Tuberous begonias have stunning blooms and textured foliage. But they take some care to keep them looking fresh. They prefer part sun, as they cannot take the hot summer sun. They are a rarity in that they bloom best in the shade. They also cannot stand in water, so avoid over-watering in early summer. Although they may require more attention, the pay off of these glowing blooms is worth it.
