The garden's founder, Henry Davis Pochin, was a Leicestershire-born Victorian industrial chemist who acquired fame and fortune inventing a process for clarifying rosin used in soap, turning it from the traditional brown to white.
Pochin bought the Bodnant estate in 1874 and employed Edward Milner, apprentice to Joseph Paxton, to redesign the land around the existing Georgian mansion house, then just lawns and pasture.
This was a massive earth-moving project done by men without machinery, which involved levelling the hillside and building granite buttress walls which provided protection for tender plants being introduced to the garden from overseas.
Grade II-listed for architectural interest, it was designed by architects W J Green of London, whilst the spectacular marble inside was sculpted by Samuel Barfield of Leicester.
Above the arched entrance with voussoirs supported on columns of red marble, is a sandstone band inscribed ‘The Poem’ in raised decorative lettering.
Henry Pochin's legacy to Bodnant was planting the garden's great conifers; the cedars on the Lily Terrace (from Africa and Middle East) and the Pinetum in the Dell which includes American and Asian conifers including Pseudotsuga menziesii (Douglas Fir) Pinus radiata, Sciadopitys verticella (Japanese Umbrella Pine), Chamaecyparis pisifera (Japanese false cypress and Sequoiadendron giganteum (Giant Redwood).
The next phase of plant hunting was under Pochin's grandson Henry McLaren, 2nd Lord Aberconway who sponsored expeditions from the Edwardian period which brought in large numbers of rhododendrons, camellias and magnolias to Britain.
Notable plant hunters connected to Bodnant Garden included Ernest Wilson, who travelled extensively in China.
He was first engaged by famous Veitch Nursery with the specific task of bringing back seeds of the Handkerchief Tree (Davidia involucrata), one of which still grows in Bodnant Garden's Shrub Borders.
He also brought back many magnolias for which the garden is famous, and other trees including the Acer griseum, Meliosma beaniana and Sorbus meliosmifolia.
Frank Kingdon-Ward conducted numerous expeditions to the Himalayas during the 1920s and 1930s which resulted in the introduction of a prolific number of new species to Bodnant Garden including the Himalayan Blue Poppy (Meconopsis betonicifolia).
In 1925 Harold Frederick Comber was sponsored by garden owners calling themselves the Andes Syndicate, headed by Lord Aberconway, to travel in South America.
Great care was taken to protect some of Harold Comber's other introductions from South America, many of which were planted against a sheltered wall behind the Laburnum Arch.
