Adds sparkle and light. Healthy, cleanly white

This has been a great zinnia. Mildew free, very floriferous, even without deadheading, though I really should have deadheaded for a better appearance.These grew rounder, more dome-shaped to ball-shaped than the picture here suggests, but I liked them that way. Perhaps the photo shows less mature flowers. I started these in trays, but I think they would be fine started right in the soil where they are wanted to grow. I always like some white trailing through the garden to help show off other colors.
