From retired plant breeder Dr. Moy at the San Antonio Botanical Garden comes this giant-flowered mallow hybrid that took Texas by storm. H. 'Moy Grande' certainly boasts one of the largest flowers we have seen on a hardy hibiscus, reaching sizes in excess of 1' across when grown in rich moist soils...what else could you expect from Texas, but BIG? Dozens of the giant, bright, rosy, blue-red flowers adorn the 5' tall x 5' wide clump each day from midsummer until early fall. Pot size: 24 fl. oz (709.77 ml)
