Why does the red queen use opposites to describe the garden and the hill?

Once outside, Alice climbs a nearby hill to get a better look at the garden near the house. However, every time she begins to follow the path to the hill, she finds herself back at the door to the house. Dismayed, she mentions her frustration to Tiger-lily, who surprises her by responding in perfect English. The Tiger-lily explains that all flowers can talk. The Rose chimes in and mentions that Alice does not look very clever. Alice asks them if they feel at all vulnerable. They explain to her that they are protected by a nearby tree that will bark at any approaching threats. The Daisies begin caterwauling and Alice silences them by threatening to pick them.
