It is the third year that John and Sally Waddington and their team - previously at Copseys - have taken on the event, which lasts for three days (3-5 June) and this year it is expected to attract around 15,000 visitors.
Many of the flowers this year are exotics, said managing director Sally Waddington, with flowers arriving from Holland, Columbia and Kenya. But Alstroemeria, Calla lilies, Statice, Limonium, sweet peas, lilies and Lisianthus will be grown at Chidham near the company's base in Havant, Hampshire.
Around 230 flower arrangers will turn them into 57 floral arrangements, the largest of which will have budgets of £3-4,000.
As most of the flowers are still in good condition at the end of the three days, the displays are taken apart and sold in bunches to visitors. Trust director Alison Godfrey said the potential income had not yet been allocated but a major upcoming project was the restoration of two huge Tudor paintings.
