Why does the Helen considered the old fashion garden as a paradise of her childhood?

The garden was Helen's escape, a place she could wander, touch, and smell..... a place where she had freedom, and a place where she could imagine, and a place of comfort.

Even in the days before my teacher came, I used to feel along the square stiff boxwood hedges, and, guided by the sense of smell would find the first violets and lilies. There, too, after a fit of temper, I went to find comfort and to hide my hot face in the cool leaves and grass. What joy it was to lose myself in that garden of flowers, to wander happily from spot to spot, until, coming suddenly upon a beautiful vine, I recognized it by its leaves and blossoms, and knew it was the vine which covered the tumble-down summer-house at the farther end of the garden! Here, also, were trailing clematis, drooping jessamine, and some rare sweet flowers called butterfly lilies, because their fragile petals resemble butterflies' wings. But the roses—they were loveliest of all. Never have I found in the greenhouses of the North such heart-satisfying roses as the climbing roses of my southern home. They used to hang in long festoons from our porch, filling the whole air with their fragrance, untainted by any earthy smell; and in the early morning, washed in the dew, they felt so soft, so pure, I could not help wondering if they did not resemble the asphodels of God's garden.

Memories are something which never fades away or diminishes .somewhere in our heart it stays forever and ever ..

same is with Helen too she never forgot or wish to forget about all those sweet and sour memories related to that garden which she called her paradise .she alawys used to say -
