For sizzling color in pots and hanging baskets, it’s hard to beat these perennials—each blooms as flouncy and vibrant as a Mexican dancer’s skirt. Flowers come in every shade but blue. Hanging types bloom more profusely, but upright strains have larger flowers—you choose.
These begonias grow best in filtered shade and rich soil; water them enough to keep the soil moist but not soggy, and mist regularly.
