Zinnias are one of the easiest annuals to grow, and attract butterflies to the garden. They thrive in the sun and heat of summer, and ask only for well-drained soil. Space the plants generously to prevent overcrowding. Profusion is highly tolerant of mildew and other foliage diseases, and laughs at heat, humidity, and drought. The Profusion series grows only 12-15″ high. State Fair Mix grows taller, up to 30″ and with larger flowers in an array of colors, measuring up to 5″ across. Perfect for cutting!
