Assorted florist or houseplant begonias that can be grown with great success indoors or outdoors during the summer that are very tolerant of shady gardens and containers. Rieger begonias produce compact, upright plants with clusters of petite, rosebud-like flowers that bloom continuously in a rainbow of different colors and bicolors. Grow in part shade to shady areas outdoors and bright, indirect light indoors. Begonias prefer well-drained soil with average moisture. Feed regularly with a slow release, multipurpose fertilizer. Follow label instructions. No deadheading necessary, but helps keep the plant tidy and blooming nicely. Mulch 2? to suppress weeds, retain moisture and protect against extremes of soil temperature.
