Then Boyd placed a series of waterfalls and pools between fern grottos, hosta groves, walkways and seating areas. He was assisted by three neighbors: an electrician, a builder and a plumber.
The project involved 1,000 bags of mortar mix, 800 bags of concrete, 80,000 pounds of sand and at least 200,000 pounds of rock. "You can't imagine how much rock that is," he says wryly.
"Tom laid every stone," says Burdick, estimating that it took more than 2,400 hours. "That doesn't have anything to do with putting in dirt or planting." She worked her magic by planting hostas and ferns between water cascades. Clusters of purple verbena and yellow day lilies catch the morning sun.
"I love the textures and different colors of plants so I have tried really hard to incorporate that in this garden," she says.
An arrangement of foam flower, "palace purple" heuchera, lady ferns, turtleheads, Japanese iris and primroses are situated at the top level. Foxgloves, daylilies, Solomon's seal, and a stunning Japanese painted fern encircle a birdhouse in a lower section.
"What's nice about this garden is that it's shaded on one side and sunny on the other, so I am able to use plants that like sun and shade." The garden has 25 types of hostas and 15 types of ferns.
Waterfalls and plants are illuminated in the evenings. The couple frequently entertains guests here and on a patio adjoining the house. Last June they hosted a dinner party for 100 people, and this summer they will have a family reunion with 80 guests.
Boyd's grandchildren consider the waterfall garden a "wet 'n' wild" theme park. They play croquet and horseshoes in a glade beyond the house and enjoy their own Tom Sawyer adventures on a log raft in the pond. A cheerful melange of sculpture reveals the pleasure of the place and the couple's intent to celebrate life and being with the people they love. "I like whimsy in my garden. Just to get a smile on someone's face, it's just so worth it," says Burdick.
The Idaho native got a love for gardening from her mother and grandmother. "I guess I am a natural, a born lover of plants. It's a passion. I love to try new plants. If I see something new in a nursery, I have to try it."
Boyd, who is CEO of Fi-Shock, Inc., grew up farming in West Tennessee. "I wanted to be a farmer. I love to see things grow. I like digging in the soil. I'd say we spend 5 or 6 hours a day on average in the yard and all weekend," he says.
