Ju's youngest son, museum director Ju Yuen-li, points out that tall trees wouldn't work because if they were placed next to a large work, the space would seem crowded, and if placed next to a small work they would overpower it. "That's why we chose the grey milkwood tree. It's just the right height, and doesn't steal the show from the sculpture."
朱銘美術館館長、也是朱銘幼子的朱原利指出，樹太高，放在大作品旁邊顯得擁擠，放在小作品邊又會以大欺小，「因此選擇不高的海芒果，是因為它們具有陪襯的效果，又不會搶掉主題。」
