Not just any Zinnia, my friends, but THE BEST Zinnias you can grow! With top-of-the-line MILDEW RESISTANCE, they don’t wimp out, so you're guaranteed a knockout Summer-Fall display with only a few plants. To 30" tall and 2' across, HEAT AND RAIN resistant and strongly multi-stemmed, 'Giant Scarlet' bears huge, densely double, 5" across flowers for months – especially when you deadhead. Long lasting cut flowers on strong stems. Butterflies! Best in loamy soil with compost added.
