珙桐是国家一级保护树种,有活化石之称。因花开时似白鸽展翅,被欧美等国誉为“中华鸽子树”。它自然生长在海拔1000～1800米的高寒山区,一般生长8～10年以上才能开花,而且是高大乔木。很多林业科研人员都想把它矮化,作为园林观赏植物引进入公园、民居,但很难如愿。 Davidia is a national protected species, known as living fossils. When it blooms like white doves, it is honored as “Chinese Dove Tree” by Europe and the United States. It grows naturally in the alpine mountains of 1000 ~ 1800 meters above sea level, usually grow more than 8 to 10 years before flowering, but also tall trees. Many forestry researchers want to dwarf it as a garden ornamental plant into the park, residential, but difficult to do so.
