Steve and Tom Sanna oversee Bristol's Garden Center, a verdant, 11-acre garden and nursery that has been greening up the Rochester region for more than 25 years. Their flora emporium blooms with more than 900 varieties of trees, shrubs, and specialty plants ranging from red maple and spruce to dwarf evergreens and ornamental trees. Cacti, houseplants, and cascading fountains fill their tropical greenhouse with sweet scents and calming sounds, and leafy residents in the covered greenhouses include perennials, ornamental grasses, and hostas. The center's garden store arms DIYers with tools, soils, and fertilizers, and professional landscapers lend out their services to customers whose thumbs are flesh-colored instead of green.
