Prism Yellow Petunia has blooms that are a sunny yellow in the center with a light yellow rim around the outer edge. They have trumpet-shaped flowers that are 3 inches across. They are popular for their large flowers and their excellent garden performance. Prism Yellow is free flowering, and the plants are compact and bushy. They also have a good disease resistance.
Petunias come in a wide variety of bright colors and may be solid in color or edged, striped, or starred with a contrasting color. Petunias do well from early spring until late fall. In the fall, Petunias are excellent plants to fill in if you have to replace any summer plants in early September when it is still too warm for Pansies. Petunias are able to handle the warmer weather of late summer/early fall and the cooler weather of mid- to late fall. They will survive light frosts, but the blooms will probably get some frost damage. A hard frost will kill most varieties of petunias.
Prism Yellow Petunia is easy to grow. It does well in a wide variety of soils. Petunias can an be pinched after the initial flowering to maintain bushiness and promote new flower growth, or they can be left to grow naturally. Petunias are fragrant and attract butterflies.
