The Dallas Arboretum is a spacious garden that has a variety of beautiful and interesting separate gardens to see while you're there. Admission is cheap, and the Women's Garden is particularly worthwhile, with a gorgeous fountain and sculptures that instill a sense of tranquilty in visitors. They host special envents (weddings, etc.) and often have special things planned, such as concerts in the park and art festivals. The grounds are impeccable and the flowers and plants are all labeled, so you can find your own seeds to plant the ones you most admire.
