unusual downward-hanging flowers with nine pure white petals, and rich red stamens, and also found a large specimen of the quite rare Michelia doltsopa, also with rich white, scented flowers. A Metasequoia glyptostroboides gave us one of many chances to benefit from Maggie's knowledge, and showed again how recent so much of our knowledge is. The tree was spotted in 1941 by a forester in Sichuan who, being unable to identify it sent leaves to Beijing. By extraordinary coincidence, a Japanese palaeobotanist was working on three-million-year-old fossils of the same tree, thought to be long extinct, and in 1946 the connection was made between the two. Like the Ginkgo biloba, therefore, this is a fossil survival - and whereas it is struggling to survive in its remote Sichuan valley, thanks to gardens like this it is actually thriving in Britain, and is now widely available. This was a theme we came across in several gardens: British horticulture feeding plants back to their original countries.
Heligan is now one of the best known gardens in Britain, thanks to the televising of its restoration. Its 80 acres had almost disappeared into jungly luxuriance thanks to some 70 years of neglect, and were only "re-discovered" in 1990 thanks to a conversation in the pub at St. Ewe between its new owner John Willis, and one Tim Smit (now Director of the Eden Project). The gardens as we see them now are the design commissioned from Thomas Gray by Henry Hawkins Tremayne in 1780, and the last major planting was done before the First World War. Of the 22 gardeners then, all signed up; two thirds were killed, and none returned. The Tremayne family had six houses, and moved to Crone Manor, leaving Heligan tenanted but the gardens neglected, and the rest, as they say, is history.
We were taken around Heligan by Colin Howlett, whose familiarity with the project since its inception gave us a wonderful insight into its work. Many of the early plantings still visible are the results of Joseph Hooker's 1848-1850 collecting in Sikkim, which were distributed by himself and by Kew almost immediately on his return: 23 of the rhododendrons at Heligan are Hooker plantings, as is the Crinodendron, and the Magnolia campbellii collected by him is now the largest of the magnolias at 60 feet in height. Thanks to the long neglect of the gardens, however, many of the rhododendrons have hybridised, with the result that Heligan now has the job of identifying and naming many new hybrids; this is also true of its camellias.
