Only a very small percentage of those plants tested are chosen to be introduced nationwide as All-America Selections. The All-America label is considered the highest honor a flower or vegetable can receive in this country. Petunias used to be pretty delicate and somewhat cantankerous in the garden, but the new varieties are easier to grow, and more drought and weather tolerant. Only the flower color can be described as soft or delicate, as the plant is tough. Plants are reliable, growing about 18 inches tall in a sunny garden.
All growth is horizontal.
Purple Wave is the first petunia with a ground cover habit. As the name implies, the color is a deep true solid purple. The plant is ideal when used as a ground cover or in rock gardens, on sloping hills or terraces, and is heat and dry weather tolerant. Rudbeckia also is known as the gloriosa daisy and is native to the eastern United States. This free-flowering new variety bears huge golden blooms 6 to 9 inches across.
