Dear Station Members,
Attached is a research article by a Mainland Chinese University published in national newspaper regarding their findings on adopting Liriodendron cultivars in China landscape.
Liriodendron has been thought to be a landscaping tree only suitable for growing in northern China for years already. However, ETF has taken trial production for the indigenous Liriodendron chinensis since 2006 & has found the L. chinensis growing without difficulties in Guangdong climate so far from seeds. Pictures of the L. chinensis in ETF are attached for general reference.
L. chinensis naturally grows with a Central Leader, & would maintain a +60% Live Crown Ratio if not disturbed. It has been found to be a rather slow growing tree in ETF despite overseas reports, & would grow two times a year in spring & autumn primarily. It has been found to be relatively pest resistant & responded well to PHC treatment. The tree would naturally develop into Tear Drop Shape which is the best shape for wind resistance if Structural Pruning can be provided.
Liriodendron species has hardly been promoted in HK landscape like many other indigenous Chinese species which are now undergoing discovery by the Chinese landscapers one by one. China has always maintained a pragmatic approach in choosing their Urban Trees since their Landscape Bureau would need to care for their trees from cradle to grave. Their Landscape Engineers also appear to take an attitude in their Street Tree Selection by not going for 'flowering' & 'scent' alone. However, they equally face the problem of having limited space in Tree Installation which appears to be a universal challenge in our cities.
L. chinensis has a unique leaf shape like a traditional Chinese costume. In fact, that's how it gets its name over the years. It would be good to see this new species to go on trial in HK some time for enrichment in our local Tree Selection.
best regards,
