I bought a pack of zinnia plants from one of my favorite nurseries, Blanco Gardens in Blanco, Texas this summer. They had yellow, orange, light pink and dark pink flowers in the mix. These zinnias grow in a mounded form and are excellent bloomers, especially is you deadhead frequently. The butterflies seem to like the cheerful orange ones the most. Our fall weather has been mild with temperatures in the 90F during the day dropping into the low 70F at night and these flowers are not showing any signs of slowing down.
