The Tree of Life garden has been designed by Pershore College part-time lecturer Carol Smith from a concept by its head of horticulture Tony Davies.
The garden will be on display at the Malvern show on 7-10 May, before being replanted at St Richard's Hospice in Worcester.
The theme of the garden is inspired by aspects of ancient garden philosophy, including Celtic and Islamic symbolism.
The centre piece is the Tree of Life - a birch - which is surrounded by a circle of water leading to four rills dividing the garden.
Davies explained: "We wanted to create a space where patients, their families, staff and volunteers can find a sense of security and of being protected.
"Being among nature reminds us of the cycle of life from birth to the finality of death, which in turn gives rise to rebirth and regeneration. The Tree of Life is representative of life itself - trees provide us with shelter, colour (and) flowers, but more importantly they release oxygen and water without which we could not survive."
A selection of trees including rowan, ash, alder, willow and oak will be featured in the garden.
Students from Pershore will help build the garden at the showground and at the hospice this summer.
