Petunia is a great border plant. Given good sun exposure Petunias are a great choice. Sometimes fragrant but always colorful.
Petunias have funnel-shaped flowers and there are multiflora and Grandiflora varieties. They range in pinks, roses, purple, lavender, white, blue, purple, salmon. Petunia blooms July to September. Petunia is another perennial grown as annual. Feed monthly with fertilizer. Tobacco budworm maybe a problem with Petunias.
