Forty-nine years ago, my husband, Frank, of only a few months, and my father dug up a silver maple sapling from the yard of the home where I had spent my teen years. Back in the 1970s, people often planted silver maples for quick shade because the trees can grow three to seven feet a year. We brought the little tree north and planted it in the front yard of our Wisconsin Dells home.

Like most things worth having, Maple required care: watering, pruning, and protection. That first winter, Frank sometimes covered the tiny sapling with a five-gallon pail to protect it from the cold and keep rabbits from nibbling it. Our dog Ginger helped too, chasing rabbits from the yard while Maple slowly took root.

Over the years, Maple quietly witnessed the rhythm of our family life. She watched Ginger, who once pulled our daughters through the snow on a sled, grow arthritic with age. She shaded our second dog, Josie, when she was still a playful pup. Now our newest puppy romps beneath her branches, proudly dragging around sticks that have fallen from the tree itself.

Maple and I, we have history.

Silver maples are beautiful trees, but they are not exactly low-maintenance. Their branches become brittle over time and are always dropping. As the years passed, we hauled away enough fallen limbs and leaves to raise the city's compost pile by at least a few inches. Her roots sneak into my flower gardens much like my grandson sneaks into the candy drawer. Still, I willingly put up with Maple’s minor faults because she has been part of our lives for nearly half a century.

I was there alongside the Racine pond when her parent tree dropped the spinning samara seed that eventually sprouted into the sapling we carried home. She was there the day Frank and I celebrated our wedding with an outdoor dinner reception near where Maple first grew. Not long after my father and Frank transplanted the little tree to our yard, my father passed away.

Now, on windy days when the silver undersides of Maple’s leaves flip and shimmer in the sunlight, making the whole tree appear to sparkle, I often think of my father.

Over the decades, Maple has quietly marked the passing of our lives. When our son Jon was four years old, he helped me rake leaves into giant piles before hurling himself into them like a long-distance jumper. Our daughters chased Maple’s spinning “helicopters” as they twirled through the air on breezy afternoons. During summer days, they carried their guinea pigs, Misty and Caramel, beneath her branches where the shade was cooler.

Today, Maple towers above the rooftop. Her roots have spread deep and wide across the front yard, much like the friendships and memories I’ve built here. And like me, she has grown a little creaky with age.

The children are grown now, with homes and lives of their own, yet Maple remains rooted in the same spot she has occupied for nearly five decades—steadfast, familiar, keeping sentry over the yard and the family that grew up around her. Silver maples typically live eighty to one hundred years, so there is a good chance Maple may outlive Frank and me, standing watch as new generations come and go.

The other day, I carried my trowel into the flower garden and began digging weeds. As I worked, I noticed a tiny maple seedling pushing through the soil.

Normally, I would have pulled it.

Instead, I paused and looked over at Maple swaying gently in the breeze.

Then I left the little sapling right where it was.
