twice the plant food of other flowers. So make sure it is well fertilized and when in doubt feed.
