A single produces hundreds of 2" flowers on stiff stems that grow up about a foot before cascading gently down into fountains of color. With it's seductive color, Tidal Wave ™ Cherry makes a 10" spreading mound. Spaced a foot apart in a row, several form a mounded hedge 16-20" tall. Scrambling through taller companions in a pot, they get 2-3' tall. Another exciting new petunia! Burpee Exclusive. Sun.
