Gorgeous Orchids Showcased at US Botanic Garden

Orchids are among the world's most beautiful flowers. Although the blossoms come in different shapes, sizes and colors, they all belong to one of the largest and oldest families of flowering plants on earth. The U.S. Botanic Garden in Washington is showcasing some of the thousands of different orchid varieties in a spectacular exhibit that runs until the first week of April. VOA's Deborah Block takes us there for a fragrant look at the exotic world of orchids.
