Notable species include Haplocartha scaposa introduced from South Africa by Mr. Beamish, together with the rare Mexican White Pine, the tallest in Ireland and Britain.
The first phase of the garden lay-out was carried out by Lord Bantry between 1791 and 1795. The work was continued by his eldest son Richard between 1844 and 1868, and influenced by his wide continental travels. Extensive restoration has recently been carried out on the gardens. ,

The Royal Cork Institution was set up in 1803 and received a Parliamentary grant of two thousand pounds per year. The Governors decided to establish a botanical garden, and in 1807 leased a site at 'Lilliput', Ballypehane, Cork. In 1808 they employed Scotsman James Drummond to lay out the gardens. In 1822 the garden was described as having approximately six acres and a glasshouse in a walled enclosure of. Drummond was a noted field botanist during his time in Cork. The Government grant was withdrawn in 1830 and the Governors declined Drummond's offer to lease the gardens and opted to surrender the lease. The lands were then let to Fr. Mathew of Temperance fame for a cemetery which use still continues. The only current evidence of the gardens is a cedar tree. , ,

Two miles from Bantry in the Mealagh Valley. The property was owned by the White family from the 1790s until 1853 when Major Arthur Wilkinson bought it. After 1880 Drombow Lake was selected for a reservoir; this gave the impetus to Arthur Berkeley Wilkinson to build a series of water gardens, dedicated to the cultivation of water lilies. The gardens also contained a range of wayside flowers supplied from Glasnevin, and in turn Drombrow supplied Glasnevin with bamboo, waterlily, phlox and butterwort. After Wilkinson's death the estate was neglected and the water garden fell into disrepair.
