The company donated a wide range of the summer-flowering bulbs, which will brighten the entrance to the historic West Sussex Garden, due to reopen in March.
The 7ha of formal gardens at Borde Hill were first opened to the public in 1965 and they have since won numerous awards and earned a Grade II listing from English Heritage.
They flank a 16th-century Tudor mansion house, which is set in 81ha of park and woodland.
Spalding's bulbs were chosen by Borde Hill’s new head gardener Andy Stevens and they include hundreds of vibrant lilies, like Lilium 'Tiger Play'.
The new Spalding Plant & Bulb Company catalogue will be launched in January and features more than 50 new introductions, including varieties for patios, borders and ponds.
The 100-page catalogue will showcase a full range of perennials, climbers, roses, shrubs, ground cover, conifers, hedges, houseplants, fertilisers, fruit, vegetables and garden accessories.
Borde Hill will receive 50 Mariposa lily 'Violet Queen' and 50 Camassia 'Blue Melody', as well as 100 tiger flowers, 25 Gladioli 'Black Jack' and Gladioli 'Zizanie' and 26 Ornithogalum Dubium. Smaller quantities of various lilies will also be sent.
