Powis Castle at Welshpool, Powys, is opening for the first time this year on Sunday, 1 March.
The snowdrops are out just in time for the opening of the gardens, which stay open until 9 November.
There are 25 acres (10ha) of gardens at the castle.
They include five terrace gardens, and this is the orangery terrace. All five are said to be among the best surviving examples of baroque garden architecture in the UK.
The orangery terrace is 120m long and has a double herbaceous border of plants mainly from the Mediterranean.
Four gardeners spend three months trimming the hedges during the growing season.
